| 中文摘要: |
| 桦树沟铜矿生成于陆缘海的断陷盆地,容矿岩系为热水沉积硅质岩。其矿石的结构构造、空间分布,矿物组合及化学成分、稳定同位素及成矿温度等12个成因参数特征,均表明条带状纹层状铜矿石形成于海底喷气-热液沉积成矿作用。而角砾状碧玉黄铜矿矿石是由加里东晚期造山运动产生的变质热液充填交代碧玉岩角砾所成。铜矿体不仅局限于向斜的NE翼,在其SW翼和向斜向NW的延长部分找矿是有希望的。 |
| 英文摘要: |
| Huashugou Cu deposit was formed in the fault basin of a continent marginal ocean. The host rock is the siliceous rock deposited by hot water.It is discreminated by 12 parameters of ore structure and texture, spacial distribution, mineral assemblages and chemical composition,etc that banded ore and laminae ore are formed bybmarine exhalation hydrothermal sedimentation.Breccia jasper chalcopyrite ore is formed by filling replacement of jasper breccia by metamorphic hydrothermal fluid during the late calidonian period. Cu ore is not only limited in NE limb. Exploration should be added to the extension parts of the SW and NW Limbs of the ore-comtroling fold. |
