DISTRIBUTION CHARACTERISTICS OF THE WEATHERINGCRUST-TYPE RARE-EARTH RESOURCES IN NANLING, CHINA
中国南岭风化壳型稀土资源分布特征

Based on the research on the distribution characteristics of the weathering-c rust-type rare-earth resources in Nanling in term of their elements, reserves, age, structure and geography, the author comes to the conclusion that the granite weathering-crust-type rare-earth resources predominate the weathering-crust-type rare-earth resources in the region and their Characteristics are high in element abundance, big in reserves, new in age, simple in tectonic conditions and wide in geographical distribution. Besides, there is. also occurrence of rare-earth minerals in the weathering crusts of volcanic rock and phyllite, thus negating the traditional concept that all the weathering-crust-type rare-earth minerals in Nanling are formed after the weathering of granites and broadening the ore-finding scope and the prospective reserves of rare-earth resources.
