中文摘要：
位于西秦岭岷（县）-礼（县）成矿带西段的马坞金矿床，是近年发现的一个中型微细浸染型金矿床。系统地研究了该矿床8号矿体黄铁矿的热电性标型特征，结果表明：8号矿体的黄铁矿热电导型以N型为主，总含量达到71.2％；成矿温度主要集中于200～300℃，属于中温矿床；黄铁矿热电导型及热电性参数特征反映出矿体被剥蚀到中部偏下的位置，向深部仍有一定规模的延伸；P型黄铁矿出现的频率从浅部到深部呈减小、增大再减小的趋势；金品位的高值区域、P型黄铁矿热电系数平均值的高值区域与热电系数离散度的高值区域三者相互对应。
英文摘要：
Located in the western part of the Min-Li metallogenic belt in the Western Qinling Mountains,the Mawu gold deposit is a medium carlin-type disseminated gold deposit discovered in recent years.Based on a study of the thermoelectric characteristics of pyrites in No.8 orebody,the authors put forward the following con-clusions.The thermoelectric properties of pyrites in No.8 orebody are mainly of the N type,with a total content of 7 1.2%.The ore-forming temperature of the deposit ranges from 200 to 300 ℃,indicating that the deposit is a medium temperature gold deposit.The thermoelectricity characteristics imply that the lower to middle parts of the orebody have been eroded,and there exists an extension of No.8 orebody in the deep.The frequency of P-type pyrite is reducing,and then increasing and finally decreasing from top to bottom.The high average gold grade corresponds with the high P-type pyrite thermoelectric coefficient value and the high thermoelectric coeffi-cient dispersion value.
