| 摘 要： | 通过对刘家坡金矿的成矿地质特征、金矿化特征、控矿因素、成因的综合分析研究认为，刘家坡金矿是一种新的微细浸染型和构造角砾岩型金矿化。受下石炭统沉凝灰岩、不纯灰岩层及桃圆——云Bing寺区域断裂控制，而矿体直接产于层间构造破碎带与舍矿构造复合地段。此外，岩浆活动、热液蚀变对金成矿也起着极为重要的作用。 |
| 关 键 词： | 刘家坡金矿 沉凝灰岩 金矿化特征 控矿因素 成因 |

| Abstract: | On the basic of synthetic analysis of the geocharacteristic of gold ore formation, features of mineralization, factors controlling ore formation, cause of formation of gold ore in Liujiapo,we think it is a mixed mineralization of micro-dissemination and tectonic breccia, and is affected by sedimentary tuff, impure limestone in lower Carboniferous and areal fracture in Taoyuan-Yunbinsi. The orebody is in fracture zone mixed with zone of pay structure. In addition, magmatic activity and hydrothermal alteration play an important role in gold deposit. |
| Keywords: | gold ore in Liujiapo sedimentary tuff features of mineralization factors controlling ore formation cause of formation |
