| 1. Double check site/core/hole |
| 2. Describe sediment/rock type: |
| a. Estimate proportion of carbonate vs. siliciclastic sediment (e.g., 20% clay and 80% carbonate) |
| b. Identify main constituents (e.g., skeletal, nonskeletal, quartz) |
| c. Assign principal name (e.g., skeletal grainstone, grainstone with clay) |
| d. Add size modifier if necessary (e.g., silt-sized) |
| e. Estimate dolomite content |
| 3. Describe color |
| 4. Describe bioturbation |
| 5. Describe fossils and ichnofossils |
| 6. Describe the consolidation: |
| Extreme = impossible to scratch or break |
| Strong = scratches or breaks with difficulty |
| Moderate = scratches or breaks easily |
| Poor = firm, resistance to finger pressure, reduced water content |
| Unlithified = soft with little strength, easily deformed, high water content |
| 7. Describe sedimentary structures |
| 8. Describe sorting |
| 9. Qualitative description of porosity |
| 10. Describe core disturbance |
| 11. Provide a record of all samples taken (e.g., photos, thin sections, smear slides) |
| 12. Assign minor modifiers (e.g., bioclast type) |
| 13. Describe facies and downcore changes in facies (e.g., Pelagic, Hemipelagic, Neritic) |
| 14. Circle your initials |
| 15. Repeat procedure with the next core |
