Focused geoscience search
4Geology is a search engine built for people who work in or study the earth sciences. It combines multiple search indexes, specialist algorithms, and AI systems to surface geology-specific results -- from peer-reviewed papers and geologic maps to datasets, tools, and suppliers. Use targeted filters to find maps, reports, field equipment, or technical guides with relevance tuned to geological terminology and practice. Part of the 4SEARCH network of topic specific search engines.

Inside Mercury’s Raditladi and Eminescu craters, MESSENGER images revealed glacier-like flows that may consist of salts and other volatile-rich material preserved for more than a billion years—raising the possibility of buried niches analogous to salt deposits inhabited by extremophiles in Earth’s Atacama Desert.
21+ hour, 40+ min ago (1157+ words) MESSENGER mapped glacier-like runouts and hollows in two Mercury craters; salt-flow models explain their form and longevity, but neither composition nor habitability has been demonstrated....
