We examined the stratigraphy of alluvial fans formed at steep range front Southern Alps Te Taho, on north bank Whataroa River in central West Coast, South Island, New Zealand. The coincides with Alpine Fault, an Australian-Pacific plate boundary fault, which produces regular earthquakes. Our study revealed aggradation 100- to 300-year intervals. Radiocarbon ages and soil residence times (SRTs) ...

Abstract We describe the soils, stratigraphy, distribution and ages of alluvial fans in North Carolina Piedmont to understand factors contributing their formation this low relief, humid‐temperate setting. find that those (i.e., source basin area rock type; climate) parallel, but do not precisely mimic arid semi‐arid climate fans. Digital elevation model (DEM) field observations revealed about 2...

Abstract The sand bodies formed by braided fluvial fan deposits have a certain distinctiveness. They not only the characteristics of facies sandbodies but also follow distribution law alluvial bodies. variation that are present along and perpendicular to channel is relatively complex. Therefore, constraints in modeling process sand–mudstone this type reservoir essential. This study selects seco...

Mars' transition from an early "warm and wet" to the "cold dry" environment left fingerprints on geological record of fluvial activity Mars. The morphological mineralogical observations aqueous provided varying constraints condition duration liquid water martian surface. In this study, we surveyed mineralogy alluvial fans deltas investigated hydrated silica-bearing deposits associated with thes...

Based on geomorphic observations, we discuss lake-level fluctuations, alluvial deposition and river entrenchment in the Dead Sea–Wadi Araba area. The bulk of alluvium in the northern Wadi Araba was probably deposited before the Lisan period of lake transgression that started at about 70 kyears B.P. The lake reached a maximum elevation about 150 m below sea level (b.s.l.), possibly around 15 cal...
