Calcite flower development in areas of low-confining pressure in shale. Porosity development at calcite grain boundaries. Characteristic and consistent of infilling pores by calcite flowers.
Large pore within quartz rich shale. Pore was created as crustal fluids moved through the rock dissolving organic matter and potentially clays. Pore notably shows the development of large secondary pyrite crystals and dissolved organic content.
False color image of quartz proppant sand grains. Central mass shows aggregated grains of quartz and associated minerals. Porosity is noted between aggregated grains.
Image segregation analysis of feldspar rich shale. Segmentation analysis shows pronounced development of intergrain pores, in addition to more minor intragrain pores. Horizontal field width is approximately 50 μm.
Porosity development within the infilled chamber of a gastropod. (Chambers are predominantly filled with kaolinite, with intergrain pores; smaller chambers are noted to be filled with organic material containing intragrain pores.)
Intergrain porosity development at grain boundary of fusinite organic material.
Intragrain pores within annealed pyrite framboids.
