Required Geological Setting

Neogene and Quaternary sediments


Copal, a kind of fossil of resins associated with lignite. As copal is not subjected to enough diagenesis in Neogene to Quaternary sediments, it is not so matured as amber. Copal is easily weathered in the air to be clouded or powdered. Copal is observed on the lignite of tree trunks and branches, and also in the same stratigraphic horizons of lignite.


Distribution of copal described in this site. Yellow is Neogene and Quaternary sediments.
