兰坪县大村头铁矿区位于沘江与澜沧江断裂之间,矿区出露地层有:下第三系果朗组、云龙组;上白垩统虎头寺组、南新组,下白垩统景星组;上侏罗统坝注路组,中侏罗统花开左组等地层。断裂构造发育,断裂构造具容矿又控矿,矿(化)体基本赋存构造破碎带中,矿化标志主要为褐铁矿,构造规模与破碎带成矿成正比,与地层岩性关系不大,矿区内的破碎带是寻找铅锌矿、铜、铁、汞、金主要找矿空间。
The Dapudou Tiantie Mine in Lanping County is located between the Qijiang River and the Lancangjiang Fault. The outcrop formations in the mine area include the Lower Tertiary Langlang Formation and the Yunlong Formation, the Upper Cretaceous Huotousi Formation, the Nanxin Formation and the Lower Cretaceous Star Group; Upper Jurassic dam injection group, Middle Jurassic flowering left group and other formations. The fault structure is developed and the fault structure is of ore-bearing and ore-controlling. The basic ore-bearing body of the ore body is structurally fractured, and the mineralized sign is mainly limonite. The tectonic scale is proportional to the metallogenesis of the fractured zone and is related to the lithology of the formation Not big, the mining area is looking for the broken belt of lead-zinc, copper, iron, mercury, gold, the main prospecting space.
