Journal ArticleDOI
TL;DR: The Ganges and Brahmaputra rivers combined have formed one of the largest deltas in the world, comprising some 23,000 sq. miles as discussed by the authors, and the large discharge and heavy sediment load cause the rivers to be extremely unstable, and the channels are constantly migrating laterally.

1,030 citations


Journal ArticleDOI
TL;DR: The sediment budget for a stretch of coast along a barrier chain is calculated through use of historical records, covering a time span of nearly 100 years, mapped short-term changes, and estimates of volume changes caused by physical processes as discussed by the authors.

94 citations


Journal ArticleDOI
TL;DR: In this article, it is suggested that the former facies is aeolian, and comparison with the internal structures of present-day a eolian dunes in the White Sands Desert, New Mexico, enables features of dome-shaped and, to some extent transverse, dunes to be recognized.

52 citations


Journal ArticleDOI
TL;DR: In this article, the relationship of fossils to structures and mineral concentrations in most of these concretions illustrates the significance of organic decomposition and the resultant gases in very early diagenesis.

Journal ArticleDOI
TL;DR: The Palaeogene deposits of northeast Kent are approximately 700 ft. thick and consist of unconsolidated clays and loamy sands, which are mainly marine in origin this article.

25 citations


Journal ArticleDOI
TL;DR: The Taormina Formation as discussed by the authors consists of a thick dolomite sequence of Middle and Late Triassic age, which can be divided into three facies: White Dolomite, Tan Dolomites and Stromatolitic Dolomsite.

21 citations


Journal ArticleDOI
TL;DR: The Buelandet-Vaerlandet Formation as mentioned in this paper is the oldest Devonian breccia, conglomerate, and sandstone formation known to exist in the world, and it has a maximum thickness of 3,400 m.

18 citations


Journal ArticleDOI
TL;DR: This article showed that all of the pelitic zone (zone ρ of Bouma, 1962) is deposited by turbidity processes and the graptolites can be shown to be oriented, to the highest horizon, in a direction equivalent to the direction of emplacement of the underlying turbidite (as determined from sole markings and internal structures).

Journal ArticleDOI
TL;DR: The Tortonian deposits in northwestern Bulgaria show a great variety of structures which are divided into three main classes as discussed by the authors : structures formed during the deposition of gypsum and includes laminae and layers resulting from chemical precipitation and/or mechanical replacement of particles.

Journal ArticleDOI
TL;DR: Sedimentary material from the floor of the Queensland continental shelf, as well as beach-rock and reef-rock from inner and marginal shelf reefs of the Great Barrier Reef, have been dated by 14 C methods as mentioned in this paper.

8 citations


Journal ArticleDOI
TL;DR: The sedimentology of the Simla Series is practically unstudied as mentioned in this paper, and the primary sedimentary structures, vertico-lateral variation of the sediments, etc., in greater detail.
