area of the geochemistry and geology of ore deposits with emphasis on Phanerozoic orogenic gold. Much of his earlier career work was concentrated on the Tertiary orogenic gold deposits of southern Alaska. Results from this work were used to develop ore genesis models for giant gold deposits elsewhere in Alaska and in other parts of the North

    The gold that these rocks contained has been washed down into creeks to form alluvial placer gold deposits. Here the gold is further concentrated by the action of water. Because gold is heavier than most of the material moved by a creek or river it can become concentrated in hollows and trapped in the bed of the river. These are known as .
