对开采中的黑矿矿床勘探来说,重要课题之一,便是如何预测该矿床的分布围,并能更有效地进行矿床外围勘探的问题。笔者等重视了黑矿矿床区域调查之际,依据矿床下盘酸性熔岩中低 Na_2O 晕确定勘探目标的一种方法,并将其试用到以矿床为中心的详细研究上面。其结果,不仅圈定了开采中的矿床的勘探范围,而且为今后调查找到很有前途的找矿标志。现将报告这一成果,望各位批评指正。
One of the most important topics for the exploration of black mineral deposits in the exploitation is how to predict the distribution of this deposit and to more effectively conduct the exploration of the periphery of the deposit. The author attaches great importance to the regional investigation of the HeiMing ore deposit, and based on the low Na2O halo in the acid sediment of the ore plate, a method of determining the exploration target was experimented to the detailed study centering on the ore deposit. As a result, it not only delineated the exploration area of the deposit under exploitation but also found promising prospecting indicators for future investigations. We will report on this achievement and hope you will correct your criticism.
