Analytical Sample Bundle Metadata


GSC –NC-2002-Committee Bay 56J, K, O Esker: De Beers Geoscience Laboratory, Johannesburg, South Africa IM grain counts

Type: lab data

Bundle Description

The 0.3-0.5 mm, 0.5-1.0 mm and 1.00-2.00 mm fractions of heavy mineral concentrates processed by DeBeers from Committee Bay esker samples (NTS56J, K, O) collected in 2001 were examined for 12 minerals/surface features, picked and counted. By De Beers Geoscience Laboratory, Johannesburg, South Africa.

These data are available in GSC Open File 4602.

Analytical Package Description

Laboratory: DeBeers Kimlab, Kimberly, South Africa

Name: De Beers Indicator Mineral Picking (more)

De Beers Indicator Mineral Picking. It is not clear if the samples are sieved by DeBeers prior to indicator mineral counts. Grains are picked for 9 different minerals and mineral characteristics indicative of kimberlites.

Analytical Suites:

1  De Beers Indicator Mineral Picking ( HMC 0.3-0.5 mm fraction )
2  De Beers Indicator Mineral Picking ( HMC 0.5-1.0 mm fraction )
3  De Beers Indicator Mineral Picking ( HMC 1.0-2.0 mm fraction )
