摘要
葫芦丘铅锌矿产于矿区北东向构造蚀变脉中,矿体呈透镜状、脉状,明显受断裂构造控制。矿区出露地层单一,为侏罗系上统南园组第二段,岩性为中酸-酸性火山碎屑岩。成矿与岩浆侵入及火山活动紧密相关,为中低温岩浆-火山热液型矿床。
The lead-zinc mine of Calabash Mound is produced in NE-trending structural alteration veins,and the ore body is lentieular and vein like,which is obviously controlled by fault structure.The exposure strata in the mining area is single,and it is the second section of Jurassic system of South Park group,whose lithology is medium-acid to acid clastic rocks.The mineralization is closely related to magatic intrusion and volcanic activity,which is middle-low-temperature maga--volcanic hydrothermal type deposit.
