WebThin-bedded, graded skeletal packstone to fine-grained grainstone 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. WebJul 1, 2003 · Carbonates are understood to be the most difficult lithology to which to apply quantitative seismic analysis, because of their heterogeneity deriving from their complicated depositional systems and diagenetic processes. We were able to study a fairly complete set of property data for Cretaceous carbonates, consisting of wackestone, packstone and …
The presence of any primary carbonate mud precludes a classification of grainstone. A study of the use of carbonate classification systems by Lokier and Al Junaibi (2016) highlighted that the most common source of confusion in the classification of grainstone was to misidentify fine-grained internal micrite, generated by in-situ processes, as clay–silt grade sediment - thus resulting in the misidentification of grainstone as packstone. Failure to correctly determine the si… WebAug 1, 2024 · The heterogeneous incorporation of mud matrix (Pathways B, C and D; Fig. 7) account for the use of expressions like packstone-grainstone by carbonate petrologists (e.g. Pomar, 2001; Mallarino et al., 2002; Pomar and Hallock, 2007) or wackestone-packstone (Al-Aasm et al., 2009) hinting to the presence of hybrid textures.
