| 摘 要： | 广东凡口铅锌矿床的主要金属矿物黄铁矿、闪锌矿和方铝矿均可分为四个世代。各世代的主要金属矿物的标型特征差异很大。黄铁矿的Co/Ni比值,闪锌矿的颜色、晶胞参数及Fe、Mn、Cd含量,方铝矿的Mn、Ag、Sb、Bi含量均随其世代不同而有规律地变化。该矿床属沉积-成岩、地下热水改造型的层控铅锌矿床。

| Abstract: | In this lead-Zinc ore deposit, the main ore minerals of each generationhave typomorphic peculiarities. the typomorphic genetic peculiarties ofpyrite and sphalerite formed in sedimentary-diagentic period are identicalwith or similar to those autogenctic pyrite and sphalerite formed inmodern sediments. The Co/Ni ratio of pyrit, the color, unit cell parameter,Fe, Mn and Cd contents of sphalerite, and the contents of Mn, Ag,Sb and Bi of galena vary with different mineral generations in a regularpattern. These characteristics indicate that this lead-zinc deposit is astrata-bound deposit formed by sedimentation-diagenesis at the-low tem-perature and transformed by under ground thermal water. |
