Balumtum sandstone
Balumtum sandstone is an amber- bearing sandstone that was created 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 sandstone 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 Langhium and Burdigalium sections ( 21-13 million years ago). The structure is tightly packed and heavily "cemented". Mollusks and insect and arthropod inclusions in amber, as well as lignite, indicate that the deposits are continental.
The Balumtum sandstone rests on the Mazantic slate and is overlaid by Santo Domingo sandstone .
