Quartz forming conditions in secant veins in granodiorites of the Andean intrusive complex of the Barchans Islands (Argentine Islands, West Antarctic)

Доповiдi Нацiональної академiї наук України
It is established that the growth of quartz in veins in granodiorites of the Andean intrusive complex (the Barchans Islands, West Antarctic) happened in rock crystal-bearing veins of steep falling, in which the temperature difference necessary for the ...

The dynamics of barchans and dome dunes Namib Desert, Namibia

, 2009
Dome and barchan sand dunes are common along the west coast of the Namib Desert. In an area near Walvis Bay, central Namibia, three dome dunes and three barchans were monitored by three-dimensional topographic survey over a fivemonth period in order to ...

Size-dependent asymmetry of barchans indicates dune growth controlled by basal area or bulk volume

We introduce a novel analytical model of the growth of barchan dunes in terms of their two flanks, from which we derive expressions for the size-dependence of the bilateral asymmetry of these bedforms in three cases where different mechanisms dominate ...

The Combined Effect of Sediment Availability and Wind Regime on the Morphology of Aeolian Sand Dunes

, 2018
International audienceAeolian-driven sand dune orientation is a key parameter that determines dune morphology. Although wind regime, surface condition, and sediment availability all control sand dune formation, researchers have mostly put emphasis on the
