This report provides details on field activities in placer geology conducted by the Surficial Geology Unit of the British Columbia Geological Survey Branch. In 1989. studies of gold-hearing placer deposits at active mines were undertaken with the objective of identifying geological criteria useful for recognizing placer potential. This research was continued in I990 and a total of over 60 diffe...

Introduction: The particle size of surficial materials may provide important clues about the history of erosion, transport, and depositional processes that have acted to form the deposit. Particle size may also provide a valuable clue about the genesis of those deposits. On Mars, most of the surface is covered with at least a thin coating of various particulate materials that tend to obscure di...
