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