佛子冲铅锌成矿带包括两种矿床类型 ,即佛子冲式夕卡岩型矿床和牛卫式热液充填 (交代 )型矿床。这两类矿床矿体产状、围岩蚀变、矿物组合 ,以及单矿物中微量元素分布特征等方面区别明显 ,但硫化物矿物的硫、铅同位素组成相同 ,并且均表现出强烈的均一化的特点 ,反映出两者的成矿条件及成矿方式虽然不同 ,但具有相同的物源———燕山期钙碱性火山岩系。在佛子冲矿带南部火山岩覆盖区 ,铅锌矿化组合空间展布呈“三层楼”结构 ,并且构造控矿作用明显 :矿点主要分布于佛子冲隐伏背斜的轴部 (“龙脊”) ,特别是在隐伏背斜被NE向断裂切割部位。火山岩区铅锌矿化大多属于佛子冲式矿床类型 ,即佛子冲矿带内主要的矿床类型 ,具有较大的找矿前景。
The Fozichong Lead-Zinc metallogenic belt includes two types of deposits, namely, the Fozi-type skarn-type deposit and the Niuwei-type hydrothermal filling (metasomatic) deposit. The two types of deposits are different in ore body formation, wall rock alteration, mineral assemblage, and trace element distribution in single minerals. However, the sulfur and lead isotopic composition of sulfide minerals are the same and both show strong homogeneity , Which reflects that although the metallogenic conditions and metallogenic methods of the two are different, they have the same provenance --- the Yanshanian calc-alkaline volcanic rock series. In the volcanic rock cover area of the southern part of Fozongpo ore belt, the lead-zinc mineralization assemblage is distributed in a “three-storey” structure with obvious ore-controlling action: the ore spots are mainly distributed in the axis of the Fozhu anticline (“ Dragon ridges ”), especially in the hidden anticlines NE NE fracture fracture site. Most of the lead-zinc mineralization in the volcanic area belongs to the Fozi Chong deposit type, which is the main deposit type in the Foziong ore deposit and has a great potential for prospecting.
