Based on the qualitative and quantitative analyses of the shale samples from the field outcrops and well cores,this paper studies the characteristics and significance of mineral compositions in the Lower Cambrian black shale gas reservoir from the Xiuwu basin,Jiangxi,China.The results show that the major components of the Lower Cambrian Wangyinpu Formation and Guanyintang Formation black shale are clay minerals and quartz,with an average content of 25.4% and 58.63%,respectively,and the minor components are feldspar and pyrite,with an average content of 2.5%and4.68%,respectively.In addition,the average content of the other minerals such as calcite,dolomite,gypsum,and so on is less than 5%.The mineral components characteristics of the Lower Cambrian black shale from Xiuwu basin are both similar and difference from the Barnett shale and the Longmaxi Formation shale.Furthermore,the paper discusses the sedimentary environments,the organic material evolution and the shale reservoirs according to the characteristics of the mineral components in the Lower Cambrian shale from the Xiuwu basin.The result shows that the mud shale thickness of this set of shale with quartz component50%is almost 50 mwhich is an ideal horizon for exploration and exploitation.
