Pore Structure Differentiation between Deltaic and Epicontinental Tight Sandstones of the Upper Paleozoic in the Eastern Linxing Area, Ordos Basin, China

Figure 8

The compaction characteristics of coal-measure sandstone. All the sections were selected from the Taiyuan Formation of well LXD-2, which is located in the central part of the study area, and the depths are marked. (a) Mica extrusion deformation; (b) lithic extrusion deformation; (c) closely arranged quartz particles are in linear contact; (d) closely packed quartz particle bump contact; (e) and (f) Mica pieces under scanning electron microscopy (SEM) bending deformation.
