苍山县龙宝山金矿床地质特征

Geological Characteristics of Longbaoshan Gold Deposit in Cangshan County

摘要:

苍山县龙宝山金矿床位于龙宝山中偏碱性杂岩体的内部 ,赋存于NNE向及SN向次级断裂内。矿体呈脉状 ,沿走向、倾向具膨胀、收缩、分支、复合现象 ,矿化较连续。该区中生代燕山早期岩浆活动强烈 ,剧烈的构造运动为金元素的活化、迁移、富集、沉淀提供了通道和成矿空间。矿床成因为中低温热液蚀变石英脉型

Abstract:

Longbaoshan gold deposit locates in Longbaoshan medium to alkalic complex in Cangshan county, which occurred in subfractures with the trend of NNE and SN. Orebodies show as vein, and have phenomenons as dilatation, striction, offset and recombination along the direction of strike and tilt with a continuous mineralization. Magmatic movements were strong in early Yanshan period of Mesozoic. Strong movements provided ore-forming space for activization, transportation, concentration and settlement of gold element. It belongs to medium-low temperature altered quartz vein type.
