The Quaternary Stratigraphy in the Northern Basin of the Central Plain, Thailand

Abstract

TAKAYA proposed a Quaternary stratigraphy for the Central Plain of Thailand based on his observation of natural outcrops (TAKAYA, 1968). During field survey, he paid special attention to the relationship between the degree of weathering and stratigraphical position. To examine the relationship in more detail, the author made a field survey and sample collection with the help of TAKAYA during the period from November, 1968 to January, 1969. In this report, the result of the field survey and subsequent laboratory work is presented. A proposal concerning a new formation is also made which modifies TAKAYA's stratigraphy.
