The most popular theory is that the slopes form by gravity-driven, fluid-like movement of dry sand or fine-grained dust (analogous to an avalanche on Earth) exposing darker underlying material.
According to Conroy, who presented the data here at the fall meeting of the American Geophysical Union on 15 December, the amount of fine-grained dust in the lake sediment increased over the 20th century.
Do finer grained mutations that disrupt it affect circularization?
These laminae show a quasi-textile fabric and they can trap and conserve any dust and fine grained material.
Then, strong winds would loft that fine-grained, dehydrated dust and carry it far offshore, where it would nourish carbon dioxide sucking phytoplankton at the base of the ocean's food chain.
Two years later, the presence of an excess infrared emission close to Epsilon Eridani was announced, which indicated a disk of fine-grained cosmic dust was orbiting Epsilon Eridani.
These samples are of small amount and very fine grained, because the impact-sampling method failed to shoot projectiles for sample acquisition and only floating dust grains entered into the sample catcher (see Fig. 2).
However, the fine grained microstructure interspersed with coarser grained regions.
Each notebook allows very fine grained access control.
Clay minerals are fine grained and poorly crystalline.
