Abstract
Abstract Because of recent advances in microcomputer speed and memory, spreadsheet programs, such as Lotus 1-2-3, now can be used to solve highly technical exploration problems. One such application is interactive gravity modeling. The spreadsheet template GWIZ provides explorationists with a rapid and easy method for potential-field modeling. Using this template, many possible source solutions can be obtained for gravity profile data. This allows explorationists to apply their geologic experience to such problems in an efficient manner. Eighteen 2- and 2 1 2 - dimensional geometric models ranging from simple cylinders to complex polygonal prisms are supported. Parameter fitting can be performed manually or automatically. The advantage of using a spreadsheet, rather than conventional computer languages, for technical problems such as gravity modeling is that the spreadsheet program itself provides for screen graphics. input-output operations, and support for peripheral devices. This makes programming easier and user instructions simpler.
