A joint effort between the U.S. Geological Survey’s (USGS) Global Desert Dust and NASA’s Stratospheric and Cosmic Dust Programs identified culturable microbes from an air sample collected at an altitude of 20,000 m. A total of 4 fungal (Penicillium sp.) and 71 bacteria colony-forming units (70 colonies of Bacillus luciferensis believed to have originated from a single cell collected at altitude...

Detailed geological mapping of the Urtier Valley in Western Alps allowed to realize a new map 1:10.000 scale. In mapped area, complete nappe stack axial part Alpine belt crops out. The study focused on two units derived from Piemonte-Ligurian oceanic domain, Broillot and Bardonney units, for which, addition classic petrographic structural considerations, lithostratigraphic approach was applied....

In the history of geology there have been two discoveries, plate tectonics and geological time, which have literally defined the way geologists view the earth. By geological time we mean the understanding that the universe has existed for countless millennia, such that man’s earthly dominion is confined to the last milliseconds of the metaphorical geological clock. The influence of geological t...

Introduction: The density of impact craters is widely used in planetary science to study relative and absolute surface ages and the nature of resurfacing on planets. On Venus, the applicability of such methods is very limited due to the small total number of impact craters (about a thousand) [1-3], which is caused both by shielding with a thick atmosphere and active volcanic/tectonic resurfacin...

Geological and geophysical studies in complex valley troughs provide a key record for the reconstruction of paleoenvironmental conditions during Quaternary. Here we present study sedimentary infill El Cervunal kame or trough (Sierra de Gredos, Iberian Central System) by means combined interpretation near-surface techniques supported geomorphological borehole data. A set 1D 2D methods, including...
