A case for short duration of Deccan Trap Eruption

Authors


Abstract

Earth's geologic past has been punctuated by episodes of voluminous outpouring of lava that flooded large areas of continents and oceans, giving rise to what are commonly called flood basalt provinces. These flood basalt eruptions often coincided with major stratigraphic boundaries and mass extinction events.

The Deccan Traps of India are a muchstudied example of a flood basalt province that erupted at or near the Cretaceous/Tertiary (K/T) boundary 65 million years ago. These lavas reach a maximum thickness of 2.7 kilometers at the Western Ghats of India.
