摘要
老挝的煤炭资源以褐煤为主,烟煤次之。烟煤的含煤地层为石炭系乍奎组(Cz)、中二叠统南康尚组(P2nk)、上三叠统。褐煤产于新近系中。煤炭资源主要分布在沙拉湾(Saravane)石炭系烟煤成矿远景区,万荣(Vang Vieng)中二叠统烟煤成矿远景区,丰沙里(Phong Saly)-孟赛(Muang Xay)上三叠统烟煤成矿远景区,南塔(Nam Tha)新近系褐煤成矿远景区,桑怒(Xam Nua)-孟佩(Muang Pek)中新统褐煤成矿远景区。
Coal resources in the Laos are mainly lignite in rank and bituminous coal the second. Coal-bearing strata of bituminous coal have Carboniferous Za Kua Formation （Cz）and Middle Permian Series Nam Kangxang Formation （P2nk）, and Upper Triassic Series. Lignite is in the Neogene System. Coal resources are mainly distributed in the Saravane Carboniferous System bituminous coal deposit-forming prospect, the Vang Vieng Middle Permian Series bituminous coal deposit-forming prospect, the Phong Saly-Muang Xay Upper Triassic Series bituminous coal deposit-forming prospect, the Nam Tha Neogene System lignite deposit-forming prospect and the Xam Nua-Muang Pek Miocene Series lignite deposit-forming prospect.
