Why we look for faults (in the middle of North America)

Looking for faults in the craton (the old part of the North American continent) can be, well, challenging what with all of the dirt and vegetation covering up so much of the rock.  One reason to find these elusive faults is to avoid pumping large volumes of waste water into them and thereby increasing the potential for earthquakes.  Here are some links to news reports about recent studies suggesting that faults and huge volumes of waste water don’t mix.

Undergraduate pre-service teacher-researchers involved in Geoenvironmental Challenges are discovering new ways to use old geologic maps and new field observations to find hard-to-find faults.

Faculty mentor Dr. Mark Abolins recently led a fault-finding field trip in connection with the 2015 Geological Society of America Southeastern Section Meeting in Chattanooga, TN.

GROUNDWORK:

Next Generation Science Standards: A call to action for the geoscience community

How do we ensure the health of our geology departments with a steady stream of majors and build an informed public prepared to make important decisions on geoscience issues? The Next Generation Science Standards (NGSS) are a critical step, and they require the support of geoscientists nationwide.

The NGSS demonstrate an expanded emphasis on earth-science topics (such as natural resource distribution, human impacts on climate, and geologic history) compared to previous standards (NGSS, 2012; National Research Council, 1996). The NGSS present a rare opportunity to significantly improve K–12 earth-science education nationally because they (1) include up-to-date, timely topics important for public decision making; and (2) increase the rigor and prominence of earth-science content in K–12 classrooms. However, adoption of the NGSS requires state-level legislative action. Without support from geoscientists at the state level, the implementation of NGSS nationwide is threatened.

What can you do to ensure quality K–12 earth-science education?

  1. Promote the adoption of the NGSS in your state to local lawmakers and popular media. Check here to learn about NGSS in your state: http://ngss.nsta.org/latest-news/. Major legislative battles are taking place in many states due to push-back on controversial earth-science–relevant topics. Write letters to your lawmakers urging them to support the statewide adoption of NGSS. Write articles for local popular press, or hold a local science café through your institution’s STEM outreach office. Stress the importance of the NGSS for preparing an informed public to make decisions about natural resource use, climate change impacts, and natural hazards.
  2. Urge your state commissioners of education to provide adequate resources for teacher training to meet the Earth and Space Science Performance Expectations in the NGSS. Many local and regional school districts are struggling to adapt to curricular changes as a result of statewide adoption. The resources they need include earth-science content training, curriculum development training, classroom materials, computers, and strategic planning for implementing earth science either as a stand-alone course or infused into their physics, chemistry, and biology courses. The needs and resources of each district vary substantially; however, all schools need teacher training to understand the earth and space science standards and how to best meet the standards within the context of their school districts’ curriculum.
  3. Utilize broader impacts of funded projects to provide content knowledge training to regional teachers. Teachers in your area need a boost in their earth-science knowledge to meet the expectations of the NGSS. Specific challenges relate to understanding how the process of science can be different in the earth sciences as compared to other sciences and how to present politically charged issues, such as climate change, earth history and evolution, and natural resource use (such as fracking). Resources to facilitate your efforts are available through the following organizations and curricular repositories: National Association of Earth Science Teachers, Museum of the Earth, SERC, On the Cutting Edge, and the Geological Society of America, to name a few. Likewise, you can partner with colleagues in a college of education or STEM outreach office to help use the content you provide and to develop appropriate lessons for K–12 classrooms.

April 1 Deadline – Nominate a Teacher for National Presidential Award

A reminder from the Institute for Broadening Participation (IBP) . . .
At IBP, we know that K-12 educators are instrumental in building a strong foundation for a future career in math or science. That’s why we’re excited to share information about the Presidential awards program that honors these outstanding teachers! The Presidential Awards for Excellence in Mathematics and Science Teaching (PAEMST) is the nation’s highest honor for teachers of mathematics and science (including computer science). PAEMST nominations and applications for the 2014-2015 cycle are open for 7-12 grade teachers. Nominations close April 1, 2015. Applications close May 1, 2015

Established by Congress in 1983, the PAEMST program authorizes the President to bestow up to 108 awards each year. NSF administers PAEMST on behalf of The White House Office of Science and Technology Policy. Presidential awardees receive a certificate signed by the President, a trip for two to Washington, D.C., to attend a series of recognition events and professional development opportunities, and a $10,000 award from the National Science Foundation (NSF).

Research and intervention with adolescents exposed to domestic violence. Family Therapy. 2006; 33:45-52. (University of South Carolina Upstate)  The present study examined characteristics of adolescents exposed to domestic violence and tested a group intervention protocol utilizing expressive writing (EW) as a coping method for this population. The experimental group used “Positive Points”, a list of personal strengths, in the writing intervention based on the hypothesis that their use would increase cognitive insight and positive word usage. A significant group effect was found and all participants demonstrated positive overall emotional change as a result of EW. Jennifer Parker is an assistant professor of psychology. Gina Stewart and Courtney Gantt, both senior psychology majors, participated in the research for independent study credit. The research was supported by a USC Scholarly Research and Development Award and a mini grant from the USC Upstate Center for Undergraduate Research, which was awarded to Gina. Gina is currently in a doctoral program in psychology at the University of Mississippi. Courtney is employed and in the process of applying to graduate programs.

ABSTRACT

The authors use mesoscale structures and existing 1:24,000 scale geologic maps to infer the locations of four macroscale NNW-striking blind normal faults on the northwest flank of the Nashville Dome approx. 30 km south of downtown Nashville. The Harpeth River fault zone has an across-strike width of approx. 6 km, and, from west to east, includes the Peytonsville, Arno, McClory Creek, and McDaniel fault zones. All of the fault zones are east-side-down except for the west-side-down Peytonsville fault zone. Mesoscale structures are exposed within each fault zone and are observed at three stops along Tennessee-840 and at an additional stop 1.8 km south of the highway. These structures include minor normal faults (maximum dip separation 3.8 m), non-vertical joints, and mesoscale folds. No faults are depicted on existing geologic maps of the zone, but these maps reveal macroscale folding of the contact between the Ordovician Carters Formation and the overlying Hermitage Formation. The authors use the orientation and amplitude of these folds to constrain the orientation and length of the inferred blind fault zones and the amount of structural relief across the zones. The longest fault zones are the Arno (13.2 km long) and McDaniel (11.6 km) fault zones, and the amount of structural relief across these zones peaks at 27 m and 24 m, respectively.

The authors also use existing geologic maps to hypothesize that a second east-side-down blind normal fault zone (Stones River fault zone) is located approx. 27 km northeast of the Harpeth River fault zone. The authors interpret non-vertical joints at one stop as fault-related, and they interpret joints at a second stop as related to a hanging wall syncline. Both of these stops are within 4 km of Tennessee-840.
