Map of South and Southeast Asia showing the distribution of ultramafic outcrops in the region. Bottom inset is a more detailed outline of ultramafic outcrops in Borneo, Palawan, Mindanao, Sulawesi, and Halmahera. Not all regions of India have complete geologic surveys, and we were unable to locate precise information about ultramafic outcrops in Burma and Laos. The ultramafic outcrop location in Northern Thailand is approximate. The extent of each outcrop shown is not to scale
