| 中文摘要: |
| 黑龙江黑龙宫地区地表43个不同性质蚀变岩石δ18O值从-2.2‰到11.5‰,勾画出一个中心高18O带和周围低18O带。结合该地区地质特征以及已知氧同位素勘查模型,推断黑龙宫地区具三层圈18O带多中心水-岩交换的成矿地区,隐伏矿体可能位于中心高18O带。 |
| 英文摘要: |
| A systematic 2-dimentional mapping of oxygen isotope compositions have been carried out for the altered wall-rocks of Heilonggong copper prospect, Shanzhi Count, Heilongjiang, and a high-low-high δ18O system has been discriminated indicating the Heilonggong copper prospect as a high-low-high δ18O system of porphyry or (and) skarn type Cu/Mo (zhang et al,1993a,1994a, 1995c). The best prospecting area should be the central high-18O scope and the contact zone of in the eastern part. A NE trend low-18O zone (δ18O= 0-2‰) in the north-west is the second best area. |
