福建平和火山盆地位于华夏板块的东南缘,闽东火山活动亚带西南部,上杭—云霄构造岩浆成矿带的东段。其中上杭—云霄构造岩浆成矿带是福建省重要的多金属成矿带之一,主要活动期为燕山晚期,早白垩世发生了大规模的岩浆作用,形成了一系列火山盆地及相应的侵入岩浆系统,并形成了丰富的铜、金、银、钼等多金属矿床,例如紫金山、大排及平和—云霄矿集区。前人对紫金山矿集区成岩成矿与岩浆作用的关系等方面进行了大量的研究,认为其属于典型的斑岩型-浅成低温热液型成矿系统。平和地区与紫金山 Fujian Pinghe volcanic basin is located in the southeastern margin of the Huaxia plate, the southwestern part of the Mindong volcanic activity belt and the eastern segment of the Shanghang-sky tectonic magmatic mineralization belt. The Shanghang-Yunxiao structural magmatic metallogenic belt is one of the important polymetallic metallogenic belts in Fujian Province. The main activity period is the late Yanshanian and Early Cretaceous. Large-scale magmatism took place and a series of volcanic basins have been formed Intruded into the magmatic system, and formed a wealth of copper, gold, silver, molybdenum and other polymetallic deposits, such as the Purple Mountain, big row and Pinghe - Yunxiao mine area. The predecessors made a great deal of researches on the relationship between diagenesis and magmatism in the Zijinshan ore district, and considered that it belongs to the typical porphyry-epithermal mineralization system.
