| 摘 要： | 目前山东省已发现稀土矿床（点）7个，查明轻稀土资源储量77余万吨。省内稀土矿床的成因类型主要包括碱性岩系列和花岗岩系列两大类，碱性岩系列稀土矿床的赋矿围岩主要为中生代产出的正长（斑）岩体、碳酸岩及云母岩等，花岗岩系列稀土矿床的赋矿围岩为中生代花岗伟晶岩。本文总结了山东省稀土矿资源现状及开发利用程度，重点论述了碱性岩系列和花岗岩系列两类稀土矿床的典型矿床地质特征，提出在山东省内进行同类型稀土矿床的找矿方向，为稀土矿床勘查提供参考。

| Abstract: | There are totally 7 rare earth element (REE) deposits (mineralized spots) in Shandong province at present, and the proven reserves of light REE is 465900t. The genetic types of REE deposits in Shandong province mainly include alkaline rock series and granitic series. The surrounding rocks of the alkaline series of rare earth deposits are mainly syenite (porphyry), carbonatite and mica rocks produced in Mesozoic, while the surrounding rocks of the granite series of rare earth deposits are granitic pegmatite of Mesozoic. In this paper, present situation and the degree of development and utilization of REE resources in Shandong province have been summarized, and geological characteristics of two representative REE deposits for alkaline rock series and granite series have been discussed. The direction for prospecting the same type of REE deposits in Shandong province has been pointed out. It will provide some references for the exploration of REE deposits in the future. |
