Understanding the Nature of Collapsed Subsurface karsts: Analogues from the Tropical Karst Regions

Karst is a distinctive landform that results from the dissolution of carbonate rocks, and the dissolutional process is considered to be an important geologic phenomenon that may lead to the formation of karst reservoirs. The process of burial, compaction and diagenesis is believed to transform...

description Karst is a distinctive landform that results from the dissolution of carbonate rocks, and the dissolutional process is considered to be an important geologic phenomenon that may lead to the formation of karst reservoirs.

In order to comprehend the mechanism of formation and dimensional increment after burial, a tropical karst cave was surveyed and world largest passage caves were considered.

Moreover, because of the presence of immense speleothem deposits that typify tropical karst areas, we suggest that additional cave facies, i.e. massive to slightly fractured speleothems, to be included in the pre-existing paleocave facies classification.
