鲁西地区稀土矿成矿模式及矿床成因探讨

Metallogenic Model and Genesis of Rare Earth Deposits in Western Shandong Province

摘要:

鲁西地区是稀土矿的重要产地，鲁西稀土矿成因类型为与碱性岩—碳酸岩有关的岩浆热液型，从南往北依次分布有微山郗山稀土矿、薛城关帝庙稀土矿、兰陵龙宝山稀土矿、莱芜胡家庄稀土矿和淄博八陡稀土矿。该文选取微山郗山稀土矿和莱芜胡家庄稀土矿作为鲁西地区稀土矿典型矿床，论述了典型矿床的地质特征、矿物特征，从矿床的成矿时代和物质来源入手，总结了成矿要素，建立了成矿模式，进行成因探讨，为鲁西地区稀土的找矿工作提供指导。

Abstract:

Western Shandong Province is an important producing area of rare earth deposits. The genesis of rare earth deposits in western Shandong province is magmatic hydrothermal type related to alkaline rock carbonatite. There are Chishan rare earth deposit in Weishan, Guandimiao rare earth deposit in Xuecheng, Longbaoshan rare earth deposit in Lanling, Hujiazhuang rare earth deposit in Laiwu and Badou rare earth deposit in Zibo from south to north. In this paper, choosing Xishan rare earth deposit in Weishan and Hujiazhuang rare earth deposit in Laiwu as the typical rare earth deposits in western Shandong, geological characteristics and mineral characteristics of the typical deposits have been discussed. Starting from the metallogenic age and material source of the deposits, metallogenic elements have been summarized, metallogenic model has been established, and the genesis has been discussed. It will provide guidance for the exploration of rare earth deposit in western Shandong province.
