| 摘 要： | 山东省烟台市双山屯金矿产于牟平—朱吴断裂的构造破碎带中,与区域金矿的特征相似,金矿体严格受断裂的控制。深部的金矿体主要有Ⅱ-7号和M7号矿体,金矿体在空间上呈舒缓波状,并向E侧伏;断裂控制了围岩蚀变的范围、形态和分带,也控制着矿体的产状、形态,使蚀变和金矿化具有时空的一致性。勘查结果表明,深部的金矿体在产状、矿石类型等方面出现了明显变化,在-900m标高以下并未封闭,仍有向深部延伸的可能,因此要注意已知矿体边部和深部的找矿;控矿断裂在晚中生代经历了多次性质的活动,但金的成矿只是在断裂活动的特定时段发生,即早白垩世晚期(130~110 Ma)的张扭活动,该期断裂活动提供了成矿所需的运移通道和储矿空间。

| Abstract: | The gold deposit occurs in the cataclastic zone of Muping-Zhuwu fault with features of the re-gionally distributed gold deposits.Ore bodies are strictly controlled by fault.Ore bodyⅡ-7 and M7 are the main deep ore bodies.Spatially they look gentle wave and pitches to east.Extent,morphology and zoning of the wall rock alteration and attitude and change of the attitude etc.of ore bodies are generally controlled by faulting.Mineralization coincides with alteration.Attitude and ore types of ore bodies vary evidently to depth and are not closed bellow -900 m elevation and extend possibly to more depth thus at-tention should be paid to surroundings and depth of the known ore bodies for further exploration.During Late Palaeozoic Era nature of fault activity changed many times.However,gold ore was formed at special period of the faulting activity namely tenso-shear period when fault provides channel for ore fluid transpor-tation and space for ore precipitation. |
