Does distance e‐learning work? A comparison between distance and face‐to‐face learners using e‐learning materials [PDF]
, 2003 This study compares continual assessment data, intake numbers, retention numbers and final examination grades of a mixed cohort of face‐to‐face and distance learners against similar data from previous years where e‐learning materials were not used in ...

The 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.

The Contraction/Expansion History of Charon with implication for its Planetary Scale Tectonic Belt [PDF]
, 2016 The New Horizons mission to the Kuiper Belt has recently revealed intriguing features on the surface of Charon, including a network of chasmata, cutting across or around a series of high topography features, conjoining to form a belt. It is proposed that this tectonic belt is a consequence of contraction/expansion episodes in the moon's evolution ...

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

The 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 ...

Intermittent Granular Dynamics at a Seismogenic Plate Boundary [PDF]
Phys. Rev. Lett. 119, 138501 (2017), 2017 Earthquakes at seismogenic plate boundaries are a response to the differential motions of tectonic blocks embedded within a geometrically complex network of branching and coalescing faults. Elastic strain is accumulated at a slow strain rate of the order of $10^{-15}$ s$^{-1}$, and released intermittently at intervals $>100$ years, in the form of rapid

Global-scale control of extensional tectonics on CO2 earth degassing
Nature Communications, 2018 Earth degassing of CO2-rich fluids has been proven to contribute significantly to the global carbon budget. The presence of ubiquitous outgassing reveals some degree of permeability of the crust that often coincides with seismically active zones. In this

Active Tectonics in Southern Xinjiang, China: Analysis of Terrace Riser and Normal Fault Scarp Degradation Along the Hotan-Qira Fault System [PDF]
, 1993 The northern piedmont of the western Kunlun mountains (Xinjiang, China) is marked at its easternmost extremity, south of the Hotan-Qira oases, by a set of normal faults trending N50E for nearly 70 km.

The 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.
