三山岛金矿构造特征及找矿意义

Tectonic characteristics and prospecting significance of sanshandaoGold mine

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 metallogenie 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.
