北塔山地区石英脉红外光密度特征及其意义

新疆北塔山东南部及小哈甫提克地区石英脉中Ｈ２Ｏ的相对光密度绝大部分大于１．０大部分在３～５之产变化，ＣＯ２的相对光密度大于０．１，大部分在０．３～０．５之间的变化，随着石英脉中Ｈ２Ｏ的相对光密度平均值由于２．５０→３．９５→４．８７，Ｈ２Ｏ与ＣＯ２的相对光密度比值的平均值由６．４３→７．２０→１３．３４，金的平均含量由零逐渐升高，含金石英脉由近地表深部，Ｈ２Ｏ和ＣＯ２相对光密度平均值分别为４．９５

CHARACTERISTICS AND SIGNIFICANCE OF INFRARED SPECTROMETRIC PHOTODENSITY OF QUARTZ VEINS,BEITASHAN,XINJIANG

In the southeast of Beitashan and Xiao Haputik area,Xinjiang,the relative photodensity of water D (H 2O) is higer than 1 0,varing mainly from 3 0 to 5 0,while the value of carbon dioxide D (CO 2) is higer than 0 1,varing from 0 3 to 0.5.With the average value of D (H 2O) varing from 2 50 to 3 95 to 4 87,and the average value of D (CO 2) varing from 6 43 to 7 20 to 13 34,the average contents of Au gradually increase from 0.While the relative photodensity value of water and carbon dioxide near the surface are higher than that in deeper parts,i.e the average value of D (H 2O) and D (CO 2) is from 4 95 to 4 46,from 0 58 to 0 41,respectively.The average contents of Au are more and more higher in deeper parts.In the east of the Baitashan anticline,the plunging part,the quartz veins are rich in water,poor in carbon dioxide and mostly gold bearing.On the contrary,in the west of the Baitashan anticline,the upwarping part,the quartz veins are rich in carbon dioxide,poor in water,and hardly gold bearing.The quartz veins in the studied region are hypergene and crystallized in the condition rich in water.
