| 中文摘要: |
| 研究区位于华北地台北缘上黄旗构造岩浆隆起带上,矿产丰富。该区TM遥感图像上线性构造较发育,环形构造不太发育,蚀变色异常较少。已知矿床(点)常产出在北西向线性构造旁侧；北北东向与北西向线性构造的交汇部位多有矿床(点)出现；部分矿床(点)产出在环形构造边缘及其附近；大草坪矿床就位于基底隆起构造近中心部位；大草坪矿区有岩浆活动热点形成的蚀变色异常。燕辽成矿带钼(铜)矿床可分为辽西和冀北两段,辽西地区以钼多金属矿床为主,冀北地区以铜(钼)矿床为主；侵入岩与围岩条件对矿床的形成存在一定的制约性；矿床类型与成矿环境有关。研究结果显示该地区具有巨大的钼多金属矿找矿潜力。 |
| 英文摘要: |
| Located in the northern magin of North China Platform structural magmatic uplift belt, there are rich mineral resources in the study area. In the TM remote sensing image, linear structures are development, ring structures are not too development, alteration abnormal are less. The known deposits (point) often distributes in the side of NW trending linear structures. In the intersection part of NNE and NW-trending linear structures, more mine deposits have occurrences. Part of deposits occurs in the edge and its vicinity of ring structures. The dacaoping deposit is located in the center of basement uplift, and have alteration information anomaly formed by magma activity. The molybdenum(cu) deposit of Yanliao metallogenic belt can be divided into western Liaoning section and northern Hebei section, western Liaoning section is dominated by molybdenum polymetallic deposit, and northern Hebei section is dominated by cu(molybdenum) deposit. The conditions of intrusive rock and surrounding rock have certain conditionality on ore-forming. The deposit types are related to metallogenic environment. The study results show that this area have great prospecting potential of molybdenum polymetallic. |
