This caused a residual alluvial deposit, which resulted in relatively deep and fertile soils.

A few weeks ago fresh alluvial deposits were found nearby.

Greasy wool was used to trap gold flakes washing past from the alluvial deposits.

This involved the removal of 230,000 tonnes of rock and alluvial deposits.

These large sand dunes are the modern ancestor of alluvial deposits that became shaped and dominated by an exchange of aeolian and fluvial processes.

Alluvial gold was mined in the area after its discovery in 1862.

The river remains, to a lesser degree, a source of alluvial gold and diamonds.

This was followed by exploitation of alluvial gold usually in creeks and rivers.

Alluvial gold was discovered in 1854 and 5,000 miners came to the area creating a gold rush.

Alluvial gold was later found in 1900 and a townsite was established to house the miners.

Wild plants living in the rich alluvial soil of the two rivers could be supplemented with fish, shellfish, and waterfowl.

Due to lack of suitable stone in the alluvial soil locally available, the temple makers had to resort to other materials instead of stone.

These are alluvial soil, which by nature are easily eroded and deemed unsuitable for development.

Alpine marmots prefer alpine meadows and high-altitude pastures and colonies, where they live in deep burrow systems situated in alluvial soil or rocky areas.

The river also provides the different alluvial soil types found around the region, which included granite, red clay, loam and gravel.
