Application of punched cards to geologic data concerning uranium deposits in sandstone

The punched card has been chosen for use in compiling the great mass of geologic data concerning uranium deposits in sandstone into permanent file. The most valuable uses of the punched-card file are as a multiple index to data and as a means of correlating different data. By using the punched card, uranium deposits in sandstone can also be compared to other metalliferous deposits in sandstone.Besides the geographic location of the deposit, about 120 different items can be punched on the sides of the card. In the center of the card more detailed data and a summary of the report are given. Although the card is designed for data on a single deposit or group of deposits, topical data on many studies such as chemistry, geobotanical prospecting, and geophysics can be summarized on the card.
