The geology of Thailand is diverse, reflecting its complex tectonic history. The country lies at the confluence of three major tectonic plates: the Eurasian, Indo-Australian, and Pacific plates. This has resulted in a mix of geological features, including ancient Precambrian rocks, Paleozoic sedimentary formations, Mesozoic volcanic arcs, and Cenozoic sedimentary basins.
Northern Thailand features mountainous terrains with metamorphic and igneous rocks, while central and southern regions are dominated by sedimentary basins and karst landscapes formed from limestone. Thailand is also rich in mineral resources, including tin, tungsten, and gemstones, making geology integral to its economic development.
