Skeletal packstone

Skeletal packstone–floatstone (SPF) Gray skeletal packstone to floatstone with visible fine sand-sized carbonate grains. In hand sample, facies SPF beds are more visibly grainy than the purple lime mudstone facies and contain a range of large skeletal clasts from 0 to 20%. Weathers to a tan color similar to facies HSP (Fig. 6 B).

From its base upsection, the formation is mostly subtidal in origin and emergent at its top, and consists of (1) deeper water carbonates, (2) major cycles of open shallow-marine mudstones grading up into skeletal packstone or rainstone, (3) minor cycles of dolomitized transitional open to restricted marine mudstone grading up into skeletal ...
