中文摘要：

内蒙古小坝梁矿床是大兴安岭中南段的一个中型Cu-Au多金属矿床,通过对矿床地质特征、二叠世海相火山岩、热水沉积岩、层控特征以及同沉积断裂的系统研究,认为小坝梁矿床在二叠纪沉积盆地演化过程中可能曾经有重要的喷流-沉积成矿作用发生。

英文摘要：

The Xiaobaliang deposit, Inner Mongolia Autonomous Region, is a middle scale Cu-Au deposit in the southern section of DaXing＇ anling Mountains. By studying the geological characteristics, the Permian marine volcanic rocks, hydrothermal sedimentary rocks, the strata-bound characteristics of the Permian strata and syndepositional fault of the Xiaobaliang deposit, the authors demonstrate that exhalative-sedimentary mineralization occured during the basin evolution at the Permian time in the Xiaobaliang deposit.
