三山岛金矿构造特征及找矿意义
|
摘要
三山岛金矿矿床以构造控矿为主,控矿构造为三山岛-仓上断裂,断裂带内主断层为F1,由断层泥、糜棱岩及构造角砾岩组成,是成矿期的主要控矿构造,F1断层泥对深部上升的成矿热液起到阻隔富集作用。断裂带内有利成矿部位是断裂分支-复合部位、构造拐弯的引张部位,通过以大探测深度为特征的物、化探方法,查清主构造的变化情况,预测出下一步找矿方向。
SanshandaoGold mine deposits by structure ore-controlling primarily,ore-contr olling structure for three mountain island-the fracture,fault zone storehouse NaZhu fault as F1,by fault mud,different metamorphose degree and tectonic breccia component is metallogenic epoch of the main ore-control structures,F1,fault of deep mud rising hydrothermal ore-forming play barrier function of enrichment.Fault zone mineralization is advantageous in fracture branch-compound parts,structure the turning parts,led by zhang detecting depth is the characteristic of great things,geochemical methods,found out the main structural changes to predict next prospecting direction.
