Thái Bá Ngọc
The existence
of sandstones, limestones with karst caves and fractured igneous rocks is important reservoirs for
Petroleum geology. Tri Tôn (An Giang province), Hà Tiên, and Ḥn Đất
(Kiên Giang province) are regarded as ideal places of field trip for students from the
Department of Petroleum, Faculty of Petroleum Engineering and Geology, Hồ
Chí Minh City University of Technology. Based on geological data, the authors
present the Pre-Cenozoic geological units in the study area including Devonian
terrigenous sediments (Ḥn Heo Formation), Permian limestones (Hà Tiên
Formation), Triassic felsic volcanic rocks and their tuffs with minor
associated terrigenous (Ḥn Ngang Formation), the Upper Triassic - Lower to
Middle Jurassic' terrestrial deposits (Tà Pa Formation) as well as the
Cretaceous igneous rocks (Định Quán and Đèo Cả intrusive
