香溪统与自流井统在利用出露很广,组成利用向斜和建南背斜两翼,在进行香溪统顶部铁矿层层位对比时,要求解决香溪统与自流井统的分界问题。根据我们利用找矿组工作的结果,我对它提出了一些初步意见。 总的说来,香溪统岩性是灰白色的,颗粒较粗,自流井统是绿黄色泥质的。但具体从那里分开意见还不一致。 The use of Xiangxi and Artesian wells in a wide range of occurrences makes use of the syncline and the Jiannan anticline two wings to resolve the boundary problem between the Xiangxi and the Artesian wells during contrasting the top of the Xiangxitong iron deposit. Based on the results of our work with the prospecting group, I made some preliminary comments about it. In general, the Xixi lithology is white-gray with coarse grains and artesian greenish-yellow shale. However, the specific opinion from there is not consistent.
