Abstract
The limestones at Hang Cay Ot, Binh An commune, Ha Tien district, Kien Giang province belong to Ha Tien formation (Middle Permian). Based on microscopic studies, the limestones at Hang Cay Ot are packstone, grainstone and wackstone according to the Dunham carbonate rock’s classification, and four microfacies types are recognized. As a result, according to the modified Wilson model, three facies zones have been differentiated: (1) open marine platform interior zone, (2) platform-marin and shoal zone, (3) platform-marin reefs zone.
