that geological strata associated with these changed conditions are "distinct from Holocene strata"; and that the plutonium concentrations from the stratotype section at Crawford Lake, Canada has ...

A new epoch would mean that a distinct change could be seen in the fossil record with geological strata distinctive from those below and above it. Zalasiewicz is convinced that the Anthropocene ...

This is the principle of cross-cutting relationships. The principle states that any geologic features that cut across strata must have formed after the rocks they cut through (Figures 2 and 3).

It was through a letter dated March 30, 1579 that Giovanni Arduino announced the four orders that form the basis of ...

A University of Tokyo research team says it has succeeded in collecting microorganisms from two-billion-year-old geological strata in South Africa that may still be alive. If confirmed ...

Smith's colourful and sophisticated geological map was based on his astute observation that rock layers (strata) could be identified by the fossils they contain. He noticed that the layers always ...
