吉黑东部斑岩型-浅成热液型铜金矿床多重成矿模型

通过四个典型矿床（小西南岔、闹枝、五凤和刺猬沟）的对比，发现它们在形成时间-空间一成因上既相互联系，又相互区别。小西南岔和闹枝矿床存在三个成矿流体系统：加热天水系统(A)、排放流体系统(B)、蒸气缕(steam plume)反应系统(C)；五凤和刺猬沟矿床只有一个成矿流体系统，即排放流体系统(B)。前者的成矿流体由浅成岩浆房的补给；后者的成矿流体主要为循环天水，浅成岩浆房的补给不明显。小西南岔金铜矿床产于中生代火山岩盆地边缘的隆起带，属于斑岩型矿床；闹枝金（铜）矿床产于中生代火山岩盆地内的断隆块，属于斑岩-浅成热液过渡型矿床；五凤和刺猬沟金（银）矿床产于中生代火山岩盆地内断裂带，属于浅成热液型矿床。在区域成矿上，由浅入深，浅成热液型斑岩-浅成热液过渡型和斑岩型构成多重成矿模型。

The multiple metallogenic model of the porphyry-epithermal copper-gold deposits in eastern Jilin and Heilongjiang

Based on comparative study of four typical deposits, i.e. Xiaoxinancha, Naozhi, Wufeng and Ciweigou, it is found that they are both related to and distinguished from each other in time, space and genesis. The Xiaoxinancha and the Naozhi deposit have three ore fluid systems, namely heated meteoric water system (A) , discharge fluid system (B) and steam plume reaction system (C), whereas the Wufeng and the Ciweigou deposit have merely one ore fluid system, i.e. discharge fluid system (B). Ore fluids in the former deposits are provided by shallow-seated magma chamber, whereas ore fluids in the latter deposits are mainly circulating water, with no distinct supply from the magma chamber. The Xiaoxinancha copper-gold deposit occurs in the upwarped zone rimming the Mesozoic volcanic basin, being of porphyry type; the Naozhi gold (copper) deposit occurs in the lifted block within the Mesozoic volcanic basin, belonging to porphyry epithermal transitional type; the Wufeng and the Ciweigou gold (silver) deposit, which are two epithermal deposits, exist in the fault zone within the Mesozoic volcanic basin. From the surface to the depth in regional ore-forming activities, the epithermal type, porphyry-epithermal transitional type and porphyry type constitute a multiple metallogenic model.
