摘　　要：陕西省洛南县驾鹿碳酸岩型稀土矿的含矿岩石主要由构造蚀变带内形成的石英方解石脉和锰方解石脉构成,这些脉体是稀土元素富集的重要载体。含稀土矿物主要为磷钇矿、独居石和氟碳钙铈矿等,稀土元素以轻稀土为主,但重稀土相对偏高,与之伴生的矿产有钼、铅、锰等。驾鹿稀土矿属于碳酸岩型稀土矿。区域内已发现的稀土矿床(点)数量众多,其中多数为碳酸岩型,这些矿床的形成和分布普遍受到断裂构造的控制,形成了与控制断裂走向一致的碳酸岩稀土成矿带,这些已发现的碳酸岩型稀土矿床(点)及其成矿带的展布地段,具备良好的成矿地质条件和丰富的找矿信息,具有较大的找矿潜力和勘探价值。The ore bearing rocks of the Jialu carbonate type rare earth deposit in Luonan County,Shaanxi Province are mainly composed of quartz calcite veins and manganese calcite veins formed within the tectonic alteration zone.These veins are important carriers of rare earth element enrichment.Rare earth minerals mainly include yttrium phosphate,monazite,and fluorocarbon calcium cerium ore.The rare earth elements are mainly light rare earths,but heavy rare earths are relatively high.Associated minerals include molybdenum,lead,manganese,etc.Jialu rare earth mine belongs to carbonate rock type rare earth ore.There are numerous rare earth deposits(points)discovered in the region,most of which are carbonate rock type.The formation and distribution of these deposits are generally controlled by fault structures,forming carbonate rock rare earth mineralization belts that are consistent with the controlling fault direction.These discovered carbonate rock type rare earth deposits(points)and their distribution areas have good geological conditions for mineralization and rich prospecting information,with great potential and exploration value.
