Lithology and Thickness
Ashangi Basalt Fm:
LITHOLOGY = Analagous to Ethiopian flood basalts or ‘‘trap series’’? This sequence attained a preserved thickness of 2 km and presently covers an area of 0.6 million km2 (Mohr, 1983b; Zanettin, 1993). Prior to erosion, the total thickness of the volcanics was 4 km and they covered a much larger area.
CALIBRATION = Placed in the Base of the Eocene for display purposes.
