| 中文摘要: |
| 浙江临安西天目地区地处早古生代扬子被动陆缘和晚中生代西太平洋活动陆缘构造叠加区域。该区发育碳酸盐岩建造，有大量的脉岩岀露，环形、放射状断裂构造发育，具有面型蚀变及铜、铅、锌、金等多个矿（化）点；重磁等物探信息显示，该区深部发育EW向深断裂和隐伏岩体；化探扫面揭示，区内钨、钼、铋、铜、铅、锌、金、银、砷等元素背景高；自然重砂调查反映，白钨矿、铅族、钼族等重砂矿物组合具有异常显示。综合成矿地质条件及物、化、重砂异常等信息，认为该区具有寻找斑岩型、夕卡岩型、低温热液型钨、钼、铜、铅锌、金银等多位一体矿床的潜力。 |
| 英文摘要: |
| The Xitianmu area of Lin'an district, Zhejiang province is located at locality where the Early Paleozoic Yangtze passive continental margin and the late Mesozoic West pacific active continental margin are superimposed. Carbonate rock formation is developed and many dykes are exposed. Ring fracture and radial fracture are also developed, Areal alteration and Cu, Pb, Zn ore and mineralization occurrences have been discovered. The information of the gravity and magnetic survey shows that the deep east-west fractures and concealed intrusive rock bodies occur in the area. Coverage of geochemical survey shows that W, Mo, Bi, Cu, Pb, Zn, Au, Ag, As are in a high background value. The heavy mineral survey reveals anomly heavy mineral combination of scheelite and molybdenum family and lead family element. According to the integrated information of the metallogenic condition, the geophysical and the geochemical survey, this area is potential for exploration of porphyry Cu deposits and skarn and epithermal W, Mo, Cu, Pb, Zn, Au, Ag deposits. |
