| 中文摘要: |
| 早子沟金矿是近年来西秦岭成矿带勘查的特大型金矿,2016-2017年在矿区详查的基础上,对北东向矿带的74-106勘查线地段进行了勘探。选择北东向矿带具代表性的Au1、Au9主矿体,详细对比分析了详查和勘探两阶段矿体产状、形态、规模、品位及金属量的变化情况。经勘探阶段大量加密工程的控制和对主矿体基本合理的连接,表明Au1主矿体倾角变陡、厚度变薄、延深加大、形态变规则、品位有高低变化、单矿体金属量减幅6.26%。 |
| 英文摘要: |
| Zaozigou gold deposit is a super-large gold deposit explored in the West Qinling metallogenic belt in recent years. Based on the general exploration of the mining area in 2016-2017, the 74-106 exploration line section of the NE-oriented ore belt was explored. The representative Au1 and Au9 main ore bodies in the NE-oriented ore belt were selected, and the changes in the occurrence, shape, scale, grade and metal amount of the ore body in the general exploration and exploration were analyzed in detail. Controlled by a large number of drilling engineering during the exploration phase and the reasonable connection to the main ore body indicate that the Au1 main ore body has a steep dip angle, a thinner thickness, an increased depth, a regular shape change, a high and low grade change, and a single ore body metal amount decrease was 6.26%. |
