| exfoliation, frost acation, abrasion | |
| an indication of the efficiency of the transport medium, it is evaluated on the amount of matrix and the roundness & sorting of clasts | |
| a sedimentary rock dominated by particles of less than 0.004mm in diameter, lacking in laminations and >75% matrix | |
| grain boundaries do not equal crystal faces | |
| very closely spaced alignment of minerals produced by directional stress | |
| results from radioactivity and magma emplacement | |
| a special type of foliation where the planar features are closely spaced and regular, imparting a splitting property to rocks | |
| preferred linear alignments of elements such as minerals, bundles of microfolds, striations or grooves, or intersections of 2 planar features | |
| affects small volume of rocks | |
| arenite with >50% lithic rock fragments | |
| neo & recrystallization as temperature and pressure decrease, typically during uplift or exhumation | |
| broken rock and mineral grains | |
| rocks that have undergone a change in form | |
| 3rd weathering method, hydration etc. | |
| few, large grains that occur when nucleation is inhibited | |
| controls the kinds of materials that will be available as sediment, the source area from which sediment is derived | |
| correlates to depth of burial, tensions, compression or shear | |
| mineral bounded by its own faces | |
| porosity developed during diagenesis | |
| type of sandstone characterized by a matrix of between 15 and 75% | |
| caused mainly by heat | |
| caused mainly by deviatoric stress | |
| a body of rock characterized by a particular combination of lithology, physical and biologoical structures that are different from the bodies above, below and laterally adjacent | |
| porosity developed developed when seiment is deposited | |
| most commonly H2O or CO2, induce changes in rock, alter mineralogy | |
| pre-metamorphic rock | |
| crushing and breaking of rocks | |
