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).

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 ...

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 ...

"Our team has analyzed all the relevant fossils and geological strata of the Triassic in southern Germany and other parts of Europe for this important project, combining different research approaches.

MODERN geological research has rendered it almost ... those contortions of rocky strata many thousands of feet thick, those upheavals of mountain-chains and that elaborate modelling of the surface ...
