Figure 8.
The gray, organic-rich layers with kerogen patches are interbedded with the yellow inorganic layers. High pressure in the organic-rich layers, generated in response to kerogen maturation, increases compressive stress in each inorganic layer from top and bottom. This compression causes rock failure and creates vertical microfractures in the inorganic layers. Vertical fractures also emanate from the spherical kerogen specks. Adapted from Chauve et al. (2020).
