Title: Computer-Assisted Structural Analysis: ABSTRACT

Author(s): Joseph W. Fusso, Jr.

Article Type: Meeting abstract


The structural geologist's conceptual interpretations must be in accord with available data and in geometric balance. Traditionally, he has manually generated cross sections (two-dimensional) and maps (three-dimensional). From these models, iterative measurements of line lengths, areas, and volumes provide boundary conditions for a most logical solution. Projection and display from one domain to the other can involve tedious and error-prone work in the transformation of data elements.

Computer HELPWARE, defined as "the sum total of hardware, software, data management and, most important, peopleware," can assist the geologist in the search for a "most reasonable" interpretation.

Data management, with standardized definitions, is an essential element in automatic generation of maps from cross sections and vice versa. Three fundamental types should suffice; line, random, and grid formats each with linkage to a header record describing the subset attributes.

Input user-options include dynamically changing "L-Axis" projections of plunge and azimuth. The "L-Axis" interpretations may be determined from statistical curvature analysis techniques (SCAT) of dip-vector data.
