本文主要研究内容
作者耿树峰（2019）在《辽宁省凌源市柏杖子金矿床成矿地质特征与成矿预测》一文中研究指出：本文以辽西地区规模较大的辽宁省凌源市柏杖子金矿床为主要研究对象,通过对研究区内地质、地球物理、地球化学特征等综合研究,系统分析了区内地层、构造、岩浆岩等对柏杖子金矿床形成的制约条件,总结了成矿地质条件和找矿标志,在提取成矿预测要素的基础上,建立了矿床预测模型,圈定了远景预测区,这项研究不仅为该矿床下一步找矿勘查提供科学依据,而且能为相关地区找矿预测提供借鉴。矿床地质研究揭示,研究区出露的地层主要为新太古界八道河岩组和中元古界长城系大红峪组,岩浆岩主要燕山早期呈岩株、岩脉及株脉联合体的闪长岩类、花岗岩及中基性—酸性脉岩类,构造主要是北东—北北东向压扭性断裂破碎带;矿体主要产在北东—北北东向压扭性断裂破碎带内,围岩为中元古界长城系大红峪组和燕山期花岗岩。矿床工业类型为含金硫化物石英脉型与蚀变岩型两种兼顾的复合型矿床;其中,石英脉型矿体分布在大红峪组石英砂岩和柏杖子花岗岩岩体内,Au品位较高,矿体规模较小,矿体沿走向和倾向尖灭再现、分枝复合、局部具膨大收缩等特征明显;蚀变岩型矿体仅在花岗岩体内产出,Au品位较低但较稳定,矿体规模较大,局部具膨大收缩特征,矿体较连续。矿床形成经历了黄铁矿—石英阶段、多金属硫化物—银金矿—石英阶段、碳酸盐化三个阶段,成矿作用发生在多金属硫化物—银金矿—石英阶段。地球物理特征揭示研究区依据物性特征和激电异常的分布规律,可以有效地划分闪长岩和花岗岩、石英砂岩界线,电阻率异常准确地圈出二长斑岩等脉岩界线;金矿导致异常具有高极化率低电阻率的特点。地球化学特征揭示柏杖子金矿床地表次生晕最佳元素组合Au-Ag-Cu-Pb-Mo,在地表出现上述元素浓集中心和分带性明显的主体带状组合异常与隐伏矿体吻合,在剖面上Au表现为跳跃式多峰异常。成矿岩体、构造、地球化学、地球物理特征等为预测必要要素,沉积建造类型为预测重要要素,矿物组合、结构构造等为预测主要要素。综合以上研究,得出该类型矿床为中温热液型金矿床,成矿受地层、构造、岩浆岩联合控制。岩浆活动和围岩为成矿提供了热动力和物质条件;断裂裂隙构造为含金热流体运移提供了通道和矿质沉淀的场所,从区域成矿作用与预测角度出发,建立了该矿床成矿地质模式和预测模型,进而圈定出了柏杖子—苗家沟金多金属矿、厚杖子—八道沟金多金属矿、对面山—小河东铜钼金矿三个找矿预测区。
