摘要
姑婆山钨锡矿田自岩体接触带往内依次分布夕卡岩型、夕卡岩-构造蚀变带复合型钨锡矿及构造蚀变带型锡矿,控矿构造研究表明,锡(钨)矿化及矿体主要受近EW、NE、NW向断裂及断裂与接触带构造复合控制,构造控矿型式多样,并决定矿(化)体的空间定位方式。硫、氢、氧、铅同位素等资料反映出成矿流体和成矿元素来源于燕山早期侵位的姑婆山岩体,不同矿床类型在成因上与岩体密切相关,属于与花岗岩体侵入有关的岩浆热液型矿床,只是风化、剥蚀条件不同,形成了不同的矿床类型。
From contacting zone to inner part of intrusive in the Guposhan W - Sn ore field, these exist in turn skarn - type, compound type of skarn and structure - alteration zone W - Sn deposits, and structure - alteration zone type Sn deposits. Studies on ore - controlling structures show that tin （tungsten） mineralization and ore bodies are mainly controlled by EW - , NE - and NW - trending faults or by compound of faults and contact zone structures. Ore - controlling structures are variable and affect location of ores and mineralization in space. Data of sulfur, lead, hydrogen and oxygen isotopes shows that ore - forming fluids and materials came from early Yanshanian Guposhan pluton. Geneses of different type deposits are related with the pluton, and the deposits belong to magmatie hydrothermal type related with granitic intrusives. Formation of different type deposits just dues to differences of weathering and erosion.
