The dolomitic part of K1 is characterized to be mudstone, mudstone to packstone
, beige, moderately hard to hard, crystalline to cryptocrystalline, have occasional pelloids, pebbles and shell fragments, have local mudcracks in mudstone, slightly argillaceous in parts, have thin layers of anhydrite and o have good to fair vuggy and intercrystalline porosity.
There are scattered bioclastic packstone
and grainstone horizons which commonly show fining upward (Wong, 2002); these represent deposition during brief storm events.
A mound in Lawrence County consists chiefly of packstone
and grainstone dominated by eclnirnoderrni ossicles amid fragments of fenestrate bryozoarns.
Palynofacies Lithology 1 Lime mudstone 2 Wackestone, Packstone
3 Coal 4 Siltstone, shale Palynofacies Characteristics 1 Predominantly amorphous organic matter ([greater than]90%), few marine microfossils and wood 2 Dominated by amorphous organic matter (50%), followed by black debris, brown-black debris, marine microfossils, wood, cuticles, and Sporomorphs in that order 3 Brown-black debris dominant (45%), followed by wood and black debris and sporomorphs 4 Variable numbers of all types of Palynodebris
5 meters upsection by the Texigryphaea oyster packstone
beds that typify the Walnut Formation (Adkins 1928; Flatt 1976).
The carbonate is of wacke-stone and packstone
and is locally silty and argillaceous.
These deposits include different textures ranging from wackestone to packstone
The classification of Dunham, 1962 divides limestone on the basis of texture into grainstone, packstone
, mudstone, wackestone and boundstone.
The stone is a light grey crinoidal packstone
that contains abundant coral macrofossils (Fig.
Oolitic grainstone and packstone
are restricted to the lowest portion of the outcrop (Fig.
The upper Fusselman is dominated by widespread thick, crinoidal grainstones, and lesser amounts of dolomitic wackestone to skeletal packstone
45 m, is the early bioherm facies developed as a crinoidal-oncoidal packstone
