| 摘 要： | 浙江建德块状硫化物矿床，以Cu＞Zn＞Ph为特征。鉴于Cu、Ph和Zn三元素的地球化学行为和海底喷流作用的固有特性，它们在横向上和纵向上均具独特的分带性，显示出旋回结构。对黄铁矿中特征元素元素比值、成矿温度以及铅同位素组成等方面的研究表明，该矿床乃同生沉积作用的产物，而非岩浆热液成矿。

| Abstract: | The Jiande massive sulfide deposit in Zhejiang Province is characterized by Cu > Zn>Pb in composition. Because of geochemical characteristics and inherent properties of submarine exhalati0n, CuPb-Zn zonation is obvious in the horizontal and vertical directions, indicative of cyclical sedimentation.Through the study on trace elements and their typical ratios, ore-forming temperature and lead isotopic composition, the authors conclude that the ore deposit was actually formed in a syndeposition environment. There is no sign to show that the deposit is associated with magmatic hydrothermalism. |
