| very closely spaced alignment of minerals produced by directional stress | |
| metamorphism dominated by chemical changes | |
| geographic area where sediments are/have accumulated | |
| crushing and breaking of rocks | |
| visible on hand sample scale | |
| chemically precipitated material that fills the spaces between framework grains in sedimentary rocks | |
| mineral bounded by its own faces | |
| a general summary of a particular depositional system, involving many individual examples from recent sediments and ancient rocks | |
| rocks that have undergone a change in form | |
| small scale effect of metasomatism | |
| neocrystallization and recrystallization as temperature and pressure increase, typically during burial | |
| platy and acicular minerals intergrown in a nonfoliated, interlocking and locally radiating manner | |
| a measure of how well fluid will flow through a rock | |
| set of processes that produce textural and mineralogical changes between diagenesis and melting | |
| 3rd weathering method, hydration etc. | |
| affects small volume of rocks | |
| correlates to depth of burial, tensions, compression or shear | |
| type of sandstone with matrix minerals comprising 15% or less of the rock | |
| all changes undergone by a sediment after its initial deposition, exclusive of weathering and metamorphism | |
| pressure is main agent | |
| the finer-grained material that occurs between the coarser grains in a rock | |
| formation and growth of new minerals, most common, same as diagenesis but at higher temperatures | |
| results from radioactivity and magma emplacement | |
| crystal that gets its outline from neighbouring crystals | |
| preferred linear alignments of elements such as minerals, bundles of microfolds, striations or grooves, or intersections of 2 planar features | |
| type of sandstone characterized by a matrix of between 15 and 75% | |
| controls the kinds of materials that will be available as sediment, the source area from which sediment is derived | |
