Abstract

This review of the granites of Thailand is based on the work by Cobbing et al. (1986, 1992), Charusiri et al. (1993) and subsequent studies (Charusiri et al. 2002; Putthapiban 2002). The term granite is used throughout in its broad sense meaning a felsic plutonic rock, and covers compositional varieties including adamellites, tonalities and granodiorites among others, as well as granites sensu stricto. Recognition of the different Granite Provinces and the tectonic divisions in Thailand was facilitated by the description of similar belts of granites and tectonic divisions in SE Asia by Mitchell (1977) and along-strike to the south in Peninsular Malaysia by Hutchison (1977). Each Granite Province is characterized by distinctive batholiths, plutons, stocks, pegmatites and units repre senting different granite types and ages of emplacement. The nomenclature of the Granite Provinces in SE Asia present in Thai land is based on that of Hutchison (2007); the granites of Thailand (Fig. 16.1) are distributed in three Granite Provinces comprising a Western, Eastern and a Central Province that form approximately linear north-south belts.

The Western Province is of largely Cretaceous age but extend ing locally to the Palaeocene. The Eastern and Central Provinces, on the other hand, are of Triassic age.

The Western Province occupies Upper Peninsular Thailand passing west into Myanmar, and to the south it reappears across the Malacca Straits in Sumatra. The Eastern Province runs from western and north-western
