A perspective on the emergence of modern structural geology: Celebrating the feedbacks between historical-based and process-based approaches [PDF]

open access: yes, 2013
Structural geology has emerged as an integrative, synthetic science in the past 50 years, focused on deciphering the history preserved in the rock record and determining the processes of rock deformation.

Dissipated Energy and Pore Pressure Generation Patterns in Sands and Non-Plastic Silts Subjected to Cyclic Loadings

open access: yesGeotechnics
The factors that influence dissipated energy and pore pressure generation patterns with respect to the cycle ratio and dissipated energy ratio were analyzed using the results of cyclic triaxial and cyclic direct simple shear tests.

Constraining the timing and processes of pediment formation and dissection: implications for long-term evolution in the Western Cape, South Africa [PDF]

open access: yesEarth Surface Dynamics
Pediment surfaces are a widespread feature of the southern African landscape and have long been regarded as ancient landforms. Cosmogenic nuclide data from four pediment surfaces in the Gouritz catchment, Western Cape, South Africa, are reported ...

Generation of normal and adakite-like calc-alkaline magmas in a non-subductional environment: An Sr-O-H isotopic study of the Apuseni Mountains neogene magmatic province, Romania [PDF]

open access: yes, 2007
Neogene magmatism in the Apuseni Mountains of Romania was active between 15 and 7 Ma, with an isolated final eruption at 1.6 Ma. Several groups of magmatic rocks can be distinguished in the province on the basis of ages, trace elements and isotopic ...

Flow through and Volume Change Behavior of a Compacted Expansive Soil Amended with Natural Biopolymers

open access: yesGeotechnics
Natural biopolymers offer a sustainable alternative for improving soil behavior due to their inert nature, small dosage requirement, and applicability under ambient temperatures.

Concurrent modes of climate variability linked to spatially compounding wind and precipitation extremes in the Northern Hemisphere [PDF]

open access: yesEarth System Dynamics
Compound wind and precipitation (CWP) extremes often cause severe impacts on human society and ecosystems, such as damage to crops and infrastructure.

Influences on continental margin development: a case study from the Santos Basin, South-eastern Brazil [PDF]

open access: yes, 2013
South Atlantic margins display significant variation in structural style along their length. An understanding of factors that influence this variation in structural style is a key component in any understanding of the evolution of the South Atlantic. The

Structural relaxation in silicate melts and non-Newtonian melt rheology in geologic processes [PDF]

open access: yes, 1989
The timescale of structural relaxation in a silicate melt defines the transition from liquid (relaxed) to glassy (unrelaxed) behavior. Structural relaxation in silicate melts can be described by a relaxation time, , consistent with the observation that ...

Spatiotemporal denudation rates of the Swabian Alb escarpment (southwestern Germany) dominated by anthropogenic impact, lithology, and base-level lowering [PDF]

open access: yesEarth Surface Dynamics
Surface denudation rates, a composite of physical erosion and chemical weathering, are governed by the tectonic, lithologic, climatic, and biotic conditions of a landscape and anthropogenic disturbances.

Structural evolution of the Tenggol Arch and its implication for basement fracture patterns in the Malay Basin, Malaysia [PDF]

open access: yes, 2008
The aim of this thesis is to evaluate the hydrocarbon potential of the Tenggol Arch, a basement high that forms part of the western margin of the Malay Basin, offshore peninsular Malaysia. Fractured crystalline basement rocks in this area have previously
