Packstone.

Condensed packstone . Grain-supported, diagenetic texture due to compaction and pressure solution with partial grain suturing: some grain contacts are microstylolites; between grains there is micrite matrix. Skeletal grains are large benthic foraminifera (nummulitids, discocyclinids), coralline red algae, echinoderms and bryozoans. ...The packstone texture occurring in the lower part can be interpreted as resulting from gravity flows such as debris flows (Shanmugam and Benedict 1978; Sawyer et al. 2012).

Packstone.—Grain-supported muddy carbon­ ate rocks are termed packstone (PI. VI). Grain-support is generally a property of rocks deposited in agitated water, and muddiness is generally a property of rocks deposited in quiet water. A rock exhibiting both properties is peculiar, and it is well to have it isolated for further study.

facies and channel-form packstone facies attests to the autochthonous nature of these facies (Krivicich et al., 2014). The autochthonous nature of these facies is demonstrated further by the restriction of semi-articulated echinoids to these facies (Thompson and Ausich, 2016).

Based on the integration of the outcrop data, biostratigraphic and microfacies information, Wargal Limestone is suggested toFigure 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).
