Nga Chang Supergroup Gr

Synonym: กลุม่หินสตูล

[Figure: Approximate correlation of measured sections within the Nga Chang Supergroup in Lower Peninsular Thailand. (a) Laem Thap in Nakhon Sithammarat Province (based on Lumjuan, 1993); (b) Laem Thap, same as ‘a’ (based on Chaodumrong et al., 2007); (c) Ko Phi Phi in Krabi Province (after Waterhouse, 1982); (d) Ko Muk in Trang Province (after Waterhouse, 1982); (e) Ban Kan Rae in Songkhla Province (after Fujikawa et al., 2005); (f) Thung Wa–Langu road in Satun Province (after Wongwanich et al., 2002); (g) and (h) Khuan Khi Ma and Khuan Sung in Satun Province (see Fig. 5; after DMR, 2004); (i) Pulau Ular, Langkawi, Malaysia (after Stauffer and Lee, 1986). The vertical relationship of one section to another is speculative and so therefore is the total thicknesses of the Kaeng Krachan Gr (Ridd. 2009).]

See lithology in each individual formation/group. (The Lower Ordovician-Lower Devonian Satun Gr, the Devonian Pa Samed Fm, the Carboniferous Khuan Klang Fm and the ?Carboniferous–Lower Permian Kaeng Krachan Gr).
