Compaction is, for example, an important diagenetic process in clay, which can initially consist of 60 % water.
12.
As a part of a sedimentary or metamorphic rock, fossils undergo the same diagenetic processes as does the containing rock.
13.
If the illite crystallinity is > 1.0, it corresponds with a metamorphic shallow diagenetic zone or zeolite facies.
14.
The effects of diagenetic recrystallization first must be accounted for, followed by analysis of lamination textures and deduction of possible accretion mechanisms.
15.
Illite crystallinity can be used to trace the low grade metamorphic transition from zeolite facies to greenschist facies ( diagenetic zone to epizone ).
16.
The growth types termed diagenetic and hydrogenetic reflect suboxic and oxic growth, which in turn could relate to periods of interglacial and glacial climate.
17.
The breccia consists of fragments of white to dark gray cherty material, quartz-rich sandstone, diagenetic cherty nodules, and 40Ar / 39Ar method.
18.
They are linked to the uplift, erosion and surface weathering of previously deposited sediments and require conditions similar to primary and diagenetic red beds for their formation.
19.
As such, isotopic analysis makes use of the more resistant phosphate groups, rather than the less abundant hydroxyl group or the more likely diagenetic carbonate groups present.
20.
If the illite crystallinity values fall in the 0.42-1.0 ?? range, it corresponds with a metamorphic deep diagenetic zone or zeolite facies.
