| Name | R_Sedimentary_Structure |
|---|---|
| Entity Type | Table |
| Description | A reference table that stores valid sedimentary structures. Sedimentary structures are generally not discernible in small rock fragments like cuttings. Sedimentary structures involve relationships between rock masses or fractions of rock components. This may include description of structures developed contemporaneously with deposition (syngenetic) like bedding. Otherwise, it may describe structures developed during burial (epigenetic) like solution brecciation. |

The material surrounding grains, particles, or minerals can be emplaced at various times. It forms mechanically when the rock is deposited or chemically during the burial history. Matrix consists of small detrital grains that fill interstices between larger grains at time of deposition (syngenetic). Cement is deposited as a chemical precipitate with burial (epigenetic). | No |
