摘要
小高家地区位于金岭铁矿区北部,出露地层主要为月门沟群、石盒子群、白青山群等,区内断裂和褶皱构造发育,断裂以北北东向断层为主,褶皱主要为金岭短轴背斜,区内金岭岩体大面积出露,为一中基性多阶段形成的杂岩体,在其与灰岩接触带上赋存铁矿体,区内圈定1个铁矿体,其成因类型为与中-基性侵入岩有关的接触交代型铁矿床。
Xiaogaojia area is located in the northern part of Jinling iron ore area.The exposed strata are mainly Yuemenggou group,Shihezi group and Baiqingshan group.Faults and fold structures are developed in the area.The faults are mainly north-east trending faults,and the folds are mainly Jinling short axis anticline.The Jinling rock mass in the area is a middle basic multi-stage complex formed in a large area.Iron orebodies occur in the contact zone between Jinling rock mass and limestone,and an iron orebody is delineated in the area.The genetic type is a contact metasomatic iron deposit related to intermediate-basic intrusive rocks.
