| 中文摘要: |
| 黑龙江省小兴安岭地区多金属矿产资源丰富,多与区域火山—岩浆活动密切相关,火山机构的精准、快速定位对区域矿产勘查具有重要意义,而小兴安岭地区基岩出露条件较差,文章尝试性地将航空磁力测量资料和数字高程模型(Srtm_DEM)数据相结合,在研究区内八家子地区解译出一火山机构及多组断裂构造,该成果丰富了该区地质信息；在覆盖区利用航磁和Srtm_DEM数据进行火山机构和断裂构造解译具有独特的优越性,能为区域寻找与次火山岩相关多金属矿产提供参考。 |
| 英文摘要: |
| In Xiaoxinganling Mountain region of Heilongjiang,there are lot of polymetallic mineral resources, most of the deposit are related to the regional volcanic-magmatic activities. Hence, the accurate and rapid positioning of volcanic edifice provides an important clue to conduct mineral exploration in this area. However, the outcrop of bedrocks in Xiaoxinganling Mountains region is very poor.This paper attempts to combine aeromagnetic and Srtm_DEM datas and has interpreted out the volcanic edifice and several groups of fracture structures in Bajiazi area, the resultshave enriched the geological information in this area. In the primeval forest covered area, the aeromagnetic and Srtm_DEM dates have unique advantage in the structural interpretation works and can provide information for mineral exploration of metal minerals related to the subvolcanic rocks. |
