Figure 5.
(A) Most of the deposited kerogen specks become flattened ellipsoids because of increasing overburden weight during burial. A small fraction remains spherical in shape. (B) Elliptical and spherical kerogen specks are distributed in the organic matrix. The dh represents the distance between two kerogen specks, and dv is the vertical distance between microscopic kerogen layers. σh = horizontal stress; σv = vertical stress; H = kerogen height; Pp = pore pressure; Rk = kerogen radius.
