They seem to have been formed by erosion of upper crustal rocks and exhumation of mid-crustal rocks. Lut However, it is not clear how the lower crust and underlying mantle Block have responded. Many core complexes in the western United Zagros States are underlain by a flat Moho discontinuity, and some others Persian possess a crustal root. Here, we present evidence of the Chapedony 30˚N Gulf metamorphic core complex in the Central Iranian plateau. We AR show that the overall lithosphere and continental crust were thinned P A LA B beneath regions of surface extension.

(Kargaranbafghi et al., 2012a). All geochronologic ages are consistent with a period of rapid cooling from 750 °C (migmatite formation, based on U-Pb zircon ages; Ramezani and Tucker, 2003) through ~300 °C (40Ar/39Ar biotite ages; Verdel et al., 2007; Kargaranbafghi et al., 2012a, 2012b) to 50 °C by 30 Ma within <20 million years (Fig. 3). The data presuppose cooling at a rate of ~45–80 °C/ m.y. Using the mentioned mineral thermobarometry (Kargaranbafghi et al., 2012a, 2012b) to constrain the initial depth (12 km), we calculated that the CMCC underwent tectonic unroofing and erosional exhumation at an average rate of ~0.75 –1.3 km/m.y. A seismic receiver function study indicates that the crustal thickness is ~45 km thick between the Persian Gulf coast and the High Zagros. After that, it thickens rapidly to ~70 km within a narrow zone beneath the Sanandaj-Sirjan Zone, before thinning to ~42 km beneath the Urumiyeh-Dokhtar volcanic magmatic arc. At the southern rim of Central Iran, the crust thins to 32–42 km Figure 2.

VISIT THE MARYLAND SCIENCE CENTER Let your mind and senses wander as you explore the numerous hands- on activities at the Maryland Science Center. Featuring an IMAX theater, planetarium, and demo stage, it’s sure to please all visitors.

GET CLOSE TO NATURE AT THE NATIONAL AQUARIUM The National Aquarium houses sharks, dolphins, rays, and tropical fish among the more than 17,000 creatures in naturalistic exhibits, including a walk-through rain forest, an exciting live-action dolphin show, a 4-D Immersion Theater, and an Australia exhibit featuring a 35-foot water- fall. This spectacular aquarium is sure to be a hit with the kids (including the big ones!).

VISIT FORT McHENRY NATIONAL MONUMENT AND HISTORIC SHRINE Just a water-taxi–ride from the Inner Harbor, Fort McHenry was built prior to the War of 1812 and is named for James McHenry, Secretary of War, 1796–1800. The fort played a central role during the Battle of Baltimore, 13–14 Sept. 1814 and inspired Francis Scott Key to write “The Star-Spangled Banner.”

Forty-three were voted on and only four passed and were added to the final version of the bill. This whole process took three weeks of Recap floor time, and by the end of it, this new 114th Congress took more votes than the whole of the 113th.

Human activities (mainly greenhouse‐gas emissions) are the dominant cause of the rapid warming since the middle 1900s (IPCC, 2013). If the upward trend in greenhouse gas concentrations continues, the projected global climate change by the end of the twenty-first century will result in significant impacts on humans and other species. The tangible effects of climate change are already occurring. Addressing the challenges posed by climate change will require a combination of adaptation to the changes that are likely to occur and global reductions of

INTRODUCTION The past few years have seen the rapid development and availability of unmanned aerial vehicles (UAV). Popularly called “drones,” they are remotely operated vehicles that can be fixed- wing aircraft or helicopters. UAVs are being developed for use in everything from product delivery (e.g., Albright, 2014) to farming (e.g., Papadopoulos et al., 2014). Especially popular are micro UAV helicopters, which are usually in the form of small aerial platforms that have four or more propellers (Fig. 1). This configuration provides great maneu- verability, stability, and control. Newer UAVs have built-in GPS systems that provide even greater control and make it easy for an inexperienced person to quickly learn the basics of flying. Their size also makes them easy to transport to even the most remote areas (Fig. 1). They require very little launch and recovery space, and the cost of a basic unit is such that even the total loss of a vehicle is not financially catastrophic (Carrivick et al., 2013). Their low cost also means that multiple UAVs can be used, providing for redun- dancy if one is lost or damaged. Figure 1. An example of a micro UAV, a DJI Phantom 2. The drone has a GoPro camera mounted between the landing gear. USES OF MICRO UAVS IN GEOLOGIC RESEARCH AND TEACHING Although smaller and limited in their instrumentation carrying (Vasuki et al., 2014), generating paleoseismology models (Bemis capacity compared to larger UAVs, the potential use of micro et al., 2014), and surveying post-earthquake land changes (Gong UAVs in geologic research is great, while their small size and et al., 2012). They can give a broad, aerial perspective of geoar- simplicity also make them valuable in educational settings. Aerial chaeological sites (e.g., Eisenbeiss and Sauerbier, 2011) and be used surveys, field mapping, and monitoring can be done in real time in coastal and reef surveys. They have even been flown inside via telemetry, or the collected data can be rapidly downloaded at caves for karst research (McFarlane et al., 2013). the end of a flight. In addition, with the ever-shrinking sizes of In educational settings, mapping exercises can be established sensors, an ever-expanding range of instruments makes the during which students collect their own aerial images and then potential uses of micro UAVs even greater. interpret them. Unlike Google Earth or regular aerial photos, UAVs provide access to areas that are hard to reach and/or structures imaged by UAVs provide greater detail at small scales dangerous, such as vertical or overhanging rock outcrops or gas- (Helmke et al., 2007). Such exercises also provide students with rich and unstable volcanic areas (Fig. 2) (e.g., Ohminato et al., experience in using technical instrumentation, data collection, 2011). They can be used to survey or map disaster areas during data analysis, and interpretation—all critical career skills. The use and after events, such as flooding or mass wasting (e.g., Delacourt of UAVs is also expanding in industry, making familiarity with et al., 2007; Niethammer et al., 2012). They have already been used them a résumé skill (e.g., Muttin, 2011; Morgenthal and for such things as bathymetric and topographic mapping of river Hallermann, 2014). Because of the ease of use and accessibility, channels (Lejot et al., 2007), 3-D mapping of geologic structures they can be especially useful in undergraduate research. GSA 2015 TODAY | JULY

(B) From a micro-UAV image taken directly over the crater, six vents (1–6) are apparent (vents 1–3 correlate with the same numbered vents in [A]).

agency programs. GeoCorps continues to grow and will place almost 200 geoscientists from among more than 2,000 applications in 2015. The number of applications for GeoCorps positions is growing more rapidly than available positions. Donations from individuals help provide positions in addition to those supported through agency budgets. Your support of GeoCorps America when renewing your membership or by providing full or partial funding of a GeoCorps America position will enable GSA to provide more formative experiences to deserving geoscientists. In 2015, donor support was instrumental in providing several positions in Denali National Park and Devil’s Tower National Monument.
