... ABSTRACT: Epidote and chlorite are both low-grade metamorphic minerals that are widely distributed in deep granite geothermal reservoirs. Hot fluid circulation promotes the precipitation of epidote and chlorite coatings on natural faults and fractures and this can in turn exert control...

.... In this study, we evaluated the effects of different shapes and distribution densities of mineral grains in coal on failure mechanics using the numerical software 3DEC. The main aim of this study was to identify possible failure mechanisms influenced by mineral habit and frequency in coal. Exploring differences...

..., while Na, K, and HCO 3 mainly come from the leaching of feldspar minerals by mantle-derived CO 2 . Water hydrogen and oxygen isotopes indicate the source of atmospheric precipitation, while Rehai hot spring water shows an " 18 O shift". It is related to the mixing of magmatic water and the interaction...

... ABSTRACT: Geogenic gases often reside in intergranular pore space, fluid inclusions, and within mineral grains. In particular, helium-4 ( 4 He) is generated by alpha decay of uranium and thorium in rocks. The emitted 4 He nuclei can be trapped in the rock matrix or in fluid inclusions. Recent...
