Abstract
The Tha Takiap area is a part of the Eastern Granitic Belt which is widely ranging in composition from gabbro to granite rock, and also located on the Sukhothai Arc. Nine representative diamond drill core samples of the alkaline granitic rock from the Tha Takiap area are collected for
petrographic and geochemistry analysis. Based on the petrographic study, the alkaline granitic rocks composed mainly of K-feldspar with minor amounts of quartz and plagioclase that were classified as alkali feldspar syenite to alkali feldspar quartz syenite according to QAPF diagram. Geochemical data of major oxides indicate that the rocks from the study area are alkaline syenite and classified as metaluminous. Trace elements and REE indicate that the alkaline granitic rocks are A2 subtype of A-type granite. The samples from the Tha Takiap area show the depletion of some large ion lithophile elements (LILE) (Ba, Sr and Eu) and Ti that may reflect fractionational processes of plagioclase and/or feldspar and titanomagnetite. Nearly flat REE patterns might refer to mantlederived magmatic source more than arc-derived magmatic source. In the comparison of geochemical data, the Tha Takiap granitic rocks show the distinct trace element and REE patterns to the alkaline granitic rock of Eastern Granitic Belt in Malaysia Peninsular. In contrast, similar trace element and REE patterns of the Tha Takiap granitic rocks have been observed in Xiaolonghe A-type granite of the Tenchong-Lianghe tin belt, southwestern China, which is interpreted to have formed under backarc extensional setting. Therefore, the Tha Takiap alkaline granitic rocks possibly formed by backarc extension related, and it is indicated that magma responsible for the ophiolite along the Sa Kaeo Suture has close tectonic (back-arc extension) and temporal (Late Permian) link to the alkaline magma at the Tha Takiap area
