Charles Darwin y las glaciaciones más antiguas de Patagonia: los bloques erráticos del alto valle del Río Santa Cruz [PDF]

open access: yes, 2009
Although the depositational environment assigned by Darwin to the large erratic blocks and gravels in the Río Santa Cruz valley has been reinterpreted, his geomorphological and stratigraphic observations are still in force.

Gentle Slopes and Fluvial Terraces around Mt. Shokanbetsudake, Hokkaido

open access: yesAnnals of The Tohoku Geographycal Asocciation, 1987
This paper discusses the paleoenvironment of eastern slopes of Mt. Shokanbetsudake, Hokkaido, on the basis of evidences of gentle slopes and fluvial terraces.The fluvial terraces are classified into five surfaces (terrace I to V in descending order) and the gentle slopes into two surfaces (gentle slope I and II). In most case, gentle slope I and gentle

Refining the timing of Middle Pleistocene (MIS 12 to MIS 6) ice advances into northern central Europe: sedimentological analysis and single‐grain luminescence dating of glaciotectonic complexes and tunnel‐valley fills

open access: yesBoreas, EarlyView.
We summarize the current state of knowledge on the age of the Middle Pleistocene ice advances into northern central Europe and provide 25 new single‐grain feldspar luminescence ages of Elsterian and Saalian glacigenic sediments to constrain the age of the ice advances and their tentative correlation with marine isotope stages/substages.

Application and evaluation of sediment fingerprinting techniques in the Manawatu River catchment, New Zealand : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Geography at Massey University, Palmerston North, New Zealand [PDF]

open access: yes, 2016
Suspended sediment is an important component of the fluvial environment, contributing not only to the physical form, but also the chemical and ecological character of river channels and adjacent floodplains.

X‐ray computed tomography study of terrestrial analog cores in preparation for Mars sample return

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Mars Sample Return (MSR) is expected to transform planetary science by providing unprecedented access to pristine Martian material. Initial characterization in the sample receiving facility (SRF) will rely on nondestructive techniques such as X‐ray computed tomography (XCT) to document the condition, distribution, and internal features of ...

Fluvial stratigraphy and palaeoenvironments in the Pasinler Basin, eastern Turkey [PDF]

open access: yes, 2005
Valley floor sediments from the Pasinler Basin, eastern Turkey, provide evidence for Pleistocene and Holocene floodplain conditions. Three terrace surfaces are present.

Paleoseismic and Slip-Rate Observations along the Honey Lake Fault Zone, Northeastern California, USA [PDF]

open access: yes, 2008
The Honey Lake fault is a major strike-slip fault in northeastern California that accommodates northwest-directed right-lateral shear in the northern Walker Lane.

Bio‐mediated cementation of supratidal beach sediments associated with groundwater springs

open access: yesSedimentology, EarlyView.
ABSTRACT The formation of beachrock, sensu stricto, via carbonate precipitation in the intertidal zone is widespread throughout the tropics and subtropics. While cementation of supratidal beach sediments has also been noted in several locations, it has received much less attention.

Luminescence Dating of Beach Dunes and Fluvial Sediments, Nayarit, Mexico [PDF]

open access: yes, 2018
The Pacific coast of the state of Nayarit, Mexico, is dominated by extensive sand dune systems and lagoons. 16 samples from three transects through dunes near the town of Santa Cruz were collected to establish ages of the beach dune ridges and establish ...
