| Definition | Term |
|---|
| a general summary of a particular depositional system, involving many individual examples from recent sediments and ancient rocks | |
| exfoliation, frost acation, abrasion | |
| broken rock and mineral grains | |
| grain boundaries do not equal crystal faces | |
| porosity developed during diagenesis | |
| set of processes that produce textural and mineralogical changes between diagenesis and melting | |
| neo & recrystallization as temperature and pressure decrease, typically during uplift or exhumation | |
| a measure of how well fluid will flow through a rock | |
| affect large volume of rocks | |
| platy and acicular minerals intergrown in a nonfoliated, interlocking and locally radiating manner | |
| a size parameter used to describe the textures of clastic rocks by relating the variation in grain sizes within the rock, it affects porosity and permeability | |
| the finer-grained material that occurs between the coarser grains in a rock | |
| chemically precipitated material that fills the spaces between framework grains in sedimentary rocks | |
| moss growth, tree roots | |
| all changes undergone by a sediment after its initial deposition, exclusive of weathering and metamorphism | |
| geographic area where sediments are/have accumulated | |
| 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 | |
| few, large grains that occur when nucleation is inhibited | |
| crystal that gets its outline from neighbouring crystals | |
| very closely spaced alignment of minerals produced by directional stress | |
| porosity developed developed when seiment is deposited | |
| most commonly H2O or CO2, induce changes in rock, alter mineralogy | |
| mineral bounded by its own faces | |
| preferred linear alignments of elements such as minerals, bundles of microfolds, striations or grooves, or intersections of 2 planar features | |
| a process in which pressure is concentrated at the point of contact between 2 grains, causing the contact area to dissolve and allowing for subsequent migration of ions or molecule | |
| pre-metamorphic rock | |
| correlates to depth of burial, tensions, compression or shear | |
