Abstract | The Cenozoic Doi Ton Formation is outstanding for its leaf fossil deposited in sandstone of which the geologic age isstill controversial. This research focuses on stratigraphy and sedimentary facies analyses in order to interpret thepaleoenvironment, paleoclimate and identify the geologic age of the study area. Doi Ton Formation can be divided into upper andlower members. The upper Doi Ton member can be divided into five facies including, Sm, Sg, Sr, Sp, and Gm (Gm and Gmg).Furthermore, these facies make up two facies associations, which are (1) channel deposit (Gm, Gmg, Sg, Sr, Sp, and Sm), and (2)sandy bar (Sg, Sr, and Sp) indicating the braided river depositional environment. The lower member is mainly composed ofmudstone that suggests the low energy environment. The mineral compositions and leaf fossils indicate the warm and humidclimatic conditions during their deposition period. |
