EARTH STRUCTURE VAN DER PLUIJM PDF

Steve holds an A. An Introduction to Structural Geology and Tectonics takes a balanced approach to the subject—emphasizing links between structural features at all scales microscopic, hand-specimen, outcrop, mountain-range and deformation processes. These chapters allow the book to be used either for a one-semester course that relates plujim to tectonic settings or for a succession of two courses one on structure and one on tectonicsthus enabling students to buy just one book. Earth Structure shows how assemblages of structures relate to different geological settings in the context of plate tectonics.

News Fall Geoscience newsletter Ben van der Pluijm and collaborators are continuing their research on orogenic geofluid sources and timing, focusing on the US and Canadian Rockies and the US Appalachians. This summer, Erin Lynch completed her PhD on orogenic fluid fingerprinting and now shares her talents at Shell, following an academia-to-industry path of many of his recent PhD students.

As a reward, Ben got the Michigan Stadium to himself to punt some seismometers photo. Samantha Nemkin, in a project with Rob Van der Voo, finalized her research on synfolding remagnetization, showing this is very common in the Rocky Mountains and its equivalent in Mexico. A third paper, on the Monterrey orocline in northern Mexico, was just accepted for publication. Austin Boles completed his studies on clays in a range of deformation settings, and the development of a more advanced X-ray clay characterization method.

The continuing research of graduate student Erin Lynch focuses on geofluid fingerprinting in the Rockies and Appalachians, building on a recently published study in the Argentine Precordillera that finds a regional climate signal in fault rocks. She enters her final year with a Rackham Predoctoral Award, allowing uninterrupted time to complete and defend her dissertation in mid Ben has expanded his professional efforts and outreach activities in societal resilience, which is the focus of a Fall class and will be incorporated in future teaching of intro geology.

SE Alaska picture. Some personal travel, meetings and service trips, and a new puppy, Luca, keep Ben and Lies nicely occupied. Already, we are nearing the 1. The implications of global warming are recognized widely, both in short-term events like coastal inundation and extreme weather, and long-term in the form of permanently shifting climate zones and higher sea level.

The range of our actions, however, is not limited to greenhouse gas generation only. It publishes peer-reviewed articles, reviews and short and long-form commentaries in areas that include water, air, food, energy, hazards, climate, ecosystems, human well-being and demographics, among others.

Contributions focus on Earth as an interconnected, evolving system to inform researchers, policy makers and the public on the science of the Anthropocene. One novel element is the use of authoritative commentaries that critically examine a topic with a solid scientific foundation. For example, one such set is just published on the controversial topic of climate engineering. Over the summer, Ben also worked on a new version of the successful Earth Structure textbook, which changed so much that a new title will be used.

An experiment with online posting is underway, allowing greater international access and lower prices see earthstructureweb on Facebook. Graduate student Austin Boles continues the development of H analysis as a proxy of fluid sources, most recently on samples from the Alpine Fault of New Zealand.

Erin Lynch is similarly working on sources and timing of fluid history, focusing her efforts on the Cordilleran fold-thrust belts of S and N America. Samantha Nemkin, jointly supervised with Rob van der Voo, continues her work on the timing of remagnetization using the paleomagnetic fold test in limestones and fold dating of interbedded shales. Several undergraduate students are also involved in these projects. These views are not embraced by everyone.

Ben and Lies continue to host U-M alumni travel, most recently to the Barents and White seas, visiting Russian harbor cities like Murmansk and Arkhangelsk picture , seeing samples from the bottom of the Kola Peninsula deep hole 12 km!

Ben capitalizes on his experiences in education and outreach in sustainability science for this role, but has also not forgotten structural geology.

A return to teaching structure using, surprisingly? Its mission is to focus on the Earth as an interactive, evolving system to help researchers, policy makers and the public navigate the science.

During the last decades, decision-makers in public service and private sectors have increasingly realized that the major challenges facing human society in the 21st century will be related to the evolution of the Earth system. Among the global challenges are the limitation of available natural resources, the rapid population growth and its concentration in large urban areas, climate change with its impacts on the environment and society, the human and economic impacts of hazards such as earthquakes and extreme weather, air and water quality, sea-level rise, reduction in biodiversity, etc.

All such decisions will have to be based on scientific knowledge and understanding of the governing processes. It is, therefore, the responsibility of the scientific community to develop programs that will help society address these key challenges in the decades ahead. Many of the questions posed by stakeholders require interdisciplinary approaches. They will not be left to individual scientists nor even to scientific teams, but will often require a close dialogue with various players in society and the co-production of knowledge involving different partners.

About two years ago, the American Geophysical Union constituted a task force to assess new journal concepts for the Union. The task force noted that the scientific landscape has been evolving toward more integrated, transdisciplinary science and toward more societally relevant research that is geared toward solutions to coupled human and planetary challenges. The task force noted that AGU has produced many successful journals in the past decades that cover a large spectrum of geophysical disciplines, but that there is a recognized need to better link these disciplines with, when appropriate, economic and social processes.

It publishes papers that emphasize the Earth as an interactive system under the influence of the human enterprise.

It provides science-based knowledge on risks and opportunities related with environmental changes. The journal will include regular research papers, review papers, commentaries and essays in support of its stated goals.

A permanent editorial team led by the new Editor-in-Chief BvdP is being constituted and will assume responsibility for future issues of the journal. Guy P. Meanwhile, Ben was able to remain actively engaged in research through the efforts of a group of wonderful students and colleagues. Research scientist Anja Schleicher published our final? Our collective efforts in this project convincingly confirm the starting working hypothesis of clay minerals as the mechanical agent responsible for weak fault, creeping behavior; Ben wrote a short note for Nature Geoscience on this after friction experiments in competing labs demonstrated that SAFOD swelling clays are also very weak in laboratory settings read here.

