| 摘 要： | 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－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（ｓｔｅａｍｐｌｕｍｅ）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，属于浅成熟液型矿床。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。

| Abstract: | Based on comparative study of four typical deposits, i. e. Xiaoxinancha , Naozhi , Wufengand Ciweigou , it is found that they are both related to and distinguished from each other intime, space and genesis. The Xiaoxinancha and the Naozhi deposit have three ore fluid sys-tems, namely heated meteoric water system (A) ,discharge fluid system (B) and steam plumereaction system (C) , whereas the Wufeng and the Ciweigou deposit have merely one ore fluidsystem , i. e. discharge fluid system (B). Ore fluids in the former deposits are provided by shal-low-seated magma chamber , whereas ore fluids in the latter deposits are mainly circulating wa-ter, with no distinct supply from the magma chamber. The Xiaoxinancha copper-gold depositoccurs in the upwarped zone rimming the Mesozoic volcanic basin , being of porphyry type;theNaozhi gold (copper) deposit occurs in the lifted block within the Mesozoic volcanic basin, be-longing 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 volcanicbasin. From the surface to the depth in regional ore-forming activities, the epithermal type,porphyry-epithermal transitional type and porphyry type constitute a multiple metallogenicmodel. |
