From Wikipedia, the free encyclopedia
The Chasicoan (
Spanish : Chasiquense or
Spanish : Chasicoense ) age is a period of
geologic time from 10–9
Ma within the
Late Miocene epoch of the
Neogene , used more specifically within the
SALMA classification in South America. It follows the
Mayoan and precedes the
Huayquerian age.
[1]
The Chasicoan is named after the
Arroyo Chasicó Formation of the
Colorado Basin in northeastern Argentina.
