摘要
豫西地区是我国重要的金银铅锌钼钨矿产基地,具有较大的找矿潜力。同时该地区受黄土高原影响,形成大面积黄土覆盖区。为了更好在豫西地区开展土壤地球化学测量工作,提高勘查地球化学效果,服务找矿勘查工作,选择在豫西受黄土影响显著的崤山南坡开展土壤地球化学测量粒度试验研究。通过对42件样品的7个粒级(-4^+10目、-10^+20目、-20^+40目、-40^+60目、-60^+80目、-80^+100目、<100目)样品分析,试验结果显示在豫黄土覆盖区开展土壤地球化学测量采样粒度选用-20^+100目较为合适,该粒级样品可以降低黄土中细粒物质对土壤样品的干扰,为豫西受黄土影响地区开展地球化学找矿工作提供了技术参考。
Western Henan Province is an important gold,silver,lead,zinc,molybdenum and tungsten mineral base in China,which has great prospecting potential.At the same time,the area is affected by the loess plateau,forming a large area covered by loess.In order to better carry out soil geochemical survey in western Henan,improve the geochemical exploration effect,and serve the prospecting work,the soil geochemical survey particle size test was carried out in the south slope of Xiaoshan,which is significantly affected by loess in western henan.7 graded by 42 samples(-4^+10 mesh,-10^+20 mesh,-20^+40 mesh,-40^+60 mesh,-60^+80 mesh,-80^+100 mesh,<100 mesh)samples,test results show that in the western soil geochemical survey in the areas affected by the loess sample size selection-20^+100 mesh is appropriate,the graded samples can reduce the interference of fine grained material in loess soil sample.
