| 中文摘要: |
| 密山市杨木岗地区处于敦密深大断裂南侧，华力西晚期—燕山晚期构造岩浆活动强烈，铀矿化异常线索较为丰富，铀成矿条件优越。铀矿化主要赋存于华力西晚期岩体及其与下寒武统金银库组的内外接触带，受断裂构造、层间破碎带、岩体内外接触带控制，伴生赤铁矿化、矽卡岩化、萤石化、黄铁矿化等热液蚀变。依据研究区内的地层、岩体、构造等成矿地质条件分析，结合航放铀高场、遥感铁染及羟基蚀变异常等成矿有利信息考虑，认为研究区内的热液型铀成矿潜力较大，提出了预测远景区4个。 |
| 英文摘要: |
| The Yangmugang area of Mishan County in Heilongjiang province is located in the south side of Dunmi deep fault. The late Variscan-late Yanshaniantectonic magmatic activity is strong, the uranium(niobium) mineralization anomalies clues relatively abundant,the uranium metallogenic conditions of Yangmugang area superior. The mineralization is mainly distributed at inner and outer contact zones of the late Variscian magmatite rock and the lower Cambrian Jinyinku formation and is controlled evidently by faults,interlayer crushing zone,inner and outer contact zones of intrusive bodies and is often accompanied with hematitization,Skarn,fluoritizatio,pyritization and other hydrothermal alteration. According to the analysis of metallogenic condition such as strata,magmatic rock,structure,airborne radiometrichigh field of uranium,remote sensing iron stain and hydroxyl alteration information it is potential for prospecting hydrothermal uranium deposit in the area and 4 targets are put forward. |
