a measure of how well fluid will flow through a rock
broken rock and mineral grains
mineral bounded by its own faces
pressure is main agent
arenite with > 50% feldpar
a general summary of a particular depositional system, involving many individual examples from recent sediments and ancient rocks
affects small volume of rocks
structures or minerals from parents rock that did not undergo metamorphosis when surrounding rock did
porosity developed developed when seiment is deposited
all changes undergone by a sediment after its initial deposition, exclusive of weathering and metamorphism
geographic area where sediments are/have accumulated
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
controls the kinds of materials that will be available as sediment, the source area from which sediment is derived
set of processes that produce textural and mineralogical changes between diagenesis and melting
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
caused mainly by heat
few, large grains that occur when nucleation is inhibited
crystal that gets its outline from neighbouring crystals
reorganization and movement of grain boundaries, most obvious in monomineralic rocks
very closely spaced alignment of minerals produced by directional stress
rocks that have undergone a change in form
mainly this section scale, involve grain to grain relationships
the finer-grained material that occurs between the coarser grains in a rock
grain boundaries do not equal crystal faces
an indication of the efficiency of the transport medium, it is evaluated on the amount of matrix and the roundness & sorting of clasts
exfoliation, frost acation, abrasion
visible on hand sample scale
neocrystallization and recrystallization as temperature and pressure increase, typically during burial
chemically precipitated material that fills the spaces between framework grains in sedimentary rocks
metamorphism dominated by chemical changes
porosity developed during diagenesis
crushing and breaking of rocks
formation and growth of new minerals, most common, same as diagenesis but at higher temperatures
small scale effect of metasomatism
affect large volume of rocks
pre-metamorphic rock
a sedimentary rock dominated by particles of less than 0.004mm in diameter, lacking in laminations and >75% matrix
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
preferred linear alignments of elements such as minerals, bundles of microfolds, striations or grooves, or intersections of 2 planar features
platy and acicular minerals intergrown in a nonfoliated, interlocking and locally radiating manner
most commonly H2O or CO2, induce changes in rock, alter mineralogy
type of sandstone characterized by a matrix of between 15 and 75%
structures that prevade rock
3rd weathering method, hydration etc.
arenite with >50% lithic rock fragments
moss growth, tree roots
increase of temperature with depth
results from radioactivity and magma emplacement
correlates to depth of burial, tensions, compression or shear
type of sandstone with matrix minerals comprising 15% or less of the rock
neo & recrystallization as temperature and pressure decrease, typically during uplift or exhumation
a special type of foliation where the planar features are closely spaced and regular, imparting a splitting property to rocks
