Moving to grain-supported fabrics, a grain-supported limestone containing 1% or more mud-grade fraction is a packstone whilst a grain-supported carbonate rock with …Geologically the Bagh Group of rocks were first studied by Dangerfield (), followed by Stewart (), who published a note on the geology of the Bagh area.The first fossil from the ‘Bagh Beds’ was discovered by Keatinge (), followed by a report of invertebrate body fossils and their community by Oldham from the Chirakhan area.These studies …The packstone class is divided into grain- and mud-dominated packstone because the petrophysical properties of grain-dominated packstone are according to grain size, whereas mud size controls the properties of mud-dominated packstone. Diagenetic reductions in porosity by cementation and compaction are reflected in the amount of interparticle ...

Home.The lower Thebes Formation includes remobilized slope deposits comprised of three main lithofacies: (i) matrix-supported conglomeratic debris flows and (ii) turbiditic pack-grainstones embedded within (iii) slope packstone deposits (Hirani, 2014); from here on we will refer to these simply as conglomerates, grainstones and packstones.The Thebes Formation is partially dolomitized within the ...Figure 9.1 A illustrates the summary of diagenetic and porosity characteristics of a carbonate ramp during a third-order sea-level lowstand under humid climatic conditions. Because of the gentle dip of the ramp-to-basin slope, lowstand prograding complexes, featuring high-energy grainstones, can commonly form seaward of the lowstand shoreline (Fig. 9.1 B).

Under the Dunham classification (Dunham, 1962 ) system of limestones, a packstone is defined as a grain-supported carbonate rock that contains 1% or more mud-grade fraction. This definition has been clarified by Lokier and Al Junaibi (2016) as a carbonate-dominated lithology containing carbonate mud (<63 μm) in a fabric supported by a sand grade (63 μm to 2 mm) grain-size fra…(PDF) Karakteristik batugamping Formasi Wapulaka dan pemanfaatannya ... ….
