Evidence of extensive lunar crust formation in impact melt sheets 4,330 Myr ago
Accurately constraining the formation and evolution of the lunar magnesian suite is key to understanding the earliest periods of magmatic crustal building that followed accretion and primordial differentiation of the Moon. However, the origin and evolution ...
2020Redox variations and bioproductivity in the Ediacaran: Evidence from inorganic and organic geochemistry of the Corumba Group, Brazil
Stable isotope ratios combined with elemental compositions and molecular biomass data provide a powerful tool in Neoproterozoic palaeoenvironmental interpretations. Here, we report the results of an extensive organic and inorganic geochemical study perform ...
Elsevier2014Active Sites in HZSM-5 with Low Fe-content for the Formation of Surface Oxygen by Decomposing N2O: Is Every Deposited Oxygen Active?
Surface-active centers were detected in HZSM-5 with a low content of iron (
2003Meteorite stranding surfaces and the Greenland icesheet
Thirty years of recoveries in East Antarctica have led to significant understanding of the regional characteristics associated with meteorite stranding surfaces. In Antarctica these sites are characterized by patches of snow-free blue ice at high altitude ...
2001Formation of sugar phosphates under potentially natural conditions
In studies related to the origin of life on Earth, the authors considered the geochem. conditions for the formation of tetrose-, pentose-, and hexose phosphates in the Archean. Some of the reactions depend on bilateral surface active minerals for concn. an ...
