| 摘 要： | 矿山村铁矿是邯邢地区的一个中型矽卡岩型铁矿。通过对该铁矿矿物的流体包裹体均一温度、盐度和流体包裹托气液相成分等诸多方面的初步研究表明,其成矿流体属中高温(110℃～530℃)、中高盐度(18.0%～21.0%)、K+-Na+-Ca2+-Mg2+-Cl--SO42--F-体系;气相成分以H2O为主,次为CO2、CH4、H2,成矿流体可能主要来源于岩浆热液,部分来自大气降水。因此认为矿山村铁矿在成矿过程中由于与之关系密切的岩体多期次侵位活动,带入新的热源,由于部分大气降水的加入,导致铁质沉淀成矿。

| Abstract: | The Kuangshancun Fe deposit is one of medium-sized skam-type Fe deposits in the Hanxing area. Study of homogeneous temperature, salinity and gas-liquid ingredients of fluid inclusions shows that the ore fluids was characterized by to mid-high temperature （ 110-530℃ ） , mid-high salinity （ 18.0%-21.0% ） and K＋-Na＋-Ca2＋-Mg2＋-Cl-SO42-F system. The gas composition of the fluid inclusions is dominated by H20, and secondly CO2, CH4 and H2. The mineralization fluids might originate primarily from magmatic hydrothermal fluid, and partly from meteoric water. The ore-formation of the Kuangshancun iron deposit was related to multiple emplacement activities of intrusion. |
