工作区震旦系岩层分布很广,其中产有很多的铁矿,对它的研究就有很重大的意义。现在就我们在工作中的观察,稍加以总结,以供今后检查震旦纪铁矿参考。并且在今后的实际工作收集更多的资料,综合研究,总结出此类铁矿的生成规律。 此类铁矿产于震旦系矽质灰岩中,呈浅灰色——灰色,致密块状质地坚硬节理异常发育。多少甚至没有方解石石英脉,但有些还是可以见到的。地层产状不很明显,倾角中等。
Sinian work area is widely distributed rock formations, which produce a lot of iron ore, its research has great significance. Now we are working in the observation, a little summary, for future inspection Sinian iron ore reference. And in the future more practical work to collect data, comprehensive study, summed up the formation of such iron ore law. These iron ores are produced in Sinian siliceous limestone and are light gray-gray in color with dense, massive, hard-textured joints. Some are not even calcite quartz veins, but some can still be seen. Stratigraphy is not obvious, moderate dip.
