Abstract: In order to study mineral composition characteristics and genesis of the shale of Lower Cambrian Niutitang Formation in northern Guizhou,and propose a new method of shale brittleness evaluation for this area, the mineral compositions of Niutitang Formation shale in XY1 well in northern Guizhou were studied by means of thin section identification,scanning electron microscopy-energy spectrum analysis,cathodoluminescence,element scanning analysis,mineral quantitative X-ray diffraction analysis and triaxial compression test,and brittleness characteristics of shale were evaluated based on petrophysics and mineral composition. The results show that the minerals of Niutitang Formation mainly consist of quartz and clay minerals,and also contain a small amount of feldspar,carbonate minerals and pyrite,with volume fractions of 43.5%,30.3%,11.6%,8.3% and 6.2%,respectively. By analyzing the relationships of mineral content with elastic modulus and Poisson's ratio,it is considered that the lower part of Niutitang Formation is more brittle than the upper part,and the brittle minerals are composed of quartz,pyrite and carbonate minerals,with the volume fraction of brittle minerals of 41.7%-82.3%. The difference of sedimentary environment is one of the reasons for the difference in rock brittleness.

Key words: shale minerals, origin types, scanning electron microscopy, sedimentary environment, brittleness evaluation, Niutitang Formation, northern Guizhou
