Long Lava Flows May Have Taken Years, Causing Global Cooling And Extinctions

Date:
October 28, 1998

American Geophysical Union
Summary:
A multidisciplinary group of scientists is challenging the century old theory that long lava flows must be formed by massive, but short lived, volcanic eruptions. Their research, reported in the Journal of Geophysical Research, suggests that some ancient flows of up to 100 miles in length built up gradually over years, rather than quickly in just days. This finding could have broad implications for the study of Earth and nearby planets.
