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.
