Cementation exponent (m) versus depth
General Atlantic WIW #1-A Tjaden, Spivey-Grabs Field
Cementation exponents decrease with depth from surface to bioclastic wacke-grainstone interval
Below bioclastic wacke-grainstone interval m in autoclastic cherts is high and decreases with depth again
Patterns in m may reflect:
- Systematic changes in pore type and/or
- Influence of paleo-perched water table
* m increase with increasing vug and mold content?
