| 摘 要： | 北淮阳构造带东段含矿角砾岩主要有全筒矿化型和复合矿化型两种,前者与浅成岩有一定距离,后者在空间上与浅成岩伴生.两种类型含矿角砾岩的角砾、胶结物成分存在差异,但产出状态、岩石化学、同位素等分析均表明,岩浆隐蔽爆破作用是受浅部流体的生成方式、区域构造应力和岩浆热动力的联合作用控制的,这一规律为该带的找矿工作指明了方向.

| Abstract: | Ore-bearing breccias can be divided into complete-pipe and compound mineralizing types in the east part of north Huaiyang tectonic zone, in which the former type keeps certain distance from the hypabyssal rock, the latter one is accompanied by the hypabyssal rock in space. Although there exist differences among breccia and cement, analysis results of occurrence, chemical composition and isotope suggest that magma crypto explosion causes crypto fluids. The forming of breccias is controlled by regional tectonic stress and magma thermodynamics. This role points out polymetallic deposit's prospect direction. |
