新疆西准噶尔提依尔金矿黄铁矿热电性与微量元素特征及其地质意义
|
摘要
黄铁矿是提依尔金矿主要的载金矿物,其标型特征的研究对深部找矿具有重要的指示意义。从矿物学和矿物地球化学角度系统研究黄铁矿热电性和微量元素组合特征,结果表明,黄铁矿导电类型以P-N混合型为主,P型黄铁矿出现率从浅部到深部有逐渐升高的趋势,结合各钻孔金品位垂向变化,可知P型黄铁矿出现率与金品位高值区呈正相关关系,且与矿体侧伏方向一致,预示矿体向深部有一定的延伸;成矿温度主要集中在100~330℃之间,属于中低温热液矿床;黄铁矿微量元素(As+Sb+Se+Te、Cu+Pb+Zn和Ti+Ni+Co+Cr)纵投影等值线图显示,250 m标高以下,0、1号勘探线之间往NW方向找矿潜力良好。获得的黄铁矿标型特征对于提依尔金矿床深部找矿具有重要指导意义。
Pyrite is the main gold-bearing mineral in Tiyier gold deposit,the typomorphic characteristics of which is of great significance to deep prospecting. In this paper,the thermoelectricity and trace element characteristics of pyrite were systematically studied from the perspective of mineralogy and mineral geochemistry. The results show that the conductivity type of pyrite is mainly P-N hybrid type,and the occurrence rate of P-type pyrite gradually increases from the shallow to the deep part. Combining the vertical change of gold grade of differ-ent drilling,it is well known that the occurrence rate of P-type pyrite is positively correlated with the high gold grade. Moreover,the occurrence rate of P-type pyrite is consistent with the direction of lateral volts of orebody,which indicates that the ore body has some extension to the deep part. The ore-forming temperatures range from100 to 330 ℃,which belong to epithermal deposit. The vertical projection contours of trace elements( As + Sb+ Se + Te,Cu + Pb + Zn and Ti + Ni + Co + Cr) from pyrite show that the great prospecting potential existed under-250 m elevation between exploration line 1 and line 2 to northwest. Given the above,the typomorphic characteristics of the pyrite are significant for deep gold prospecting in the Tiyier gold deposit.
