Fig. 2From: Geologic framework of the Fang Hot Springs area with emphasis on structure, hydrology, and geothermal development, Chiang Mai Province, northern ThailandGeologic map of the Fang Basin area from von Braun and Hahn (1981) showing location of Fang Hot Springs. Formation names from Imsamut and Krawchan (2005) and the Thailand Department of Mineral Resources (2013). We recognize that mapping since 1981 has somewhat changed the outcrop areas and assigned ages. Solid lines are faults related to Fang geothermal area, dotted lines are subsurface faults mapped by Kongmongkhol and Chantraprasert (2015). Symbols explained in Fig. 3Back to article page
