上扬子北缘川北地区结晶基底晶质石墨矿数据集

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: one map MapGIS, including 1 point-based file, 1 line-based file and 1 area-based file (*.wt, *.wl and *.wp)1, expressing basement structures in the area, graphite deposit distribution and sample locations; data in Excel sheets, including 2 type files *.xls, recording results from fixed carbon testing of samples and data from oxide testing.
