Fossil tabulate corals reveal outcrops of Paleozoic sandstones in the Atlantic Coastal Plain Province, Southeastern USA.

open access: yesPLoS ONE, 2019
The geologic history of the Southeastern United States of America is missing nearly 350-million-years of rocks, sediments, and fossils. This gap defines the Fall Line nonconformity where Upper Ordovician consolidated rocks are directly overlain by Upper ...

Slip inversion along inner fore-arc faults, eastern Tohoku, Japan [PDF]

open access: yes, 2017
The kinematics of deformation in the overriding plate of convergent margins may vary across timescales ranging from a single seismic cycle to many millions of years.

Sea Beam Survey of an Active Strike-Slip Fault: The San Clemente Fault in the California Continental Borderland [PDF]

open access: yes, 1989
The San Clemente fault, located in the California Continental Borderland, is an active, northwest trending, right-lateral, wrench fault. Sea Beam data are used to map the major tectonic landforms associated with active submarine faulting in detail ...

Effect of sedimentary heterogeneities in the sealing formation on predictive analysis of geological CO2 storage [PDF]

open access: yes, 2019
Numerical models of geologic carbon sequestration (GCS) in saline aquifers use multiphase fluid flow-characteristic curves (relative permeability and capillary pressure) to represent the interactions of the non-wetting CO2 and the wetting brine. Relative

Deep sequencing of subseafloor eukaryotic rRNA reveals active Fungi across marine subsurface provinces. [PDF]

open access: yesPLoS ONE, 2013
The deep marine subsurface is a vast habitat for microbial life where cells may live on geologic timescales. Because DNA in sediments may be preserved on long timescales, ribosomal RNA (rRNA) is suggested to be a proxy for the active fraction of a ...

Downhole logging as a paeoceanographic tool on ocean drilling program leg 138: Interface between high-resolution stratigraphy and regional syntheses [PDF]

open access: yes, 1992
On Ocean Drilling Program (ODP) Leg 138, standard shipboard procedures were modified to allow for the real-time monitoring of several laboratory core-scanning systems that provide centimeter-scale measurements of saturated bulk density, magnetic ...

Clastic Sediments in Caves – Imperfect Recorders of Processes in Karst

open access: yesActa Carsologica, 2007
Clastic sediments have played an important role in deciphering geologic history and processes since the inception of the discipline. Early studies of caves applied stratigraphic principles to karst deposits.

Seismic stratigraphy of the Ontong Java Plateau [PDF]

open access: yes, 1993
The Ontong Java Plateau, a large, deep-water carbonate plateau in the western equatorial Pacific, is an ideal location for studying responses of carbonate sedimentation to the effects of changing paleoceanographic conditions.
