Rock Analysis Storage System (RASS), Saudi Arabia; an introduction to the system and sample submittal manual, 1978
The U.S. Geological Survey Saudi Arabian Mission has the responsibility for implementing a computer-based file known as the Rock Analysis Storage System (RASS), which is principally a geochemical data bank or library. Geologic parameters are necessarily provided for, but are far from comprehensive; nevertheless, nine years of operation in the U.S. has demonstrated that the simplicity of the version described herein has helped induce many scientists frequently to use the system. Their extensive participation has proved the system to be adequate for the reduction of data and consequent publication of scientific papers.
