…and sparry carbonate cement (sparite) are collectively referred to as orthochemical carbonate because, in contrast to allochems, neither exhibits a history of transport and deposition as clastic material.

i. A descriptive term for the crystalline, microscopically transparent or translucent, interstitial component of limestone, consisting of clean, relatively coarse-grained calcite or less commonly aragonite, that either recrystallised from micrite that accumulated during deposition or was introduced later into porous sediments as a cement. It is …

Definition of sparite i. A descriptive term for the crystalline transparent or translucent interstitial component of limestone, consisting of clean, relatively coarse-grained calcite or aragonite that either accumulated during deposition or was introduced later as a cement.

Allochemical rocks have grains that may consist of fossiliferous material, ooids, peloids, or intraclasts. These are embedded in a matrix consisting of microcrystalline carbonate (calcite or dolomite), called micrite, or larger visible crystals of carbonate, called sparite.

Samples are given a two part name; the first part is the most abundant grain type (bio-, pel-, oo-, or litho-) and the second indicates the nature of the interstitial material (-sparite or -micrite).

Dec 19, 2023 · Sparry calcite cement (sparite): pore-filling component precipitated during deposition. Major Families Classification. Based on the relative proportions of matrix and pore-filling components surrounding the framework component, Folk defined three major families plotted on a triangular diagram (Figure 1).

Feb 25, 2025 · Microcrystalline carbonate mud and sparry carbonate cement (sparite) are collectively referred to as orthochemical carbonate because, in contrast to allochems, neither exhibits a history of transport and deposition as clastic material. Micrite can occur either as matrix that fills or partly fills the interstitial pores between allochems or as ...

Oct 26, 2000 · The rock formed is then composed only of allochems, held together by clear to translucent calcite crystals with rhombohedral cleavage (called SPAR or SPARITE) acting as a cement. The spar is precipitated from fresh or marine water percolating through the sediment after deposition, but before final cementation.

4 days ago · Sparite is the coarse crystalline calcite cement which fills pore spaces in many limestones after deposition, formed by the precipitation of calcite from carbonate-rich solutions passing through the pore spaces in the sediment.
