Described is a mineral identification program which uses a shell system for creating expert systems of a classification nature. Discusses identification of minerals in hand specimens, thin sections, and polished sections of rocks. (Author/CW)

Advocates a computer-controlled x-ray diffractometer as an inexpensive analytical tool that is easy to use and applicable to a wide range of geological problems. Both qualitative and quantitative experiments are possible. Exercises can easily be customized to local geology. Ideal for small departments with limited resources for providing hands-on…

Discusses the use of interactive computer-assisted lab exercises that combine text, graphics, and simple animation. Students use these self-paced applications to test their level of comprehension, identify their misconceptions, and seek explanatory information. Benefits include consistency in teaching and evaluation, and the ability to link with…

Described is a software package, "Trapeze," within which a routine called LinDis can be used. Discussed are teaching methods, the linear discriminant model and equations, the LinDis worksheet, and an example. The set up for this routine is included. (CW)

Presented is a description of a BASIC program to be used on an IBM microcomputer for calculating and plotting synthetic seismic-reflection traces for multilayered earth models. Discusses finding raypaths for given source-receiver offsets using the "shooting method" and calculating the corresponding travel times. (Author/CW)

Describes how interactive programs for scientific modeling may be created by using spreadsheet software such as LOTUS 1-2-3. Lists the advantages of using this method. Discusses fractional distillation, batch partial melting, and combination models as examples. (CW)

Spreadsheets are well suited to many geochemical calculations, especially those that are highly repetitive. Some of the kinds of problems that can be conveniently solved with spreadsheets include elemental abundance calculations, equilibrium abundances in nuclear decay chains, and isochron calculations. (Author/PR)

Discussed are field analyses of data involving paleocurrent directions using a goniometer and special programs for a pocket computer. States that on-site evaluation can provide immediate realization and verification of anomalous results. Includes computer programs and directions for building a goniometer. (CW)

Discussed is a program created to serve as an instructional tool for teaching basin analysis. Described is the use of the program for interpreting plots resulting from backstripping methods. Included in the discussion are implementation, applications and availability of the "Subside!" program. (CW)

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)

This article presents a vector-analysis approach to the classical three-point problem in hydrogeology. Problem sets involving strike and dip, and ground water flow including computer programs (in BASIC) for their solution are given. (CW)

Describes a microcomputer program that simulates the pattern of evolution and produces clade diagrams and summary statistics. Allows users to vary the odds affecting the fate of a species. (TW)

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)

Described is a computer telecommunications network, MicroNet, which is used to deliver necessary coursework and support for teachers and a variety of enrichment activities for their students via distance learning. Discussed are computer telecommunications courses and middle-grade and high school use of the MicroNet system. (Author/CW)
