【摘要】 黄铁矿和石英是主要的载金矿物。黄铁矿形态标型、成分标型、热电性标型和石英红外光谱标型特征具有指导找矿意义。江西茅排金矿区270 m中段47勘探线及37~33勘探线的矿物标型特征为:黄铁矿形态见有八面体和五角十二面体,五角十二面体和八面体等聚形;出现空穴心型导电和混合型导电黄铁矿,若为电子心型导电黄铁矿,其热电动势和热电系数的绝对值相对较大;黄铁矿成分中检测出Cu;石英相对吸光度(37~33勘探线)DH2O0.940 3,DCO20.196 1,DCO2/DH2O0.259 1,略低于矿区研究样品的平均值(DH2O1.326 7,DCO20.309 0,DCO2/DH2O0.338 2)。表明该处应位于矿体的中上部,矿体向下有一定的延伸。更多还原

【Abstract】 Pyrite and quartz are mainly gold-bearing minerals in Maopai gold deposit of Jiangxi.The typomorphic characteristics of pyrite,in form,content,thermoelectricity and infrared spectrum of quartz,are instructively significant for prospect.Located in the prospecting lines Nos.47 and 37-33 on the middle 270 m section,the mineral typomorphic characteristics are as follows: pyrite possesses the combination of octahedron with pyritohedron,pyritohedron with octahedron,etc.It appearsas hole-centre and mix center conduction,if being electron-centre conduction,the absolute magnitudes of thermoelectromotive force and thermoelectromotive coefficient of pyrite are bigger relatively;pyrite contains Cu;the relative absorbency in quartz(D_H2O 0.940 3,D_CO2 0.196 1,D_CO2/D_H2O 0.259 1 in prospecting lines 37-33)is smaller than average(D_H2O1.326 7,D_CO20.309 0,D_CO2/D_H2O 0.338 2)in the deposit.The fact indicates that the location should be at the mid-upper part of the ore body,and the ore body should stretch deep down at a certain extent.更多还原
