在黑龙江省S地化探样品分析中,发现Cu、Zn、Mo的总量有异常特征,为鉴别矿致与非矿致异常,选择相态分析的方法对化探异常样品进行筛选和评价。Cu、Zn、Mo这三个元素的相态分析一般可分成氧化物相、硫化物相、结合相三个相态进行测定[1-8]。Cu、Zn矿床的主要工业矿物均为硫化物矿物,Cu、Zn的化探异常,当硫化物相(即工业矿物相)和氧化物相(即次生工业矿物相)为主时,在异常区很容易找到Cu、Zn的矿化。Mo的工业矿物实际上只有辉
In the analysis of geochemical exploration samples in Heilongjiang Province, the total amount of Cu, Zn and Mo was found to have abnormal features. In order to identify the abnormalities caused by ore-induced and non-ore-derived events, the method of phase analysis was used to screen and evaluate the abnormal geochemical samples. Phase analysis of the three elements Cu, Zn and Mo can generally be divided into three phases: the oxide phase, the sulfide phase and the binding phase [1-8]. The main industrial minerals of the Cu and Zn deposits are all sulfide minerals, and the geochemical anomalies of Cu and Zn. When the sulfide phase (ie, the industrial mineral phase) and the oxide phase (ie, the secondary industrial mineral phase) are dominant, It is easy to find Cu, Zn mineralization in the area. Mo’s industrial minerals are actually only brilliant
