摘要
朱诺矿集区是重要的铜多金属矿集区,勘查关注找斑岩型铜矿床,兼顾评价钼银,前人尚未关注钨。本次工作首次在矿集区致古弄研究区新发现脉型白钨矿体1个,规模较小,初步控制长约200 m、厚约2 m,赋矿岩石为英安质晶屑凝灰岩和花岗闪长斑岩。白钨矿矿体主要由石英和白钨矿等矿物组成。基本分析结果显示,其中1件钨矿化英安质晶屑凝灰岩样品WO3含量为0.14%,其余14件样品结果在0.002%~0.003%。初步分析认为,白钨矿的发现可能指示深部存在隐伏含矿斑岩体,为后续勘查部署具有重要指导作用。因此,建议后续在该地区的勘查、开发应重视钨等元素的综合评价。
The Zhunuo ore district is an important copper polymetallic deposit area.The exploration focuses on finding porphyry copper deposits,evaluating molybdenum and silver,unattention has been paid to tungsten.In this work,for the first time,a new vein scheelite body was discovered in the Zhigunong study area in the Zhunuo ore concentration area.It is small in scale,with a preliminary control length of about 200 m and a thickness of about 2 m.The ore-bearing rocks are dacite crystalline tuff and granodiorite porphyry.Scheelite ore bodies are mainly composed of quartz and scheelite.The basic analysis results show that the WO3 content of one tungsten mineralized dactylitic tuff sample is 0.14%,and that of the other 14 samples is 0.002%~0.003%.The preliminary analysis shows that the discovery of scheelite may indicate the existence of hidden ore-bearing porphyry in the deep,which plays an important guiding role for the follow-up exploration and deployment.Therefore,it is suggested that the comprehensive evaluation of tungsten and other elements should be emphasized in the follow-up exploration and development in this area.
