Abstract:Cangbo area in Shandong province is rich in iron ore resources. It is a typical "Anshan type" iron oreforming area. Several large and medium iron deposits have been discovered and evaluated successively. On the basis of introducing the metallogenic geological characteristics of Cangfu iron ore belt, it can be divided into five orebearing belts. The ore bodies occur in the middle and upper part of Shancaoyu formation of Taishan group, which are strictly controlled by strata of Shancaoyu formation. The distribution pattern is controlled by two fold structures of Taibai syncline and Shiyan anticline. The fault structure destroys the continuity of orehosting structure and ore body, and indirectly controls the occurrence and distribution of iron ore bodies. The protolith formation is basic volcanic rockintermediate acid volcanic rocksiltstoneferrosiliceous formation, which belongs to volcanic intermittent mineralization. It is concluded that the source of oreforming materials is closely related to submarine volcanic activities. After the late metamorphism, the oreforming materials are enriched. The deposit is a sedimentary metamorphic iron ore deposit produced in an iron ore deposit with biotite granulite as the main rock layer and amphibolite as the main rock layer. After the iron deposit, it is superimposed by strong tectonichydrothermal transformation in the later period, and the ore body is mainly layered and lenticular. Syncline structure is the best structural model for ore body enrichment and preservation. The thickness of ore body near the core of syncline increases, and the grade also tends to increase.
