The diagenetic processes, noticed in carbonates of the Mughal Kot Formation, includes micritization, dolomitization
, iron cementation, cementation (isopach), mechanical compaction, chemical compaction (stylolitization) and fracturing (but most are filled).
Some patches of dolomitization
and shale were observed in the unit (Fig.
(b) Early synsedimentary fractures, fluid circulation probably coming from the compaction of underlying clays (Lower Cretaceous and Upper Jurassic) and associated dolomitization
. (c) Late Cretaceous tectonic reactivation and fluid circulation likely coming from the Sherwood Sandstone and resulting in breccia formation.
It seems that during Porkuni time besides sampling density also some local reasons (like shallow sandy sedimentation environment and secondary dolomitization
) affect the diversity.
of some up to 3 m OS intervals next to barren interlayers is also reflected in the elevated content of MgO and dolomite (Fig.
The strong diagenetic transformations, essentially dolomitization
, that affect most of the marine carbonates comprising the Triassic sequences of the Iberian Peninsula are the main reason for the lack of studies dating the succession based on [sup.87]Sr/[sup.86]Sr ratios.
The impact of geothermal activity has been invoked to explain the dolomitization
mechanism (He and Feng, 1996; Wang and Jin, 1997; Chen et al., 2012; Hao et al., 2012; Li et al., 2012; Shu et al., 2012; Huang et al., 2013; Tian et al., 2014).
In parts of Minnesota and western Wisconsin, diagenetic processes such as quartz syntaxial and potassium feldspar epitaxial overgrowths, hematite precipitation, dolomitization
, calcite precipitation, calcite dissolution, and a second hematite precipitation have variously altered the original texture of the sands of the Jordan Formation (Thomas, 1992; Runkel and Steenberg, 2012).
is one of diagenetic feature has been affected on this microfacies.
Some diagenetic processes, such as compaction, cementation, dolomitization
and bioturbation, were also observed in Amb Formation.
The diagenetic processes that have affected the Arab-D reservoir include dolomitization
, leaching and recrystallization, cementation, compaction and fracturing.
