and a small amount of “rock flour”. Rock flour are very small rock particles that act
mechanically very much like the flour one cooks with in the kitchen. If a borehole

The Great Basin: A Natural Prehistory
The larger the glacier, the more of this material, called rock flour, is produced.
Streams issuing from the fronts of glaciers then carry it downward. If those
streams flow into lakes, the rock flour becomes incorporated into the sediments
that ...

Hydrothermal breccias occur as pipe-like to irregular bodies and are
characterized by angular to rounded fragments of one or more lithologies
cemented by variable amounts of rock flour and hydrothermal minerals. Gold

Sedimentology and Stratigraphy
The fine-grained rock flour formed by glacial abrasion is different in composition
to similar grade sediment produced by other mechanisms of weathering and
erosion. Rock flour consists of very small fragments of many different minerals.

The Quaternary Period in the United States
This led them to hypothesize that glacial rock flour dominated the clay-size
fraction of Owens Lake when it overflowed and they suggested that Na, Ti, Mn,
and Ba were excellent proxies of rock-flour abundance. In the following year,

During glaciations, rock flour in the lacustrine sediment increased, total organic
carbon decreased, and magnetic susceptibility peaked (Bischoff et al., 1997).
Therefore, oscillations in the chemical, mineralogical, and magnetic attributes of ...
