摘要: 程潮铁矿为鄂东南地区典型的矽卡岩型矿床,控矿构造表现为接触热动力变质构造、接触面构造和各种断裂、裂隙的叠加复合控矿。矿体主要赋存于花岗岩与围岩接触面由陡变缓的部位,产在向岩体一侧凹进的近南北向向形凹槽中。根据岩体与围岩接触面向深部延伸推测:E14勘探线~0勘探线之间近南北向“脊”线两侧,以及W27勘探线以西,尤其是W49~W59勘探线部位,具备有利于成矿的地层和构造条件,找矿前景良好。

Abstract: Chengchao iron mine is a typical skarn deposit in the southeast of Hubei province.Ore-controlling structures are mainly characterized by the superposition of dynamic thermal contact metamorphic structure,contact zone structure and various faults and fissures.The orebodies mainly occur in the steep-to-gentle transition section of the contact plane between granite and wall rock, and lie in the synclinal trough of the near N-S strike to the side of magma rock.From the deep extension of the contact plane between granite and wall rock, we conclude that both sides along the “ridge” of the near N-S strike between E14 to E0 prospecting lines and the section west of W27 prospecting line, especially the section between W49 to W59 prospecting lines, are provided with the structural and stratigraphic conditions favorable for mineralization, and have good exploration prospects.

Key words: Contact plane, Ore-controlling characteristic, Prospecting direction, Chengchao iron deposit
