Fluvial siliciclastic rocks bracketing the Cretaceous-Paleogene (K-Pg) boundary in San Juan Basin, New Mexico (USA), provide records of regional fluvial and tectonic evolution during Laramide orogeny. Petrographic analyses sandstones from Upper Cretaceous Fruitland Formation Kirtland Paleocene Ojo Alamo Sandstone Nacimiento show that rivers depositing these sediments were sourced areas where un...

The Maroni River, South America, is a tropical estuary encased in narrow lower valley with limited area of estuarine tidal flat development, and displays channel large downstream-migrating sandy bedforms linked to sand-filled shallow mouth. sand-rich nature the River reflects significant fluvial bedload supply, among rivers lowest suspension-sized sediment load world. During dry season, shows h...

In tropical and sub-tropical mixed siliciclastic–carbonate depositional systems, fluvial input in situ neritic carbonate interact over space time. Despite being the subject of many studies, controls on partitioning sediments remains controversial. Mixed sedimentary records, from Ashmore Trough shelf edge slopes (southern Gulf Papua), are coupled with global sea-level curves anchored to Marine I...

A seismic volume of a certain stratigraphic layer may be decomposed into components for channel analysis. In the first case study of stratigraphic interpretation, the relative amplitude of the first component outlines the channel. The relative amplitude of the second component discovers different lithological or stratigraphical features inside the channel. The relative amplitude of the third co...

The Guadix Basin developed as an endorheic depression during the Upper Miocene–Upper Pleistocene. Its principal palaeogeographical characteristics are a large lake in the eastern sector, an axial fluvial system and two fluvial systems transverse to it in the western sector. The uplift of a central sector of the Betic Cordillera during the Upper Pleistocene affected the study area, causing north...

The widespread urbanization of the corridor of the Sarno River has drastically modified the environment of this fluvial system. The aerial recognitions show that “the river continuum” was replaced by a continuum of town centres developed along the course of the Sarno River and its tributaries often on both banks. The urban and industrial building areas appear as a continuum and the agricultural...

The late Carboniferous–early Permian represents a key period in the Phanerozoic history, given major global geodynamic and climate modifications. aim of this work is to better understand context characteristics sedimentation recorded continental environments eastern equatorial Pangea at time, through example Autun Basin (northeastern Massif Central, France). contains historical stratotype Autun...

A surface processes model incorporating large-scale fluvial processes, local hill-slope processes, and glacial erosion is used to investigate the effect of glaciation on the relief of a fast-growing, narrow orogen. The results of several simulations show that: glaciers concentrate erosion near peaks; fluvial erosion is reduced downstream of glaciers; glaciers with frozen bases can lead to an in...
