| 摘 要： | 铜山口铜(钼)矿床位于湖北省大冶市境内,是一典型的矽卡岩-斑岩复合型矿床。通过对其流体包裹体的系统研究,确定了成矿阶段成矿流体的成分及温压条件,并结合矿床学研究,将成矿过程分解为两个平行的成矿阶段,即矽卡岩型矿化阶段和斑岩型矿化阶段。根据Johson和Reed等人建立的水 岩反应模型,对本矿床成矿流体与围岩反应并析出金属沉淀的过程进行了数值模拟计算,其结果与实际地质情况吻合较好。 |

NUMERICAL MODELING ON WATER-ROCK INTERACTION OF ORE FLUID OF TONGSHANKOU Cu(Mo) DEPOSIT |
|
| Abstract: | The Tongshankou Cu(Mo) deposit,located in Daye City,Hebei Province,is a typical skarn porphyry compound deposit. The composition, temperature and pressure of ore fluid were determined according to systematic research on fluid inclusions. Combined with deposit geology, mineralization was divided into two parallel stages, the skarn mineralization stage and the porphyry mineralization stage. By using the equilibrium model of water rock interaction established by Johson and Reed et al., the paper puts forward the geochemical model of interaction between ore fluid and wall rocks with convincing simulating results in coincidency with geological phenomena. |
| Keywords: | ore fluid water-rock interaction numerical modeling skarn-porphyry compound Cu(Mo) deposit Tongshankou |
