| 摘 要： | 凡口大型层控铅锌矿床位于广东省北部,中上泥盆纪湘、桂、粤海盆的东部边缘。产于加里东运动后中上泥盆系近底部的碳酸盐岩中。有关它的成因曾提出过礁控成矿、成岩改造及火山成矿等见解。笔者两年来做了较多研究工作,本文将对地质特征和矿床成因于以讨论。

| Abstract: | The huge lead and zinc deposit of Fankou, Guangdong is a strata-bound ore deposit located in carbonate rocks of Middle -Upper Devonian series. The orebody chiefly appears in the transition zone between the carbonate rock and the fragme-ntal rock, and also in the carbonate rock. The orebody is controlled by faults.The ore-bearing rocks mostly are micrites with a great deal of algaes and contain a good few of terrigenous clastic and carbonaceous sediments. The dolomitization of the ore-bearing rocks is not intense. There are, however, residues of wall rocks in the orebody which is bordered by joints on the surrounding rock. |
