QFL Composition
click on picture for larger version  Because the composition of this rock is dominantly quartz one might be inclined to call its QFL quartz. Technically, however, the breccia fragments are quartzite, a metamorphic rock. Therefore, we classify this as a lithic breccia. |
Description
Sawed slab of rock. Angular gravel particles in the granual size range (4-64 mm) with a quartz sand matrix. Breccia fragments are composed of quartzite (metamorphosed quartz sandstone). A close look at the composition of the breccia fragments will show the individual fused quartz sand grains that compose the quartzite.
