中国东南大陆自古元古代以来历经多期次构造岩浆活动,形成了多个具不同特色的构造成矿单元,其中闽西南地区位于永安—梅州晚古生代坳陷盆地的主体部位,盆地中充填的厚度不等的晚古生代碎屑岩—碳酸盐岩建造及中生代火山-侵入活动为同生或后期铁铜多金属成矿作用创造了良好的成矿物质及热液来源,形成一批以紫金山铜金矿床、马坑铁矿等为代表的大(中小)型矿床或矿化点。闽西南地区成矿地质条件及成矿规律研究对地该区进一步找矿具有重要的理论与实际意义。
Since the ancient Paleozoic, the southeastern part of China has experienced multiple stages of tectonomagnetism and formed several structural mineralization units with different characteristics. Among them, the southwestern Fujian Province is located in the main part of the Late Paleozoic depression basin in the Yongan-Meizhou Basin. The thickness of the filling in the basin Unequal Late Paleozoic clastic rock-carbonate rock formation and Mesozoic volcanic-intrusive activities have created a good source of ore-forming materials and hydrothermal fluids for the same or later iron-copper polymetallic mineralization. Copper and gold deposits, Ma Hang Iron Mine, represented by the large (small) deposits or mineralization point. Study on Metallogenic Geological Conditions and Metallogenic Law in Southwestern Fujian Province It is of great theoretical and practical significance to further prospecting gold in this area.
