RESEARCH FOCUS: The future of the sequence stratigraphy paradigm: Dealing with a variable third dimension

open access: yes, 2016
Sequence stratigraphy is a method and a model, and perhaps actually a paradigm, to make observations, interpretations, and predictions about strata, with important applications, from the search for hydrocarbons to an understanding of the geological ...

Towards a sequence stratigraphic solution set for autogenic processes and allogenic controls: Upper Cretaceous strata, Book Cliffs, Utah, USA [PDF]

open access: yes, 2016
Upper Cretaceous strata exposed in the Book Cliffs of east–central Utah are widely used as an archetype for the sequence stratigraphy of marginal-marine and shallow-marine deposits.

Mapping Ancient Structures and Demonstrating Integrated Archaeological Geophysics at Huacas de Moche, Peru

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT At the Huacas de Moche (HdM), one of the most prominent archaeological sites in Trujillo, Peru, the needs of an expanding modern community are in direct conflict with the desire to preserve the wealth of archaeological information. The undetermined extent of the HdM site introduces disputes in land usage where potential archaeological features

The first stratigraphic column in South Africa, from Hondius (1652), and its modern correlatives

open access: yesSouth African Journal of Science, 2012
In 1647 the Dutch ship Haarlem, en route from Batavia to the Netherlands Republic, was wrecked in Table Bay. The survivors were encamped over the next year before they were rescued in a fort they constructed called Sandenburgh.

Facies variations in gravelly cyclic steps deposited from turbidity currents: Miocene fan delta front deposits compared with a modern active fan delta, central Japan

open access: yesThe Depositional Record, EarlyView.
This paper provides a new facies model of gravelly cyclic steps that includes a facies model of lee side and variations deposited from hyperpycnal and surge‐type high‐density turbidity currents. Abstract Gravelly cyclic steps formed by turbidity currents have recently been widely recognised in the geological record.

SEQUENCE STRATIGRAPHY AND PALEONTOLOGY OF THE UPPER MIOCENE PISCO FORMATION ALONG THE WESTERN SIDE OF THE LOWER ICA VALLEY (ICA DESERT, PERU)

open access: yes, 2017
The sequence stratigraphic framework and a summary of the fossil fauna of the upper Miocene portion of the Pisco Formation exposed along the western side of the Ica River (southern Peru) is presented through a new geological map encompassing an area of ...

Seismic stratigraphy and history of deep circulation and sediment drift development in Baffin Bay and the Labrador Sea [PDF]

open access: yes, 1989
Drilling results and seismic-reflection records at and across Ocean Drilling Program (ODP) Sites 645 (western Baffin Bay), 646, and 647 (Labrador Sea) provide important constraints on the history of deep-water circulation and sedimentation in response to

Testing the fidelity of zircon as a provenance indicator in fluvial‐fan successions: An example from the Palaeogene Colton Formation, Central Utah, USA

open access: yesThe Depositional Record, EarlyView.
This study integrates and expands the U–Pb detrital zircon dataset from the Colton fluvial system to highlight spatial variations in provenance signals within the early Palaeogene infill of the south‐western Uinta Basin, in Utah. The provenance data sheds light on the origin of clastic sediment and on the relationship with potential palaeodrainage ...

Hydrologically sensitive carbonates: Tectonic and groundwater controls on synrift sedimentation in the Late Jurassic–Early Cretaceous of the western Cameros Basin, Northern Spain

open access: yesThe Depositional Record, EarlyView.
Late Jurassic extension, footwall uplift, erosion and karstification of marine Jurassic carbonates in the western Cameros Basin (Spain) resulted in the deposition of ?Upper Kimmeridgian‐Tithonian syntectonic alluvial fan deposits and a series of ?Tithonian to Berriasian distal alluvial marls, palustrine, lacustrine and finally lagoonal carbonates.

Facies analysis, sequence stratigraphy and chemostratigraphy of the Sete Lagoas Formation (Bambui Group), northern Minas Gerais State, Brazil: evidence of a cap carbonate deposited on the Januária basement high

open access: yesBrazilian Journal of Geology
: Sedimentary rocks of the Sete Lagoas Formation, exposed in the left margin of the São Francisco river (Minas Gerais State, Brazil), were deposited on the Januária-Itacarambi basement high.
