吉林延边地区为我国滨太平洋带的一个重要的金属成矿区。与中生代火山-次火山侵入活动有关的斑岩型。浅成热液型矿床在时空上、成因上构成一个成矿系列。本文选择四个代表性矿床(小西南岔、闹枝、五凤和刺猬沟),较详细地介绍它们的成矿地质背景、矿床地质特征、流体包裹体、稳定同位素及成矿机制等。通过这些矿床的描述,勾画出一幅从中生代火山盆地边缘的隆起带的斑岩型矿床(小西南岔)→中生代火山盆地内部的断隆块的斑岩-浅成热液过渡型矿床(闹枝)→中生代火山盆地内部断裂带的浅成热液型矿床(五凤和刺猬沟)的全景。
The Yanbian area in Jilin is an important metallogenic area in China’s Pacific Rim. Porphyry associated with Mesozoic volcano-subvolcanic activity. The epithermal deposits constitute a metallogenic series on the basis of time and space. In this paper, four representative mineral deposits (Xiaoxi-Nancha, Jazhi, Wufeng and hedgehog) are selected to describe their metallogenic geological background, geological features, fluid inclusions, stable isotopes and metallogenic mechanisms in more detail. Through the description of these deposits, a porphyry-epithermal transitional deposit of the uplifted blocks in the interior of the Mesozoic volcanic basin from the porphyry deposit (Xiaoxinancha) in the uplifted belt on the margin of the Mesozoic volcanic basin Branches) → panorama of epithermal deposits (Wufeng and hedgehog) in the interior fault zone of the Mesozoic volcanic basin.
