| 摘 要： | 寿宁—福州一带蕴藏丰富的叶蜡石矿资源，多产于南园群火山碎屑岩地层中，小溪组地层为最主要赋矿层位，围绕火山机体发育的环状断裂为成矿最有利部位，近矿围岩普遍发育次生石英岩化，围岩蚀变具有明显的水平及垂直分带现象。

| Abstract: | The Shouning-Fuzhou area is rich in pyrophyllite, which exists mostly in the pyroclastic rock of the Upper Jurassic Nanyuan Formation strata.The Xiaoxi Formation strata (Upper Jurassic) is a main host layer.The ring fractures around the volcanic apparatus are the most favorable sites of metallotectonics.The secondary quatzitization is common in the country rock near the pyrophyllite and there occurs obvious horizontal and vertical zonation. |
