Figure 2

Sketches of sample geometry. Blue lines indicate layers, red dashed lines represent mineral fabric orientation and black lines represent the fracture trace during fracture propagation. Also shown are the a 2D contour plots and 3D surface roughness values for tensile fractures induced in the large samples (a) H, (b) VV, (c) Halt, (d) VValt, (e) V and (f) Valt. In the center, a comparison of the full-width half-maximum (FWHM) of the micro-slope distribution parallel (y-direction hatched shading) and perpendicular (x-direction solid color) to the direction of fracture propagation.
