Marine and subaerial erosion of volcanic ocean islands form coastal cliffs shore platforms, particularly during stable sea levels. Posterosional lava flows can spill over these fill the leading to progradation deltas. This work aims analyze this rocky coast setting at island scale assess constructional erosive degradational effects on one edifice. El Hierro Island, Canary Islands, exemplifies a...

Basement highs form one of many potential sediment source areas during the evolution continental rifts and rifted margins add to topographic complexity typical active rifts. Footwall basement acting as a area sedimentary systems in hangingwall major faults have been documented worldwide. However, back-tilted footwall dip slopes such received comparatively little attention. Here, we investigate ...

This paper introduces a methodology based on Python libraries and machine learning k-Nearest Neighbors (KNN) algorithms to create an interactive 3D HTML model (3D_Vertical_Sections_Faults_LRD.html) that combines 2D grain-size KNN-prediction vertical maps (vertical sections) from which syn-sedimentary faults other features in sedimentary porous media can be delineated. The visualized handled wit...

The geology of North-East Greenland (70–78°N) exposes unique evidence the basin development between Devonian collapse Caledonian Orogen and extrusion volcanics at Paleocene–Eocene transition during break-up Atlantic. Here we pay special attention to unconformities in stratigraphic record – do they represent periods stability non-deposition or subsidence accumulation rocks followed by episodes u...

In order to facilitate the search for new play concepts and exploration opportunities, a sequence stratigraphic synthesis of Cenomanian–Turonian interval Arabian Plate has been compiled. The is based on published datasets which have analysed within temporal framework constrained by biostratigraphy isotope stratigraphy. high resolution allows palaeogeography study area be mapped 3rd depositional...

The upper part of the Permian succession in Bowen Basin Queensland, NE Australia, was investigated to ascertain timeline and character environmental changes this high southern palaeolatitudinal setting leading up End-Permian Extinction (EPE). study focused on (in ascending order) Peawaddy Formation, Black Alley Shale, Bandanna laterally correlative units. In western Basin, base Formation (257 M...

Icy debris fans (IDFs) are extremely dynamic supraglacial landforms at the mouths of bedrock catchments between valley glaciers and icecaps. Recent studies quantified nature, pace, volume mass flow processes contributing ice sediment to IDFs by integrating field observations, drone time-lapse imagery, terrestrial laser scanning. New geophysical data presented herein characterize subsurface arch...

The Late Oligocene to Recent Canterbury Drifts were deposited in water depths between c. 400 and c. 1500 m by northward-flowing, cold, intermediate-depth water masses: Subantarctic Mode Water (SAMW), Antarctic Intermediate Water (AAIW) and their predecessor current flows. Drift accumulation started at c. 24 Ma, fed by terrigenous sediment derived from the newly rising Alpine Fault plate boundar...

Abstract. The frequency of debris flows is hypothesized to have increased in recent decades with enhanced rainstorm activity. Geological evidence test the relationship between climate and flow activity for prehistoric times scarce due incomplete sediment records, complex stratigraphy, insufficient age control, especially Alpine environments. In lacustrine archives, link onshore processes sedime...

Mass-transport deposits reveal something of the timing, source areas and depositional processes that contributed to the evolution of the New Jersey continental margin. Many of the mass-transport deposits rest upon prominent stratal surfaces and sequence boundaries permitting evaluation of the relationship between mass wasting and eustatic change. Five distinct mass-transport facies representati...
