摘要
对金沙江溪洛渡电站区二叠系下统（Ｐ１）灰岩岩溶发育规律综合研究后发现：本区内的岩溶洼地多为“半边岩溶洼地”；岩溶漏斗四周为玄武岩碎块的“特殊类型岩溶漏斗”；
The comprehesive studies of developed rules of P 1 limstone karst in the region of hydro electric power station in Xiluodu, Jinsha river revealed that the lakes distributing at 1100￣1200m a.s.l. were developed along bedding strikes, most of the karst depressions are “one side depressions”, and the karst dolines are the “special types” covered with basalt. The special karst shapes are formed by dissolution and corrosion of carbonate rocks and collapses under the control of bedded rock structure and neotectonic movement, not by glaciation.
