Description

TDB-1 was obtained from Tremblay Lake, Saskatchewan, Canada. This diabase rock is composed of a siliceous matrix containing numerous small masses, aggregates and discrete grains of titaniferous magnetite and ilmenite intimately associated with ferroan titanite. Several small grains of chalcopyrite and bornite are associated with the oxide aggregates. Some of the bornite grains are partly replaced by a thin layer of covelline. The siliceous matrix consists largely of plagioclase feldspar and pyroxene with minor amounts of mica and quartz.

TDB-1 was prepared and certified in cooperation with the Analytical Method Development Section of the Mineral Deposits Division of the Geological Survey of Canada (GSC).

The raw material was dried, comminuted and sieved to obtain a sub 74-micron (-200 mesh) product which was blended and bottled.

The homogeneity of the stock with respect to its gold, platinum and palladium contents was confirmed at GSC using bottles chosen according to a stratified random sampling scheme.

Certification

Thirty-three university, commercial, and government laboratories from Canada, United States, Europe, Australia, Africa, and Japan participated in an interlaboratory certification program. Up to 80 elements were analyzed by methods of each laboratory's choice. A statistical analysis of the data yielded recommended values for gold, platinum, palladium, and eight others, and provisional values were assigned for rhodium, iridium, and forty-seven others. An informational value for ruthenium and other elements is also given.
