序言自60年代初内华达西北部卡林金矿被发现以来,浸染型金矿已成为重要的勘探对象.所谓浸染型金矿是指那些达工业储量的、金呈浸染状分散在各种成分岩石中的热液成因金矿床.由于该类矿床的规模、品位、结构构造、矿物共生组合、构造控制的性质与程度、容矿岩石的成分、与火成岩的关系、蚀变特征和程度以及其它因素变化较大,以致很难对该类矿床作更精确的定义.基于上述原因,加上金及其它伴生矿物的粒度细(主要为亚显微或显微大小)和难
Preface Since the discovery of the Carlin gold mine in the northwestern Nevada in the early 1960’s, disseminated gold has become an important target for exploration, and the so-called disseminated gold mine refers to those that reach industrial reserves with disseminated gold in various compositional rocks Due to the size, grade, structure and structure of the deposits, the symbiosis of minerals, the nature and degree of structural control, the composition of ore-bearing rocks, the relationship with igneous rocks, the characteristics and extent of alteration, and other factors Changes so large that it is difficult to more accurately define the type of deposit.Based on the above reasons, coupled with the fineness of gold and other associated minerals (mainly submicroscopic or microscopic) and difficult
