Petrographic analysis shows a leached skeletal packstone texture. Evidence of leached pelloidal matrix is observed, along with unidentified skeletal grains and fragments.The results revealed 15 lithofacies that have been further grouped into 7 lithofacies associations 5 of which are carbonates and include (1) interbedded dolostone and evaporates, (2) microbialite buildup, (3) ooid-dominated grainstones, (4) burrowed skeletal peloidal wackestone-packstone and (5) mollusc-dominated wackestone-packstone.Spiculite wackestone/packstone. ========= SMF 2: Microbioclastic peloidal ... skeletal grains.

Three depositional cycles included within Yamama Formation, top cycle comprises inner ramp facies (oolitic grainstone), middle-ramp (packstone, wackestone), and the third bases cycle outer ramp (chalky micrite and gray …

Embry and Klovan modification of the Dunham’s (1962) biologic classification of organically bound rocks.“Floatstone” replaces Dunham’s “packstone”; the term “rudstone” replaces grain-supported biogenic limestones, and other organically bound rock are termed “bafflestone,” “bindstone,” or “framestone,” depending on the character of the organic …The following rock sample shows a transitional set of graded beds showing a lower packstone type bed with larger skeletal pieces and a fine-grained matrix. This is overlain by a coarser-grained, skeletal grainstone which shows a higher degree of sorting and physical breakage. The Mission Canyon Formation is a regressive, shoaling-upward carbonate to anhydrite sequence deposited in a slowly shrinking epeiric sea. From its base upsection, the formation is mostly subtidal in origin and emergent at its top, and consists of (1) deeper water carbonates, (2) major cycles of open shallow-marine mudstones grading up into skeletal packstone or rainstone, (3) minor cycles of ...HST of sequence 3 is a shallowing-upward sequence of nodular skeletal wackestone/packstone (Calloway Creek-Grant Lake limestones), capped by the thin Tate silty dolomite ( Figure 5).

AP-III is a dark-gray spatially discontinuous skeletal grainstone to packstone that laterally grades into a skeletal packstone to wackestone. It locally developed overhangs, rips-ups, and hardground on its upper surface.Skeletal packstone and grainstone facies (Fig. 4 K, Table 1) forms 0.1–1.8 m thick beds in the marginal parts of the basin; these sheets thin and/or pinch out against muddy carbonates downdip. The packstone-grainstone facies consist of moderately sorted, medium-sand to granule size skeletal and non-skeletal grains. Compaction seams in the ...The MFS is at the base of the non-fossiliferous lime mudstone containing abundant wispy kerogenous laminae in more basin-central positions. Locally, this mudstone rests on thin skeletal packstone sheet or thicker skeletal wackestone-floatstone. Updip, the MFS is at the base of laminated dolomite that occurs on top of a thin skeletal packstone.