Post-doc Elisa Fitz-Diaz joined the group last year tackling the high-risk, high-reward project of fold dating. Ar dating of folds would complement our now-established fault dating capabilities, allowing detailed spatio-temporal information along and across fold-thrust belts. The preliminary results are very promising, so stay tuned. Three new students will be joining us this Fall. Austin Boles will examine the fluid history of fault systems using high-resolution O-H isotopic analysis of newly mineralized clays in collaboration with colleagues at Wisconsin and Frankfurt.

Initial sampling work was done by Ben in summer ; see spectacular exposure of the North Anatolian Fault in Turkey in the picture. Samantha Nemkin will work with Rob van der Voo, Elisa and Ben on nature and timing of orogenic curvature in Mexico, while Vera Hehn will work with Eric Hetland and Ben on microseismicity potential and shale properties associated with hydraulic fracturing in the eastern US.

Winter , Eos Transactions In a sustainable world, human needs would be met without chronic harm to the environment and without sacrificing the ability of future generations to meet their needs. Addressing the grand challenge of sustainability, the U. The growing family of SEES activities, currently consisting of 11 programs, represents a major interdisciplinary investment by NSF that reflects the following topical themes: environment, energy and materials, and resilience.

The SEES research and education program portfolio emphasizes the use of systems-based approaches to address critical challenges at the nexus of environmental, energy and materials, and economic systems, including social and behavioral dynamics and questions of human resilience and vulnerability. The SEES portfolio seeks to increase capabilities for understanding, predicting, and responding to changes in the linked natural, social, and built environment.

Within the above three themes of SEES, NSF supports a variety of new programs that are proceeding down three pathways to advance sustainability: 1 building the knowledge base, 2 growing the workforce of the future, and 3 forging critical partnerships.

The research and education communities are strongly encouraged to create interdisciplinary proposals that address aspects of sustainability. Sustainability science, engineering, and education require a multifaceted consideration of the natural environment, human populations, energy and materials use, built environment, and human behavior so that the challenges brought on by large-scale environmental change and modern resource demands—economic, technological, agricultural, and cultural—can be met.

To ensure a healthful future, SEES relies on the energetic engagement of research and education communities from AGU and other scientific organizations to help create, nurture, grow, and disseminate the emerging knowledge base on sustainability. Killeen, T.

Mostly this means a return to the classroom, since the continuation of his research program was well-supported by the university during these years. PDF Charlie Verdel and research scientist Anja Schleicher anchored a research team that has been focusing on fault rocks in a range of settings, from the US Cordillera to the Appalachians, from the San Andreas fault to the Nankai seismogenic zone.

Ben will remain involved in a range of university activities, both at U-M and as a consultant-evaluator nationally, while increasingly directing his interests toward the lower-level undergraduate experience. His appointment left little time for geology fieldwork, but he recently returned to the Canadian Rockies to sample fault rocks at major thrusts in the Jasper area.

Aided by helicopter, access to key locations was a lot easier than past hikes that would easily take a day for one sample, or were impossible to reach. The picture is a helicopter shot of the most frontal thrust near Hinton, showing spectacular footwall folding and a thin fault gouge layer under the folded carbonate cliff.

Getting a sample was tricky, as you can imagine. But the famously violent fault also has quieter sections, where rocks easily slide against each other without giving rise to damaging quakes. The question of why some fault zones creep slowly and steadily while others lock for a time and then shift suddenly and violently, spawning earthquakes, has long puzzled scientists. Some have speculated that fluids facilitate slippage, while others have focused on serpentine—a greenish material that can alter to slippery talc.

But when van der Pluijm and colleagues analyzed samples of rock from an actively creeping segment that was brought up from a depth of two miles below the surface as part of the San Andreas Fault Observatory at Depth SAFOD project picture , they found very little talc.

Instead, they found that fractured rock surfaces were coated with a thin layer of smectitic clay, less than nanometers thick, that acts something like grease on ball bearings. The technique of argon dating provided key evidence, when the researchers determined that these clays, found only in fault rock, formed relatively recently.

The San Andreas fault is actually a network of faults, with new strands being added all the time. Because it takes some time for the slick nanocoatings to develop in a new strand, the unlubricated, new strand "gets stuck" for a time and then shifts in a violent spasm.

Accreditation is a process that universities undergo to make sure they meet certain standards, and to demonstrate to the public — particularly students — the quality of their infrastructure supporting academic programs and other activities. U-M has been accredited since A letter sent last week to President Mary Sue Coleman concludes an extensive two-and-a-half-year process that involved faculty and staff working groups, forums, data collection, a comprehensive self-study, a site visit from a team of higher education leaders, and a thorough final review of the university by several commission teams and its board.

It commended the university on its demonstrated commitment to diversity and outreach activities; a participatory governance structure that includes faculty, staff and students; the strength of its central leadership in a decentralized setting; and the quality of its faculty and staff. Former Provost Teresa Sullivan, who oversaw the accreditation process, says the extensive self-study that comes with the every-decade review is a chance for the university to examine its current operations, reflect on its goals, and incorporate new ideas and insights into its vision for the future.

The university chose internationalization. Clark Collegiate Professor of Geology, who headed the campus reaccreditation process. A more thorough reaction to and analysis of the report will be forthcoming, van der Pluijm says. Outreach I regularly offer presentations or comments for a general public on topics of geology, geohazards and societal resilience. Contact me for information and availability vdpluijm55 gmail.
