过去人们一直认为保康是沉积岩区,全是外生矿床,但经过一个月紧张的战斗,我们保康队在崇山峻岭之中依靠广大群众的支持与帮助,提供了不少值得注意的线索,保康石墨矿就是其中的一个。 矿之围岩:最外围是下志留纪的条带状黄绿色页岩,风化面含有铁质。石墨矿苗附近是黑色的页岩,比较坚硬,可能含灰质和矽质,初步确定其为下志留纪。 In the past, people always thought that Baokang is a sedimentary rock area, all exogenous deposits, but after a month of intense fighting, we Baokang team rely on the support and help of the masses in the mountains and mountains, providing a lot of noteworthy clues to Paul Kang graphite mine is one of them. Surrounding rocks of the mine: the outermost periphery is the banded yellow-green shale of the Lower Silurian, with the weathered surface containing iron. Black shale near the graphite miner, which is relatively hard, may contain gray matter and silicon, was initially identified as the Lower Silurian.
