摘要
晋北晚古生代煤系中的高岭岩,其主要类型和富集层是:(1)本溪组底部的铝土质高岭岩;(2)太原组夹矸高岭岩;(3)山西组夹矸高岭岩。根据不同层位高岭岩的岩石、矿物、地球化学特征的差异,分析了高岭岩可能的源岩性质。
The authors studied the petrology, mineralogy and geochemistry of kaolin rock in Late Paleozoic coal measures in northern Shanxi. The major types and accomudation horizons are: ① bauxitic kaolin rock at the base of the Benxi Formation, ② tonsteins in the Taiyuan Formation, and ③ tonsteins in the Shanxi Formation. The differences in petrology, mineralogy and geochemistry of different horizons are related to the genesis and source rocks of the rock.
