...DANIEL F. MARTT; ABDUL SHAKOOR; BRIAN H. GREENE Abstract The Austin Dam, a concrete gravity structure, failed catastrophically on September 30, 1911, less than 2 years after its construction. Several engineering evaluations of the failure have been made since immediately following the disaster...

..., the lakes have become larger (>1 km 2 ) and drain rapidly through or under the glacier by breaking a terminal ice dam. For the past two surges, since 2001, the lakes formed during or immediately after a surge in an increasingly larger basin between the Neoglacial maximum moraine and an increasingly...

... the Austin Chalk at Howe, Grayson County, Texas, were examined from the Loeblich and Tappan Topotype Collection (NMNH, USNM 473240). These specimens were compared with the holotype and topotypes of Eohastigerinella watersi ( Cushman, 1931 ) deposited in the same collections of the NMNH (USNM 309326...

...Tobias U. Schlegel; Renee Birchall; Tina D. Shelton; James R. Austin Abstract Iron oxide copper-gold (IOCG) deposits form in spatial and genetic relation to hydrothermal iron oxide-alkali-calcic-hydrolytic alteration and thus show a mappable zonation of mineral assemblages toward the orebody...

...Craig S. Fulthorpe; James A. Austin, Jr. Abstract Chirp seismic profiles reveal a prominent seismic facies boundary 0–20 m below the seafloor within an 8.6 × 10.2 km area of the New Jersey outer shelf. This irregular boundary separates seismically transparent facies from underlying stratified...

... 1937-1942. The site is in the west-central part of Travis County, 12 miles northwest (upstream) of Austin, Texas. Besides the concrete part of the dam, wing dikes, earthen embankment, extend on each side to higher ground. The project has a dual purpose of flood control and power development...

... in the range of 2–8 SI; Austin et al., 2014 ). The highest gravity anomalies typically correspond to rocks having high densities related to intense but barren hematite alteration, or to voluminous hematite-rich breccias such as those at the Olympic Dam deposit ( Esdale et al., 2003 ). The spatial...
