The physical character of subaqueous sedimentary density flows and their deposits
Tập 48 Số 2 - Trang 269-299 - 2001
Thierry Mulder, Jan Alexander
The complexity of flow and wide variety of depositional processes operating in subaqueous density flows, combined with post‐depositional consolidation and soft‐sediment deformation, often make it difficult to interpret the characteristics of the original flow from the sedimentary record. This has led to considerable confusion of nomenclature in the literature. This paper attempts to clarif...... hiện toàn bộ
Fluvial responses to climate and sea‐level change: a review and look forward
Tập 47 Số s1 - Trang 2-48 - 2000
Michael D. Blum, Torbjörn E. Tornqvist
SummaryFluvial landforms and deposits provide one of the most readily studied Quaternary continental records, and alluvial strata represent an important component in most ancient continental interior and continental margin successions. Moreover, studies of the long‐term dynamics of fluvial systems and their responses to external or ‘allogenic' controls, can play im...... hiện toàn bộ
A REVIEW OF THE ORIGIN AND CHARACTERISTICS OF RECENT ALLUVIAL SEDIMENTS
Tập 5 Số 2 - Trang 89-191 - 1965
J. R. L. Allen
SUMMARYRecent alluvial sediments are reviewed with respect to their geometrical, textural, structural and biological characteristics. These properties are related to the physiographic occurrence and hydraulic geometry of streams and to the dynamics of flowing water as controlling sediment transport‐deposition and stream morphological activities. Based on this data,...... hiện toàn bộ
Water escape structures in coarse‐grained sediments
Tập 22 Số 2 - Trang 157-204 - 1975
Donald R. Lowe
ABSTRACTThree processes of water escape characterize the consolidation of silt‐, sand‐and gravel‐sized sediments. Seepage involves the slow upward movement of pore fluids within existing voids or rapid flow within compact and confined sediments. Liquefaction is marked by the sudden breakdown of a metastable, loosely packed grain framework, the grains becoming tempo...... hiện toàn bộ
Basic types of stratification in small eolian dunes
Tập 24 Số 3 - Trang 361-387 - 1977
Ralph E. Hunter
ABSTRACTThe thinnest recognizable strata in modern eolian dune sands can be grouped into six classes. They are herein named planebed laminae, rippleform laminae, ripple‐foreset crosslaminae, climbing translatent strata, grainfall laminae, and sandflow cross‐strata.Planebed laminae are formed by tractional deposition on smooth surfaces at high wind ...... hiện toàn bộ
Lithofacies types and vertical profile models; an alternative approach to the description and environmental interpretation of glacial diamict and diamictite sequences
Tập 30 Số 3 - Trang 393-410 - 1983
N. Eyles, Carolyn H. Eyles, Andrew D. Miall
ABSTRACT Increased knowledge of modern glacial depositional environments has resulted in rapidly evolving classifications of glacial tills. These are based to a large degree on theoretical considerations of likely depositional processes. The classifications are sophisticated and more advanced than the establishment of simple field criteria whereby individual till fac...... hiện toàn bộ
Variability of deltaic processes in terms of sediment supply, with particular emphasis on grain size
Tập 40 Số 3 - Trang 475-512 - 1993
Geoff Orton, H. G. Reading
ABSTRACTShort term variability in delta form and process can be partly explained by the relative strength of hydraulic parameters such as river discharge, discharge variability, wave energy flux and tidal range. However, the calibre or grain size is also important. The amount, mode of transport and grain size of the sediment load delivered to a delta front have a c...... hiện toàn bộ
A simulation model of alluvial stratigraphy
Tập 26 Số 5 - Trang 617-644 - 1979
John Bridge, M. R. Leeder
ABSTRACTThe quantitative model presented simulates the development of a two‐dimensional alluvial sedimentary succession beneath a floodplain traversed by a single major river. Several inter‐related effects which influence the distribution of channel‐belt sand and gravel bodies within overbank fines are accounted for. These are (a) laterally variable aggradation, (b...... hiện toàn bộ
Spatial and temporal distribution of diagenetic alterations in siliciclastic rocks: implications for mass transfer in sedimentary basins
Tập 47 Số s1 - Trang 95-120 - 2000
S. Morad, Marcelo Ketzer, Luiz Fernando De Ros
SummaryThe spatial and temporal distribution of diagenetic alterations in siliciclastic sequences is controlled by a complex array of interrelated parameters that prevail during eodiagenesis, mesodiagenesis and telodiagenesis. The spatial distribution of near‐surface eogenetic alteration is controlled by depositional facies, climate, detrital composition and relati...... hiện toàn bộ
Rhizoliths in terrestrial carbonates: classification, recognition, genesis and significance
Tập 27 Số 6 - Trang 613-629 - 1980
Colin F. Klappa
ABSTRACTRhizoliths are defined as organosedimentary structures resulting in the preservation of roots of higher plants, or remains thereof, in mineral matter. They are abundant and characteristic features of Quaternary terrestrial carbonates (calcretes and aeolianites) from coastal regions of the western Mediterranean. Field and petrographic observations indicate t...... hiện toàn bộ
