| Recent researchers have divided the batholith longitudinally into two zones based on geochemical, geophysical, and lithologic differences. |
| Carbonate bedrock matrix heterogeny is often considered problematic in lithologic control. |
| Lithologic variability within the sandstone, specifically a finer-grained and mica-rich shallow zone, likely generates confined behavior. |
| In some cases, escarpments occur where there is no obvious lithologic or tectonic origin. |
| These variations provide a lithostratigraphy or lithologic stratigraphy of the rock unit. |
| He recognized two different fossil fauna assemblages in the limestone and the divided the limestone into two distinct lithologic units of Devonian and Mississippian age. |
