Multi-Disciplinary Analyses of Outcropping Late Cretaceous Clinoform Stratigraphy, Magallanes Basin, Chile
… fluids move from continents to deep-marine basins. Clinoforms, shelf-edge deltas, submarine canyons, and deep-water channels are central components of these systems, yet their stratigraphic architecture, sediment-routing behaviour, fluid trapping potential, and influence on organic matter …

Basin Evolution and Slope System Dynamics of the Cretaceous Magallanes Basin, Chilean Patagonia
Deep-marine basins linked to active continental margins by sloped ocean-floor profiles commonlyhost the final accumulation of sediment that was eroded and transported from the continents. Thedeep-marine sediment archives preserved in these settings commonly offer the most completerecord of sediment …

Sedimentology and Architecture of a Partially Contained Deposit, Cerro Solitario, Magallanes Basin, Chilean Patagonia
… the Upper Cretaceous Tres Pasos Formation of the Magallanes Basin. The evolution of partial containment at this outcrop is expressed as: 1) bypass in the proximal zone and flow stripping in the distal zone, 2) backstepping and blanketing of the outcrop, followed by 3) renewed bypass. The partially …

Multi-scale deep-marine stratigraphic expressions in the Cretaceous Magallanes Basin, Chile: Implications for depositional architecture and basin evolution
… Tres Pasos and Cerro Toro Formations in the Magallanes-Austral Basin. In the first research-chapter, Chapter 2, we analyze the transition between laterally offset and vertically stacked channels on a previously undocumented, seismic-scale outcrop of the Tres Pasos Formation. This change in …

Evaluating the impact of deep-water channel architecture on the probability of correct facies classification using 3D synthetic seismic data
… channels in the Tres Pasos Formation of the Magallanes Basin of southern Chile. The model includes outcrop- (bed and geobody) to seismic- (reservoir to basin) scale architecture. The primary objective is to quantify where and when channel architecture is accurately predicted by seismic facies …

Provenance of Eastern Magallanes Foreland Basin Sediments: Mineralogical and Geochemical Analyses Reveal Paleogene Tectonic Unroofing of the Fuegian andes
… Heavy mineral composition data from the eastern Magallanes basin of southernmost South America indicate that Campanian to middle Eocene sediments had a mafic/ophiolitic provenance which is interpreted as being derived from the Patagonian-Fuegian magmatic arc and the mafic floor of the preceding …
