This location contains the thickest development of
eluvium in the exploitation area, and a major objective was to establish in broad terms the volume of potential feed for the beneficiation plant.
In 1983 Gray and Forrest brought in heavy excavating equipment to explore the deeper beds of
eluvium, and more excellent material was uncovered, including a piece of rough that yielded an extraordinary 15.42-carat cut stone, far larger than the previously record-holder (7.5 carats) in the U.S.

Eluvium, the stage name of Portland-based ambient musician Matthew Cooper, will open the show at 9 p.m.
As [chi] values for the overburden (mainly deluvium and
eluvium) in the profile were often higher than that for bedrock outcrops, these values ([[chi].sub.del] and [[chi].sub.bed], respectively), were plotted separately in Fig.
The andradite was first noticed in the 1930's when attractive green single crystals and plates of crystals were collected from the weathered
eluvium. In 1937, the pegmatite was trenched for 13 meters for specimen-grade and facetting-grade andradite (McIver and Mihalik, 1975).
A landslide is a sudden movement of a mass of a surface bed of detrital minerals (
eluvium) and underlying rocks caused by some natural forces or by some human activity ("Geological Nomenclature", 1959).
