| 摘 要： | 莱州-安丘铁成矿带位于沂沭断裂带东侧,胶北隆起的西南部。成矿带呈NE向展布,长约100 km,宽10~20km。已知区内铁矿类型主要有沉积变质型、岩浆熔离型和岩浆期后热液型,成矿除受地层控制外,还与构造、岩浆活动关系密切。通过对地质和重、磁物理场的分析,确定不同成因类型铁矿的分布范围,并且划分出不同磁异常特征,指出今后的找矿方向。

| Abstract: | Laizhou-Anqiu iron metallogenic belt is locateed in the east part of Yishu fault,and southwest part of Jiaobei uplift.The metallogenic belt extended with the trend of NE.Its length is about 100km and the width is 10~20km.Major iron ore types known in this region mainly include sedimentary metamorphic type,magma segregation type and post-magmatic hydrothermal type.In addition to the stratigraphic contro,mineralization also has close relation with tectonic and magmatic activities.Through analysis on geology,gravity and magnetic field,distribution of different types of iron ore are determined,and different characteristics of magnetic anomalies are classified.It will point out the direction for ore prospecting in the future. |
