Geochronological constraints on the age of a Permo-Triassic impact event: U-Pb and Ar-40/Ar-39 results for the 40 km Araguainha structure of central Brazil
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
Impact cratering has been a fundamental geological process in Earth history with major ramifications for the biosphere. The complexity of shocked and melted rocks within impact structures presents difficulties for accurate ...

(Elsevier Science, 2013-11-28)
Soil temperatures of the active Volcanic Complex Peteroa situated in the Cordillera Principal between Chile and Argentina at 35°15′ S and 70°35′ W (approximately) were monitored in the area, and local geomorphology ...
Ground-Based Observational Techniques for Meteoroid Lunar Impact Generated Electromagnetic Pulses and Lunar Sub-Surface Structure Detection
(The Pennsylvania State University, 2017-08)
The lunar surface is pockmarked with large and small craters mostly formed due to meteoroid impacts on the Moon. Most of the craters formed are not erased with time due to lack of "weathering" processes such as no atmosphere ...
