The uppermost part of the formation is an intraclastic, bioclastic sandy limestone (Fig. 2l, m). Based on palynology, vertebrate and invertebrate fossils, Bajocian to Early Oxfordian (160–170 Ma) age is given to the Samana Suk Formation [ 19 ].

This biozone is composed of gray massive bedding limestone and an alternation of gray medium and thick-bedded limestone. It is characterized by bioclastic peloidal wackestone–packstone and rudist floatstone (middle ramp), foraminifera intraclastic grainstone, and benthic foraminifera rudist debris packstone–grainstone …
Starting from the relatively deep-water depositional environment of dark shale and micritic limestone in the early stage of the Feixianguan Formation, the area experienced the deposition of grainstone (mainly oolitic limestone, followed by intraclastic grainstone and bioclastic grainstone), and ultimately evolved into a micritic dolomite and ...
Lithoclasts (see illustration above) are irregular fragments of limestones that were eroded and transported within or from outside of the basin of deposition. They are sometimes called extraclasts or detrital …

Intraclastic grainstone: Grain-support; Grains are primarily intraclasts, making up 50%–70% of the rock volume. It can be divided into conglomerate-sized, ... Interbedding of mudstone and thin argillaceous limestone above the drown unconformity of Msb6 at the Tumuxiuke (TMXK) Formation (known as the Saergan Formation in the …
Should intraclasts form >25% of the grains, then the rock is named an intraclastic limestone; if intraclasts are <25% and ooids are >25%, the rock is an oolitic limestone; …

List two specific characteristics that you could use to distinguish between marine (ocean or salt water) and nonmarine (freshwater) sedimentary deposits.
The intervening micritic limestone often found tapered and teared supplying clasts to the intraclastic layers. In contrast, conglomerates of subtype II are thicker (av. Thickness 35 cm), with scoured base and relatively low clast concentration.

LFA4 (Fig. 10 D) is characterized by intraclastic rudstone or floatstone lithofacies scouring the underlying argillaceous limestone, intraclastic wackestone, or packstone. In the vertical direction, the underlying lithofacies are matrix-supported lithofacies that represent a low-energy depositional background, whilst the overlying …

1. Intraclasts. Ooidal grainstone with a rounded clast of similar ooidal packstone/grainstone with micritized ooids and meniscus micrite that must have been rapidly lithified and eroded during storms. Thin section kindly provided by T. Geel, Vrije Universiteit, Amsterdam.
The intraclastic limestone lithofacies occurs in the uppermost part of the Sangdong section and in the middle part of the Nammyeon section (Fig. 1). Intraclasts are moderately sorted, and made of various carbonate rocks, mainly grain shoal carbonates such as oolitic grainstone and reworked intraclastic limestone. Ooids in the oolitic …
Four distinct rock samples were examined: bioturbated limestone, bioturbated siliceous limestone, bioclastic intraclastic sandstone, and quartz arenite, which were analyzed through thin-sectioning and scanning electron microscopy. Mechanical properties were determined through uni-axial compression testing and ultrasonic measurements, while a ...

These intraclastic limestone facies, sometimes referred to as 'anachronistic facies' by certain authors, contain flat-pebble conglomerates, breccia, and vermicular limestone [9,10,11]. The deposition of these anachronistic facies is the manifestation of related environmental events following the LPME [8,11].
Up-section, a succession of nodular, bioturbated limestone follows, containing rudist biostromes and rudist rudstone. The upper part is dominated by thin-bedded bio-/intraclastic limestone units including …
