High-resolution seismic reflection techniques successfully imaged structural features associated with a sinkhole that formed catastrophically as a result of dissolution of the Permian-age Hutchinson Salt in central Kansas. Symmetric steep sided chimney structure formed instantaneously, which over time has continued to gradually enlarge and elongate to the east, forming an open bowl. Orthogonal ...

Abstract. Paleoclimate archives, such as high-resolution ice core records, provide a means to investigate past climate variability. Until recently, the Law Dome (Dome Summit South site) record remained one of few millennial-length coastal records in East Antarctica. A new drilled 2017/2018 at Mount Brown South, approximately 1000 km west Dome, provides an additional that will likely span last m...

the most enigmatic problems with the nearly 200 salt domes pierced in the persian gulf and in the zagros mountain ranges (zmr) in southern iran, a unique morphology in the world, have been the matter of this study, which is based on a combination of field work, enhancement of satellite and aerial photographs etc. in the zmr, structural anomalies are frequently associated with similar facies dis...

A record of Pb isotopic compositions and Pb and Ba concentrations are presented for the EPICA Dome C ice core covering the past 220 ky, indicating the characteristics of dust and volcanic Pb deposition in central East Antarctica. Lead isotopic compositions are also reported in a suite of soil and loess samples from the Southern Hemisphere (Australia, Southern Africa, Southern South America, New...

Ice core glaciochemical records provide detailed information on past changes in atmospheric chemical composition and circulation, which is essential for understanding the timing and phasing of climatic change in different regions. Atmospheric circulation reconstructions based on these records require knowledge of modern chemical concentration controls (chemical source, transport pathway and str...
