Facies variability in deep water channel-to-lobe transition zone : Jurassic Los Molles Formation, Neuquen Basin, Argentina
(2014-05)This study focuses on the facies changes from the lower slope to toe-of-slope to basin floor over a 10 km outcrop belt, in down-dip and oblique-strike directions to the basin margin. The Jurassic Los Molles Formation in ... -
A fluid inclusion and cathodoluminescence approach to reconstruct fracture growth in the Triassic-Jurassic La Boca Formation, Northeastern Mexico
(2011-12)Opening-mode fracture shapes are typically the result of brittle deformation and proportional growth in fracture height, length, and width. Based on the typical fracture shape, it is assumed that fracture tips are free to ... -
New records of early Jurassic gladius-bearing coleoids (Prototeuthidina and Loligosepiina) from Alberta, Canada
(2016-05-06)The Ya Ha Tinda Lagerstätte from Alberta, Canada, preserves organic-rich black shales that capture the carbon isotope excursion (CIE) characteristic of the Toarcian Oceanic Anoxic Event (183 Ma). Excavations at Ya Ha Tinda ... -
The role of bacteria in the deposition and early diagenesis of the Posidonienschiefer, a Jurassic oil shale in southern Germany
(1988-05)The Jurassic (Toarcian) Posidonienschiefer of southern Germany is famous for its well preserved vertebrate fossils and its high organic content. The majority of the Posidonienschiefer (10 meters thick in the study area) ... -
Sequence stratigraphic analysis of marginal marine sabkha facies : Entrada Sandstone, Four Corners region
(2010-08)The Middle Jurassic Entrada Sandstone of the Four Corners region, USA, is composed predominantly of very fine-grained, red, silty sandstone with poorly defined sedimentary structures. The origin of this facies is enigmatic, ...
