Appendix A: Dunham's (1962) classification of carbonate rocks according to depositional texture
| Depositional texture recognizable | Depositional texture not recognizable (subdivided according to classifications designed to bear on physical texture or diagenesis) |
||||
| Original components not bound together during deposition | Original components were bound together during deposition, as shown by intergrown skeletal matter, lamination contrary to gravity, or sediment-floored cavities that are roofed over by organic or questionably organic matter and are too large to be interstices | ||||
| Contains mud (particles of clay and fine-silt size) | Grain supported | Lacks mud and is grain supported | |||
| Less than 10% grains | More than 10% grains | ||||
| Mudstone* | Wackestone | Packstone | Grainstone | Boundstone | Crystalline carbonate |
|---|---|---|---|---|---|
Dunham (1962) used "lime" as an adjective to differentiate between limestones and dolomites. Because none of the rocks in this study were dolomites, "lime" was deemed superfluous and was not used to modify the types of carbonate rocks.
*A terrigenous mudstone denotes in this publication a shalelike rock that does not display obvious laminae (i.e., not a limestone).
Appendix B: Folk's (1965) code for classification of calcite cement
- I. Mode of formation
- P: Passive precipitation
- D: Dlsplacive precipitation
- N: Neomorphism
- R: Replacement
- II. Shape
- E: Equant, axial ratio <1.5:1
- B: Bladed, axial ratio 1.5:1 to 6:1
- F: Fibrous, axial ratio >6:1
- III. Crystal size
- 7: Extremely coarsely crystalline, >4.0 mm
- 6: Very coarsely crystalline, >1.0 mm
- 5: Coarsely crystalline, >0.25 mm
- 4: Medium crystalline, >0.062 mm
- 3: Finely crystalline, >0.016 mm
- 2: Very finely crystalline, >0.004 mm
- 1: Aphanocrystalline
- IV. Foundation
- O: Overgrowth, in optical continuity with nucleus
- C: Crust, physically oriented by nucleant surface
- S: Spherulitic with no obvious nucleus
Example: PE2 is a passively precipitated, very finely crystalline, equant calcite cement.

Modifying terms
| Genetic modifiers | |||
|---|---|---|---|
| Process | Direction or stage | ||
| solution | s | enlarged | x |
| cementation | c | reduced | r |
| internal sediment | i | filled | f |
| Time of formation | ||
|---|---|---|
| Primary | P | |
 |
pre-depositional | Pp |
|
depositional | Pd |

|
small mesomold | smsMO | ||
|
microinterparticle | mcBP | ||
| *For regular-shaped pores smaller than cavern size. †measures refer to average pore diameter of a single pore or the range in size of a pore assemblage. For tubular pores use average cross section. For platy pores use width and note shape. |

| Abundance modifiers |
|---|
| percent porosity (15%) or ratio of porosity types (1:2) or ratio and percent (1:2) (15%) |
Construction of Porosity Designation
Any modifying terms are combined with the basic porosity type in sequence given below:
Genetic modifier + size modifier + basic porosity type + abundance
