摘要
通过对建德铜矿床调查研究,总结矿床成矿条件,分析控矿因素,探索矿体分布规律,确定岩浆热液成因后,提出矿液运移理论,首次运用计算机进行数学物理模拟和深部成矿预测,已均被证实,表明所采用理论、方法的合理性和正确性。因矿区发现少量火山岩和硅质岩等而提出海底火山热液沉积成因,经近年矿区地质特征、成矿年龄和流体包裹体等详细研究和开采勘查,认为该矿床为岩浆热液成因,并据此在该矿床外围找到类似的高岭铜矿床。随着矿床研究的深入,在矿床地质特征、成矿时代、成矿流体和成矿物质来源等取得了新进展,矿床成因和成矿机制也因此得到进一步验证。
Jiande copper deposit was discovered in 1958.It was explored by the geological department and mined by the metallurgical department in 1960.By 1980,when the reserves handed over were about to be mined out and became a critical mine,the author was invited to take a group of teachers and students to investigate and study the ore deposit,summarize the ore-forming conditions,analyze the orecontrolling factors,explore the ore-body distribution law,and determine the origin of magmatic hydrothermal fluid.The theory of ore liquid migration was put forward.The mathematical and physical simulation was carried out by computer for the first time.It shows the rationality and correctness of the theory and method adopted.Because a few volcanic rocks and siliceous rocks were found in the mining area,the genesis of submarine volcanic hydrothermal deposits was proposed.Based on the detailed study and exploration of geological characteristics,metallogenic age and fluid inclusions in the mining area in recent years,the deposit is denied to be the origin of submarine volcanic hydrothermal deposit,which is further confirmed to be magmatic hydrothermal genesis.A similar Gaoling copper deposit was found on the periphery of the deposit.
