甘南在加里东运动后,地壳的波浪凹陷转移到加里东褶皱带以北,形成了从中泥盆世到中三叠世的沉积坳陷带。甘肃的铅锌矿的基础是中泥盆统地层的沉积作用。波浪状镶嵌构造又是铅锌矿形成的构造条件,它决定着铅锌矿的迁移,也控制着矿的富集。而沉积地层的形成及其与构造运动发展的统一和相辅相成正是今后找矿的前提。
After the Caledonian movement in Gannan, the wave depression in the crust shifted to the north of the Caledonian fold belt, forming a sedimentary depression belt from the Middle Devonian to the Middle Triassic. The foundation of the lead-zinc mine in Gansu is the sedimentation of the Middle Devonian strata. Wavy mosaic structure is the formation of lead-zinc tectonic conditions, which determine the lead-zinc migration, but also control the enrichment of ore. The formation of sedimentary strata and its unification and complementarity with the development of tectonic movement are the prerequisites for prospecting in the future.
