| 摘 要： | 上扬子北缘川北地区出露的基底地层发育双层结构，其中上层的褶皱基底早已发现尖山、坪河、庙坪等中—大型、超大型石墨矿；但是直到最近，才在下层的结晶基底后河岩群汪家坪岩组细粒石英岩中发现了石墨矿。该矿体长约200米，宽约6.7米，矿体平均厚度4.9米，矿石平均品位5.13%。矿物组合为：石英+石墨+云母+黄铁矿+赤铁矿。该成果在上扬子北缘地区的发现，扩大了该区域的找矿前景，为区内晶质石墨矿的找矿工作提供了新的方向，同时为四川巴中地区超大型晶质石墨矿基地建设提供了新的资源潜力保障。数据集包括Excel表格数据，2个*.xls类型文件，记录了样品固定碳测试结果和氧化物测试数据。

| Abstract: | The basement strata outcropping on the northern margin of the upper Yangtze and North Sichuan have developed a dual-layer structure, where medium-large and extra-large graphite deposits have been found at Jianshan, Pinghe and Miaoping etc., which are located on fold basements in the upper layer. Until recently, however, a graphite deposit is found in fine-grain quartzite of the Wangjiaping Formation, Houhe Group complex of the crystalline basement in its lower part. The rock mass is about 200 m long, 6.7 m wide, 4.9 m thick on average and 5.13% in average grade. The ore combination is quartz + graphite + mica + pyrite + hematite. This discovery on the northern margin of the upper Yangtze expands the prospecting foreground in the region, provides new opportunities to prospect crystalline graphite ores therein and gives a new guarantee in resource potential to build an extra-large crystalline graphite ore base in Bazhong, Sichuan. The dataset contains data in Excel sheets, including 2 type files *.xls, recording results from fixed carbon testing of samples and data from oxide testing. |
