Preliminary Study on Geology of Khwekha-Helok Area, Kalay and Falam Townships
- The study area is situated on the eastern flanks of the Chin Hills, about 20 km southwest of Kalaymyo. This area is generally trending SEE-NWW forming a north-south dipping isoclinals structure. In the study are, there are two main rock units are exposed; metasedimentary rocks and igneous rocks. Among the metasedimentary rocks, the schist unit is dominant that are quartz-rubellite schist, quartz-mica schist, hornblende schist, hornblende-epidote schist. The quartzite is exposed as a minor amount. These metasedimentary rocks are dated as Upper Triassic or older and probably derived from the ophiolite rock suite (basic and pellitic rocks). The igneous rocks units are mainly ultramafic rocks that comprise serpentinite, harzburgite and dunite. These ultramafic rocks intrude the metasedimnetary rocks and the age of intrusion may be late Cretaceous.
