Describes three microcomputer programs that allow geology students to deform two-dimensional images on a computer screen and then to measure changes in angular relationships. Two of the programs simulate pure and simple shear and the third simulates variations in shear strain that occur in shear zones. (ML)

Background information, data input, data analysis, and advantages of using this method with this software are discussed. A flowchart of the event-trapping program structure and a printout of the program are included. (CW)

Described is a simulation program designed to teach the geology of oil exploration in a game format. Discussed are information and tools provided, information management, data sets, and availability of the program. (CW)

Describes an open-ended computer simulation project that can be used to illustrate the growth of solid crystals in different forms at any level from high school physics to graduate physics. Discusses a simple computer program in BASIC language on an IBM personal computer. Gives examples of simulations. (CW)
