Alamo impact crater: New study could double its size

23 enero 2015

Carbonate rock deposits found within the mountain ranges of south-central Nevada, USA, record evidence of a catastrophic impact event known as the Alamo impact. This event occurred roughly 382 million years ago when the ancient seafloor was struck and a submarine crater was formed. The crater was filled-in with fragmented rock, and later with more typical ocean deposits, as the energy from the impact lessened and the environment returned to normal.
