辽宁王营子钼矿地质特征及找矿标志
|
摘要
辽宁省朝阳市王营子钨钼矿位于努鲁儿虎山脉大青山东部,属辽西凌源—北票金成矿带高杖子—大庙—东五家子金成矿区中部,蝴蝶沟—王营子金钼多金属矿化带。研究区内地层、岩浆岩发育较好,构造未见明显特征。主要岩体以斑状花岗岩、似斑状花岗岩为主,矿体严格受似斑状花岗岩控制,富集于钾化似斑花岗岩中,矿脉与围岩无明显界线。基于野外实际勘查、成矿地质条件等的研究,认为王营子钼矿为细脉浸染型斑岩型钼矿,并总结了找矿标志。
The Wangyingzi tungsten and molybdenum deposit in Chaoyang City, Liaoning Province is located in the eastern part of the Dalu Mountain in the Nulu Erhu Mountains. It belongs to the middle part of the Jincheng mining area in the Gaoyuanzi-Diaomiao-East Wujiazi gold ore belt of the Lingyuan-Beipiao gold metallogenic belt in Liaoxi, and the butterfly ditch is king. Camp gold molybdenum polymetallic mineralization zone. The stratum and magmatic rocks in the study area have developed well and no obvious features have been found in the structure. The main rock masses are mainly porphyric granites and porphyritic granites. The ore body is strictly controlled by speckle-like granites and enriched in potassic speckle granites. There is no obvious boundary between the veins and surrounding rocks. Based on field investigations and geological conditions of mineralization, the Wangyingzi molybdenum deposit is considered to be a fine-vein infective porphyry molybdenum deposit, and the prospecting mark is summarized.
