Abstract The overwhelming documentation of coarse-grained alluvial fans dominated by mass flow contrasts with the scarce accounts of finer grained, traction-dominated alluvial fans. To fill this gap, we present sedimentological and architectural data from a set of sand-rich, streamflow-dominated Pleistocene fans flanking the eastern Upper Valdarno Basin, Italy. The routing of sand-rich sediment resulted from the fast, intense weathering of the feldspar-rich, carbonate-deprived sandstone bedrock… Expand
Alluvial fan facies of the Qazvin Plain: paleoclimate and tectonic implications during Quaternary
The present research focuses on a detailed facies description and interpretation of five alluvial fans of the Qazvin Plain. Beside the tectonic activity that leads to the localization of the fans onExpand
Geology and geomorphology of alluvial and fluvial fans: current progress and research perspectives
Abstract Alluvial and fluvial fans are the most widespread depositional landforms bordering the margins of long-lived highland regions and actively subsiding continental basins, across a broadExpand
Planview style and palaeodrainage of Torridonian channel belts: Applecross Formation, Stoer Peninsula, Scotland
Abstract The sedimentary products of forty-three Neoproterozoic fluvial-channel belts are superbly exposed along the seaboard of Stoer Peninsula, Scotland, UK. The deposits belong to the ApplecrossExpand
Eocene Willwood Formation, Bighorn Basin, Wyoming, USA
10 The lower Eocene Willwood Formation of the intermontane Bighorn Basin, Wyoming, USA, is an 11 alluvial red bed succession with a sand content of ca. 20%-25%. The formation has been studiedExpand
The Impact of Reservoir Heterogeneities on High-Temperature Aquifer Thermal Energy Storage Systems. A Case Study from Northern Oman.
Abstract We conducted a geoscientific feasibility study for the development of a high-temperature thermal aquifer energy storage system (HT-ATES) outside the capital of Muscat, northern Oman. TheExpand

Distinctive characteristics of a streamflow-dominated alluvial fan deposit: Sanghori area, Kyongsang Basin (Early Cretaceous), southeastern Korea
Abstract In the northwestern part of the non-marine Kyongsang Basin (Early Cretaceous), conglomeratic deposits occur at intervals along the northern basin margin and grade basinward into interbeddedExpand
Stream‐dominated alluvial fan and lacustrine depositional systems in Cenozoic strike‐slip basins, Denali fault system, Yukon Territory, Canada
Ancient stream-dominated (‘wet’) alluvial fan deposits have received far less attention in the literature than their arid/semi-arid counterparts. The Cenozoic basin fills along the Denali faultExpand
Pre‐vegetation alluvial fan facies and processes: an example from the Cambro‐Ordovician Rozel Conglomerate Formation, Jersey, Channel Islands
Prior to the Silurian a lack of land vegetation is expected to have influenced the processes of sedimentation on alluvial fans, principally by causing increased rates of run-off and erosion in theExpand
Cause of dominance by sheetflood vs. debris‐flow processes on two adjoining alluvial fans, Death Valley, California
Two large, adjoining alluvial fans of the Panamint Range piedmont, Death Valley, California, are composed of different facies assemblages deposited by contrasting sedimentary processes. The AnvilExpand
Sediments and processes on a small stream-flow dominated, devonian alluvial fan, Shetland Islands
Abstract The main conglomerate type of a small Devonian alluvial fan in Shetland, northern Britain, is an inverse to normally graded framework-supported gravel. The sedimentological details of theseExpand
Recognition and significance of streamflow-dominated piedmont facies in extensional basins
Alluvial slopes are piedmonts characterized by parallel steam channels rather than alluvial fans. They are common landforms in extensional basins of the south-western United States but have receivedExpand
Pleistocene Lacustrine Fan Delta Deposits of the Valdarno Basin, Italy
ABSTRACT During the Early Pleistocene, mouth bar fan deltas formed on the northern margin of the shallow water lacustrine Valdarno Basin, which developed during the last phases of the NorthernExpand

Abstract Tertiary alluvial fan deposits along the margin of the Ebro foreland basin north of Huesca, Spain, are remarkable for the range of sedimentological and tectonic features preserved withinExpand
Role of vegetation in shaping Early Pennsylvanian braided rivers: Architecture of the Boss Point Formation, Atlantic Canada
Vegetation is a major driver of fluvial dynamics in modern rivers, but few facies models incorporate its influence. This article partially fills that gap by documenting the stratigraphy, architectureExpand
Alluvial fans and their natural distinction from rivers based on morphology
ABSTRACT Contrary to common contemporary usage, alluvial fans are a naturally unique phenomenon readily distinguishable from other sedimentary environments, including gravel-bed rivers, on the basisExpand
