一、前言文圣马(Vinsanmaa)研究区位于芬兰北部。奥托昆普公司曾于60年代在文圣马进行过勘查。在研究区北西约1公里处的钠长石辉绿岩中发现了一个含黄铜矿(含Cu约4%)的矿化石英岩脉。该矿脉平均含Au 3g/t。但矿化范围太小,不值得开采。在80年代初期芬兰地调所地球化学室所作的区域冰碛物化学图上,文圣马矿脉 I. Introduction The Vinsanmaa study area is located in northern Finland. Outokumpu undertook a survey in Manila in the 1960s. A mineralized quartzite vein containing chalcopyrite (about 4% Cu) was found in the albite diabase about 1 km northwest of the study area. The vein contains Au 3g / t on average. However, the mineralization is too small, not worth mining. On the chemical map of the regional moraines made by the Geochemistry Department of Finland in the early 1980s,
