Abstract This article serves as an introduction to the papers dealing with braided river deposits in this volume. A lithofacies code erected earlier by the writer is expanded to include matrix-supported gravel, low-angle cross stratified sand, erosion surfaces with intraclast conglomerates, and massive mud deposits. The four vertical profile models erected by the writer are expanded to six. A new model, the “Trollheim type” is proposed, to include gravelly deposits characterized by abundant… Expand

A Pleistocene sandur in western Norway: facies relationships and sedimentological characteristics
At Godoya near Alesund sequences of unconsolidated fine sand and silt below two till beds are interpreted as remains of a sandur. Two facies sequences dominate: One comprises erosional scoursExpand
Fluvial facies model of the Ganga River sediments, India
Abstract The river Ganga flows from the northwest to the southeast, following the lineaments developed in response to the Himalayan tectonics. Ganga sediments show a large number of faciesExpand
Lithofacies variations within sandur deposits: the role of runoff regime, flow dynamics and sediment supply characteristics
Abstract The Icelandic sandur plains have for long acted as classic sites for models of braided river behaviour and of associated lithofacies assemblages. However, many of the Icelandic sandurs areExpand
Lithofacies associations and channel flow characteristics associated with a Unit Bar of the Brahmaputra River in Dibrugarh, Assam, INDIA
Sedimentation in a fluvial system leads to the formation of bars with varied morphology, bedform features and internal stratification. These features bear imprints of the hydrodynamic conditionsExpand
Facies and fluvial architecture of a high-energy braided river: the Upper Proterozoic Seglodden Member, Varanger Peninsula, northern Norway
Abstract The Seglodden Member (Late Proterozoic), as studied in two areas of the Varanger Peninsula, northern Norway, is dominated by sand-rich braided river deposits. A quantitative summary ofExpand
Lithofacies and depositional history of a Late Devensian ice-contact deltaic complex, northeast Scotland
Abstract The Late Devensian sediments, exposed at the Mill of Dyce near Aberdeen, were deposited in an ice-contact deltaic setting. Extensively deformed debris flows deposited close to the ice passExpand
