Crystalline-Basement Crystalline Graphite Deposit Dataset on the Northern Margin of the Upper Yangtze and North Sichuan

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 200m long, 6.7m wide, 4.9m 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.
