摘要
东川铁架山含铁层位是大营盘组, 其上、下盘层序及其与青龙山组之间的满银沟运运界面十分清楚, 肯定此区的层序划分对四川老油房向斜层序及满银沟的含铁层位归属有指导作用。禄劝金沙江两岸的昆阳群、会理群连成一片, 但此区的层序划分有四种方案, 查明并确立此区的层序, 对四川铜厂鼎、红旗沟铜矿。
The Fe bearing horizon of Tiejia mountain belongs to the Dayingpan Formation. Its stratigraphic sequence to the upper or lower strata and the boundary surface of Manyingou Movement between it and Qinglong Mountain Formation are very clear. To set up the stratigraphic sequence of this area has a direction significance for the determination of the stratigraphic sequence of Laoyoufang syncline in Sichuan and the Fe bearing horizon of Manyingou. The Kunyang Group and Huili Group of both sides of Jinsha River in Luquan are linked up each other. However, there are 4 viewpoints in the division of stratigraphic sequence of this area. To set up the stratigraphic sequence in this area has a direction significance for the determination of the horizon of all ore bearing beds of Tongchangding, Hongqigou Cu deposits, Xianglu Mountain Fe deposits and Maan Mountain Pyrite deposits.
