Mazantic slate
Mazantic Shale (English: Mazantic Shale;) is an amber- bearing slate that was formed in the Neogene period . It belongs to the formation of the Chiapas Thrust-Fold Belt (Central & Eastern Thrust-fold Belt) in Mexico and is characterized by a large number of insect fossils ( Chiapas amber ).
The slate comes in the area of Simojovel in Chiapas , southwestern Mexico before. It is accessible, for example, in the Totalapa Amber Bearing Beds . It is assumed that the deposits originated in the Miocene , especially in the sections of the Burdigalium (21-16 million years ago). Mollusks and arthropod inclusions in amber, as well as lignite, indicate that the deposits are continental.
The Mazantic schist is overlaid by Balumtum sandstone .
