Color Cathodoluminescence 2

Sandstone sample from unknown formation, probably Strawn, Fort Worth Basin. Mostly ankerite-filled almost macrofractures from sample RGB3932.5. A few spots (such as in the light-blue grain at the bottom) are filled with quartz, mostly macros are calcite filled. Elsewhere in the t-section there is crack-seal texture in the carbonate indicating that in this sample at least some of the carbonate is syn-kinematic. Larger fractures are carbonate-filled, smaller ones, such as the one on the center right, are quartz-filled.
