| For petroleum engineering, this development is the most important aspect, especially when comparing limestone with dolostone sequences. |
| The canyon system cuts down through marine sandstone, siltstone and dolostone. |
| They sometimes are found together with dolostone concretions, barite nodules, or phosphatic nodules. |
| Matrix minerals of the dolostone septaria are ferroan dolomite, quartz, calcite, and pyrite. |
| The section consists of calcareous shale with intercalated sparse limestone beds, dolomitic shales, and some dolostone beds. |
| Phosphatic nodules, large dolostone septaria, iron sulfide nodules, and crystal-lined vugs are present. |
