Abstract
Use of Computers by Geologists: Abstract
Abstract
Computers now are being used by geologists to aid in the exploration and exploitation of natural resources. Many statistical techniques easily can be utilized with readily available third-generation machines. Trend analysis, correlation methods, and classification procedures are used routinely to help in solving many geologic problems. As computer programs and quality data become available undoubtedly these tools will be used more and additional ones will be developed. It should be obvious that the use of computers is not expedient in all instances, but is especially applicable for manipulations which are performed many times or to unravel extremely complex situations. The potential of the computer is not yet realized, but involvement with them is creating a "new way of life" and certainly effecting change. This change is being felt in science as well as social and economic aspects of our everyday life.
Trend Analysis | Correlation Methods | Classification Procedures |
---|---|---|
2D, 3D, and 4D trend analysis | auto- and cross-correlation | matching coefficients (including similarity, correlation, distance, and cosine-theta) |
harmonic analysis (includes time series, Fourier and power-spectrum analysis) | auto- and cross-association | PCA (principal component analysis), factor analysis, and cladistic methods |
