AbstractAmultiple hierarchical system of rock classification is introduced to permit widely applicable thematic querying of bedrock geological databases. The classification is based on three main rock character-istics: composition, texture, and fabric. These characteristics permit queries that would yield results useful across scientific disciplines that rely on rock properties (e.g. agriculture, forestry, fishery). In addition, rock names in the classification are linked to the common geological genetic criteria: igneous, sedimentary, and metamorphic. These genetic assignments would yield results useful for traditional geological thinking. The linkage between a rock classification built on rock properties and fundamental rock genesis appears to pro-vide the most versatility for computer-based rock database systems. The scheme is extensible and can easily adapt to the evolution of genetic concepts.
