A total of four muddy–fine sand deposits attached to the undersides cobles and boulders three Claudiconcha japonica fossils were collected determine formation age conglomeratic beachrock developing at Sasebo, Nagasaki prefecture. The geology surveyed coast consists non-limestone rocks. Radiocarbon dating using Accelerator Mass Spectrometry (AMS14C dating) for samples was conducted beachrock. It...

We explore the effect of magnetorotational turbulence on the dynamics and concentrations of boulders in local box simulations of a sub-Keplerian protoplanetary disc. The solids are treated as particles each with an independent space coordinate and velocity. We find that the turbulence has two effects on the solids. 1) Meter and decameter bodies are strongly concentrated, locally up to a factor ...

Abstract The extent of glaciers in the western French Alps foreland during last glacial maximum (LGM, 26.5–19 ka) has not yet been determined, so understanding paleogeography LGM remains an open question. This study focuses on chronology piedmont using 10 Be surface exposure ages nine boulders and 12 erratic boulders. Results indicate glacier advance between ca. 24 21 ka. During late LGM, a sma...

[1] Glacial boulders and soils on moraines are often dated to quantify the timing of glaciations and/or rates of chemical weathering in moraine chronosequences. A common assumption is that moraine crest erosion and soil mixing are unimportant. However, several studies suggest moraine denudation may be substantial. We evaluate the magnitude of moraine denudation and soil mixing in the Pinedale (...

Here we report a controllable method based on electrodeposition to fabricate Ag nanodendrites (NDs) on a microwell patterned electrode. The microwell patterns on the ITO electrode are fabricated via the microcontact printing technique. By varying the microwell size and electrodeposition time, the morphology of metal deposits on the microwell patterned ITO electrode can be tuned from boulders to...

On timescales of days to months, the motion of cometary dust is mainly affected by solar radiation pressure, which determines dust dynamics according to the particle-scattering crosssection. Within this scenario, the motion of the dust creates structures referred to as dust tails. Tail photometry, depending on the dust cross-section, allows us to infer from model runs the best available outputs...
