Learn More About Geoarea of the Barito Basin and Asem-Asem Basin
Within the Meratus Mountain Geopark region, there is a geoarea distribution consisting of: Geoarea of the Meratus Mountains, Geoarea of the Barito Basin and Geoarea of the Asem-Asem Basin. This time I will discuss a little more about the Geoarea of the Barito Basin and Geoarea of the Asem-Asem Basin.
Both geoareas have geosites dominated by various landscapes, karst caves and hot springs. Each geosite is formed with different rock formations with an estimated age which is also different from what is found in the Meratus Mountains Geoarea.
Geoarea Barito Basin
In the Geoarea of the Barito Basin there are 15 geosites which mostly consist of caves and landscapes with different formations.

Bukit Kayangan has Dahor Formation which is Late Miocene – Pliocene (1.8-11.2 million years ago).
Geoarea Asem-asem Basin
Georea The Asem-asem Basin does not have many geosites but is still worth visiting because of its unique nature in the form of karst caves.
The Liang Bangkai Cave has an Oligocene – Early Miocene (16-36.5 million years ago) Berai formation.
Liang Udud Cave has the Oligocene – Early Miocene (16-36.5 million years ago) Berai formation.
The struggle of Hasan Basri Cave and several archaeological sites has the Oligocene – Early Miocene (16-36.5 million years ago) Berai formation.
