| 摘 要： | 安林地区的构造活动,对剖析太行山东麓构造岩浆带成生、演化具有一定的代表性。本区自燕山运动开始就受到了变质核杂岩和伸展拆离构造控制,区内主要构造有NNE向和NW向两组,其中NNE向构造在区内等间距形成了五条规模大的深断裂,均具高角度正断层性质。NW向构造形成了天喜镇-磊口北西向构造岩浆岩带,包括了塔山穹窿式背斜和白玉村-宝山墙状岩体,两组构造均对燕山晚期中-碱性岩浆上侵和安林式矽卡岩型铁矿的形成具重要控制作用。

| Abstract: | The tectonic activity in Anlin region has certain representative for analysis the forming and evolu-tion of tectonic magma belt in east Taihang mountain.The region is controlled by metamorphic core complex and extensional detachment structure.There are two groups of structure of which trend are in NNE and NW respectively,and the NNE trending structure includes five big scale faults which distribute in equidistant with high angle normal faulting.The NW trending structure formed the Tianxi-Leikou magmatite belt of which include Tashan dome type anticline and Baiyucun-Baoshan dike type magmatite.The all two group structures have great important controlling function to the intrusion of mid-alkaline magma formed in late Yanshan period and Anlin type skarn iron ore. |
