摘要
葛泉岩溶陷落柱非常发育且具有明显分布特征和规律:密集成群性、网络带状分布性、似等距分布性、构造控制性。多数陷落柱顶部发育到石盒子地层、发育下限为中奥陶统灰岩最下部含膏层。靠近向斜轴线的部位,特别是复向斜反"S"构造的转折部位并受到断层切割,是陷落柱发育的有利部位。
The Paleo-sinkholes in Gequan mine developed very well, and had obvious distributing rules which are denseness in group, network strip distribution, approximately equidistant distribution, tectonic controlled. The top of most Paleo-sinkholes developed up to Shihezi strata and the base down to 02 limestone strata. The places near syncline axes, especially multiple syncline tansition cut by faults, are favorable for Paleo-sinkholes development.
