| 中文摘要: |
| 粤北地区成矿地质条件优越，矿产资源种类齐全，其中铅锌、铀、钨、稀土等矿产资源列居本省前列。到目前为止，全市已查明资源储量的有 56种。但对稀土矿评价工作投入较少，随着近年来对稀土调查工作的深入，发现粤北地区稀土资源丰富，主要赋存于花岗岩风化壳和灰岩风化壳中。本文根据区域稀土成矿地质特征，划分了 6个找矿远景区:九峰—诸广山岩体、贵东岩体、大东山岩体、佛岗岩体北缘、连阳岩体、禾尚田灰岩区。在花岗岩岩体边缘及灰岩风化壳厚大且构造运动强烈区域找稀土矿，相信会取得很好找矿成果。 |

| There is an excellent geological condition of metallogenesis and a great variety of mineral resourcesin northern Guangdong，Whitch lead zinc uranium tungsten and rare earth mineral resources at the forefront of theGuangdong Province. Up to now，the reserves of 56 kinds of mineral resources have been confirmed in the area. However，little attention has been paid to the evaluation of rare earth ore. With the gradual investigation of rareearth in recent years，it is found that rare earth resources are abundant in northern Guangdong，which mainly existin granite weathering crust and limestone weathering crust. According to the geological characteristics of regional rare earth mineralization，six prospecting potential areas are divided:Jiufeng-Zhuguangshan pluton，Guidong pluton，Dadongshan pluton，the north edge of Fogang pluton，Lianyang pluton，and Heshangtian limestone. Therare earth deposits in the margin of granite pluton and the limestone thick weathering crust with strong tectonicmovement will certainly get good results. |
