Massive Diamictic Gravel

Its subunits are 3.1.1 Basal pebble and gravel 0-68 m Massive conglomerate beds few cm to 1 m thick containing quartite, shale, sandstone and carbonate clasts derived directly from the Mesooic bedrocks, which is best exposed on the Tetang village section

Predominantly massive to well-bedded tuffaceous marine siltstone with interbedded arkosic and basaltic sandstone. Includes conglomerate in King County and along north side of Olympic Peninsula. Minor lava flows and breccia in western Lewis County and eastern Grays Harbor County. Coal seams in central Lewis County and north-central Pierce County

Glacimarine processes affect about 20 of the global ocean today, and this area expanded considerably under cyclical full-glacial conditions during the Quaternary Fig. 1 Dowdeswell et al. 2016 b . Many of the submarine landforms produced at the base and margin of past ice sheets remain well preserved on the seafloor in fjords and on high-latitude continental shelves after the retreat of

This paper reports on geoarchaeological work conducted at the site of Isturit during the 1996-1997 and the 2000-2005 excavations. The study of geomorphological context and sedimentary deposits both outside and inside the karstic block permit the main evolutionary phases to be described.The karstic system comprises three stepped levels, which are linked to downcutting stages of the Arberoue

Clay-poor lahars also called non-cohesive lahars, generally consisting of gravel- and sand-sied clasts, originate as water oods that entrain material. Flood waters leading to the formation of clay-poor lahars have been produced during lake breakout Pierson, 1999 Pringle

In LF-A4b, massive and conglomeratic rocks of LF 10, LF 11.1, LF 12.4, and LF 13.2.2 alternate with finer-grained siliciclastic deposits of LF 7.1 and LF 8.2. In addition, massive siltstones LF 3.1 are locally present. Massive sandstone laterally passes into 3-D trough cross-bedded sandstones and the base of the coarse units is mostly erosional

Abstract. The East Antarctic Ice Sheet discharges into the Weddell Sea via the Coats Land ice margin. We have used geophysical data to determine the changing ice-sheet configuration in this region through its last glacial advance and Holocene retreat and to identify constraints on its future stability. Methods included high-resolution multibeam bathymetry, sub-bottom profiles, seismic

Most of the gravel is 1.3 to 2.5 cm 0.5-1.0 in in diameter, but pieces as long as 10 cm 4 in are present. The gravel is composed of quart with small amounts of black chert and quartite. Clay commonly occurs as discrete, thin, discontinuous beds, is dark gray where unweathered, white or red where weathered

Core JM0586GC consists of black homogenous mud on top of unsorted gravel in a matrix of dark, sandy mud devoid of foraminifera and macrofauna. The lower unit is interpreted as a diamict in core NP0586GC and as a mixture of diamictic and glacimarine deposits in cores JM1010GC, JM1012GC, and HH121209GC

Sedimentologic and geomorphic evidence indicates that the liquefied sediment was transported as a hyperconcentated flow, possibly above a basal carpet of coarse diamictic sediment that behaved as a debris flow

Both lithofacies contain diamictic sandy-clayey gravels, usually massive to crudely bedded, which fill narrow and relatively shallow erosional channels forming palaeochan- nel-like bodies. The lithofacies Gmsb contains addition ally several large boulders, with diameter up to 1.8 m, and

Unit 4 is a clayey, silty massive diamicton that ranges in thickness from a few dm up to 1.5 m Figs. 6, 8. It contains shell fragments and occasional whole shells, as well as gravel clasts 15 cm scattered throughout the unit. A clast-rich horion occurs in the lower part
