| Local order: | top to bottom | ||||
| Stratigraphic resolution: | bed | ||||
| Stratigraphy comments: Lower Heath. JA: late Chesterian is Serpukhovian according to Mii et al. 1999 (GSA Bull 111:960-973) | |||||
Lithology and environment
| Primary lithology: | black,gray lithified calcareous "limestone" | ||
| Secondary lithology: | siltstone | ||
| Lithology description: limestone, dark gray to black, dense to finely crystalline, well bedded, locally laminated; 2ft layer 3ft above base is siltstone, gray, calcareous, poorly exposed, shaly. | |||
| Environment: | offshore | Tectonic setting: | cratonic basin |
| Geology comments: Some of the upper Heath MAY be estuarine/non-marine as noted by the author. These localities contain wood and other plant fragments, are non-calcareous and contain no marine fossils. These localities have been omitted by me [MS]. | |||
