云南省某鉛矿,是一个主要产于硷性火山岩中的巨大鉛矿。58年曾先后在矿区內开展了1:50000至1:2000的鉛量金属测量工作,地質效果良好,不仅能好、快、多、省地提出全区的远景評价资料,且能直接指导重型山地工程的設計及施工。其情况初步綜合如后。一、矿床地質情况簡述(图一) 本矿区地层簡单,均为侏罗三迭紀紅色岩系,並有少数第三、四紀层分布。由老而新簡列如表1。
A lead mine in Yunnan Province is a huge lead mine that is mainly produced in alkaline volcanic rocks. In 58 years, it has carried out 1: 50000 to 1: 2000 in the mining area of lead metal measurement work, the geological effect is good, not only can be better, faster, more, the province proposed long-term evaluation information, and can directly guide the heavy Design and construction of mountain project. The situation is initially summarized as follows. First, a brief description of geological conditions (Figure 1) The strata of the mine is simple, are the Jurassic Triassic red rock series, and a small number of the third and fourth strata. From the old and the new Jane as listed in Table 1.
