Oligo-Miocene alluvial-fan evolution at the southern Pyrenean thrust front, Spain

Investigating the use of alluvial fan volume to represent fan size in morphometric studies

“…A literature survey was conducted to determine how the problem had been approached before, but methods for calculating the volume of fans have been presented in a limited number of previous studies. The approach that turned out to be most similar to that used here employs the simple formula for a segment of a cone (Church and Ryder, 1972;Church and Mark, 1980;Iso et al, 1980;Lloyd et al, 1998;Campbell and Church, 2003;Jayko, 2005), as illustrated in Fig. 4:…”

Sedimentary Processes, Environments and Basins – A tribute to Peter Friend: Introduction

“…The Spanish Pyrenees and the Himalayas provide excellent case studies of the interaction of thrust tectonics and fluvial sedimentation, themes on which Peter published a number of times (Abbasi & Friend, 1989Friend et al, 1989Friend et al, , 1999Lloyd et al, 1998). The Pyrenees is one of the case studies used by Vergés (this volume) in his review of thrust tectonics and fluvial sedimentation, which also draws on information from Iran and South America.…”

“…Peter recognized this in his papers from the Pyrenees (Lloyd et al, 1998) and the Himalayas (Abbasi & Friend, 1989White et al, 2002), which used provenance studies in proximal foreland basin deposits to unravel the evolution of part of the mountain belt. In this volume, one of Peter's Himalayan co-workers, Burbank (this volume), shows how single-crystal dating can be used to provide a record of orogenesis.…”

Source area and tectonic control on alluvial-fan development in the Miocene Fohnsdorf intramontane basin, Austria

“…Higher-gradient mountainous streams in the uplifted hinterland can transport coarse detritus to the faulted basin margin of a low-relief plain, where alluvial-fan deposition occurs (e.g. Lloyd et al 1998). The occurrence of outsized clasts of a few metres in diameter throughout the whole succession of the Rachau fan calls for a high-gradient, constantly exposed hinterland providing a mountainous source area.…”
