山东招掖金矿带内花岗岩与金矿化关系探讨

以花岗岩类及脉岩类的精确定年结果为基础，结合区内金矿床地质特征和近年来研究新进展，探讨了花岗岩类侵入与金矿化之间的空间、时间和成因关系。尽管区内花岗石类侵入体与金矿床间存在密切的窨及时间关系。但它们之间并不存在直接的成因联系，即这些金矿床并不是岩浆热液矿床。花岗石类侵入体和脉岩类的侵位通道和先存韧性剪切带是贯通深部流体的导矿构造，有利于深部成矿流体和上升和流体循环；花岗岩类与围岩的接触带及其内部断

DISCUSSION ON THE RELATIONSHIP BETWEEN GRANITOID AND GOLD MINERALIZATION IN THE ZHAOYE GOLD BELT, SHANDONG PROVINCE

Based on the reliable chronological data of granitoid and dikes, geological features of the gold deposits and progresses in gold deposit study, the spatial, temporal and genetic relationships between granitoid intrusives and gold mineralization have been discussed. Although granitoid intrusives in the belt are spatially and temporally associated with gold mineralization, there is no direct genetic link between them, namely, these gold deposits are not magmatic hydrothermal deposits. The emplacement paths of the granitoid intrusives and dikes and the pre exist ductile shear zones were the structures as passageway for deep seated ore fluid, which were favorable to the elevation and circulation of the mineralizing fluid. The contacts of granites with host rocks and the fractures within the granites were favorable sites for gold precipitated.
