鹤(壁)—林(县)地区,系指京广铁路以西,辉县以北的河南省范围。该区地势西高东低,河流自西向东流,所有河流均汇入卫河。属卫河一级支流者有:漳河、安阳河(洹河)、汤河、淇河等十一条河流。通过金刚石找矿工作,在漳河、安阳河、淇河等河流中发现了金刚石,并圈出以镁铝榴石为主的伴生矿物重砂异常,面积约千余平方公里,同时在鹤壁西山发现镁铝榴石亚相金伯利岩带。金刚石及其伴生矿物的来源尚未查清。但笔者根据鹤—林地区的地质条件和找矿成果分析,认为含金刚石的金伯利岩应产于龙尾岗—林县一带,其中龙尾岗—
Crane (wall) - Lin (county) area, refers to the west of Beijing-Guangzhou Railway, Hui County, north of Henan Province. The terrain is high in the west and low in the east. The river flows from west to east, and all the rivers are merged into Wei River. Wei River is a tributary: Zhanghe, Anyang River (Bahe), Tanghe, Qihe and other eleven rivers. Through the diamond prospecting work, diamonds were found in Zhanghe, Anyang River and Qihe rivers, and the anomalous sand associated with the magnesia was encircled by anomalous sand with an area of about 1000 square kilometers. At the same time, Discovery of alluvial subphase kimberlite belt. The origin of diamond and its associated minerals has not yet been identified. However, according to the analysis of geological conditions and prospecting results in Crane-Lin region, the author thinks that the diamond-bearing kimberlite should be produced in the area of Longwei-Linxian, among which Longwei-
