摘要
矿体赋存于下奥陶统多泉山组中,矿石类型为泥晶灰岩和含生物碎屑泥晶灰岩,典型的残海生物化学沉积,含CaCO393.69ω%～94.0ω%,理想的制碱石灰岩,受地层控制,矿体稳定易采。
The ore body is in Lower Ordovician Duoquanshan Formation. The ore type is argillo -crystalline limestone and bioclast - bearing argillo - crystalline, which are the typical epicontinental biochemical sedimentat with CaCO3 93.69ω% - 94.03ω%. It is the ideal soda - making limestone controlled by the strata. The ore body is stable and exploited easy.
