THE DEPOSITIONAL ENVIRONMENTS IN THE REGION OF AN HA CANAL BINH CHANH DISTRICT HOCHIMINH CITY, IN LATE PLEISTOCENE - HOLOCENE AND RELATED MINERAL RESOURCES

Abstract

While searching and exploring for mineral resources in the region of An Hạ canal, authors have done hundreds of shallow and deep boreholes. Some minerals such as peat, clay, pebble and ground-water have been discovered. These are materials of ancient sedimentary environment deposited during thousands of years ago. Analysing sedimentary structures of boreholes associated with other methods, authors reconstructed ancient sedimentary environments of this region. Sedimentary environments belong to the Holocene and Pleistocene ages are basically cleared up. This is a basic method to define environment, especially in non-fossiliferous ones.
