Devonian rocks are exposed in every region of Thailand, commonly occurring in thick sequences of Lower to Upper Palaeozoic sedimentary and volcanic rocks (Fig. 4.1). However, a scarcity of marker fossils and generally discontinuous exposures have meant that Devonian rocks are frequently not distinguishable from older and younger rocks. In such cases, the Department of Mineral Resources (the DMR) have inferred Devonian rocks to be present and have mapped them as Silurian-Devonian, Silurian-Carboniferous, or Devonian-Carboniferous (DMR 1999).

The Geology of Thailand
This is the first volume in the English language to cover the entire range of the geology of Thailand since the joint Thai—US account by Brown et al. exactly 60 years ago. Over this period there has been a phenomenal growth in interest in this core area of SE Asia. This has been led by geologists in Thailand, but with important and highly significant input from geologists based elsewhere in Asia and in Europe, Australasia and North America. Some of that research was prompted by commercial considerations, since Thailand has important energy and mineral resources, while other research has sought to understand better the stratigraphic and structural history, including the plate-tectonic story which Thailand's rocks reveal. This new volume seeks to bring together all of this knowledge into a single accessible book; it is the work of an international team drawn from Thailand, Japan, Australia, USA, Canada, Germany and the UK.
