| 摘 要： | 菜园子磁铁矿位于扬子地台西缘康滇地轴中段东缘,江舟—米市断陷盆地带南段,川滇黔相邻成矿区之会理—会东前寒武纪铁铜铅锌银成矿远景区内。通过对该矿床地质特征、物探异常特征与见矿效果的验证、矿体地质特征、围岩蚀变的分析,认为菜园子磁铁矿床为与晋宁期中基性次火山作用有关的"火山喷溢(发)—变质热液型"(赤)磁铁矿床。

| Abstract: | The Caiyuanzi magnetite deposit in Huidong, Sichuan lies in the Huili-Huidong Precambrian Fe-Cu-Pb-Zn Metallogenetic zone on the eatem margin of the Kangdian Axis. This paper deals with geological features and geophysical characteristics as well as wall rock alteration which indicate volcanic-metamorphic hydrothermal origin related to the Jinning intermediate-basic subvolcanism. |
