Thirdly, increased accumulation instead of reworking had to be the main cause of the comparatively thick upper layer of five cores with very high inventories.Fourthly, assuming a variable accumulation rate and applying the CIC model and CRS model for these five cores, the weighted average CIC–MARs were in general more accurate than the CRS–MAR.Most sands form when rock materials are broken down by weathering and transported by a stream to their place of deposition.

A few rare sands are formed chemically from materials dissolved or suspended in sea water.

This photograph illustrates the size range of sand.

There is a scientific, industrial and commercial need to refine the geological framework for London and its surrounding area.

This paper reviews the geological setting of London as it is understood at present, and outlines the issues that current research is attempting to resolve.

The sand also contains fragments of mollusks, forams and other organisms. This image represents a 20 millimeter x 20 millimeter view.

The word "sand" is actually used for a "particle size" rather than for a "material." Sand is a loose, granular material with particles that range in size between 1/16 millimeter and 2 millimeters in diameter.

Finally, the Flux Balance model, which is not often used, gave MARs that were a factor 1.3 ± 0.2 ( = 25) too high.

The advantage of this model is that it is independent of the profile shape.

However construction work in London continues to reveal the presence of unexpected ground conditions.
