NATIVE GOLD, PLATINUM-GROUP MINERALS, AND NATIVE IRON IN MORAINE DEPOSITS OF CENTRAL RUSSIA (IVANOVO OBLAST)

Glacial sediments of the Khromtsovo deposit (Ivanovo oblast) are relat ed to the main Moskowian moraine. They are represented by gravel-pebbl e and gravel-sand material with beds of clay, sand, and boulders. The Khromtsovo mining plant develops moraine deposits and produces sand-gr avel mixtures. In the heavy fraction of artificial ore slimes of the t ailings dump, platinum-group minerals (PGM) and native iron occur; the se minerals are described. Their origin is discussed. The data obtaine d confirm the accompanying gold potential of sand-gravel deposits conf ined to moraine sediments. These sediments may serve as a new nontradi tional source of noble metal-gold and platinum-group elements (PGE).
