| Abstract: | The Dalaihe iron deposit, located in Qingyuan County, Liaoning Province, belongs to Anshan type of sedimentary-metamorphic reconstruction. The orebody is buried from 0 to 170 m deep, extending 410 m long. Surface trenching reveals the largest width of 20 m. The orebody, generally in lenticular shape, is inclined to northwest, with little horse. The direct wallrocks of orebody are amphibolite and magnetite amphibolite. The indirect surrounding rock is biotite plagiogneiss. The ore type is simply magnetite quartzite. The grade of ore is even. Preliminarily estimated resources are more than 3 000 000 t. |
