BASIC GEOLOGICAL INFORMATION IS PRESENTED REGARDING THE PROPERTIES OF VOLCANIC CINDERS, THE TYPES OF DEPOSITS AND THEIR COMMON LOCATIONS THROUGHOUT THE WORLD. THE USE OF THIS MATERIAL IN FOREIGN COUNTRIES IS REVIEWED INCLUDING NEW ZEALAND, GRENADA, AND GUATAMALA. CURRENT USAGE IN STATE FEDERAL ORGANIZATIONS ARE DISCUSSED TOGETHER WITH THEIR RESULTS AND RECOMMENDATIONS.
