The use of vertical grain size progressions in establishing the depositional environment of ancient sand bodies
(1982)
This study demonstrates the validity of using vertical grain size progressions as an environmental indicator for ancient clastic sequences. Previous methods of grain size analysis are shown to be generally unreliable for ...
Melville Island's salt-based fold belt (Arctic Canada)
(1991)
Melville Island lies astride the Cambrian through Devonian Arctic Platform, correlative rocks of the Franklinian Mobile Belt and, unconformable post-Devonian cover of the Sverdrup Basin. Seismic profiles and a revised ...
A structural study of the Hukou and Hsinchu areas Northwestern Taiwan
(1985)
Northwestern Taiwan, which includes the Kuanyin, Hukou and Hsinchu areas, was initially a part of the continental shelf of the mainland China coast. The Neogene sediments were deposited m gently east-dipping basement in a ...
Tectonic evolution of the Gibraltar Arc
(1994)
The Betic Cordillera of Spain and the Moroccan Rif constitute the northern and southern branches of the Gibraltar Arc, which is the western limit of the Alpine-Mediterranean system. The frontal units (i.e. the Guadalquivir ...
Separating tectonic, eustatic, and episodic depositional processes in the stratigraphic record of the basins of southeastern and northwestern Australia (Cretaceous Period)
(1995)
Four dynamic processes interact to create the stratigraphic record in a basin: climate, sediment supply, eustasy, and subsidence. To identify the contribution of each of these processes, techniques that can uniquely separate ...
Triassic-Jurassic extensional systems and their Neogene reactivation in northern Morocco (the Rides Prerifaines and Guercif Basin)
(1996)
The "Rides Prerifaines" of northern Morocco represent an unusual type of inversion that inverts only the sedimentary fill of a complex Triassic-lower Jurassic half-graben system, without significantly involving the underlying ...
Small Venusian coronae
(1993)
The common defining factor of coronae is a distinct annulus of tectonic origin. Current coronae classification is based on an intensive study of coronae primarily with maximum widths in excess of 100 km. Topographically ...
The evolution of the Brazos and Colorado fluvial/deltaic systems during the Late Quarternary: An integrated study, offshore Texas
(1995)
The evolution of the Brazos and Colorado fluvial/deltaic systems over the last 190,000 years is examined. The data set includes high-resolution seismic data, lithostratigraphic data from offshore platform borings, cores ...
Eastern Venezuela Basin: Sequence stratigraphy and structural evolution
(1996)
A regional study has been carried out within the Eastern Venezuela Basin and its offshore continuation to the Orinoco Delta and the Barbados Accretionary Complex. The Eastern Venezuela Basin and its offshore continuation ...
Mesozoic Geology of the Sand Springs Range, West-Central Nevada
(1995)
Mesozoic structures and rock types mapped at a scale of 1:80000 in the Sand Springs Range (SSR), west-central Nevada, differ from those in adjacent allochthons. SSR structures and rock types contrast with those in better-known ...
