Abstract

The logical model of geologic structure is one type of mathematical model used for three dimensional geologic modeling. A 3-D geologic model is composed of a logical relation between geologic units and boundary surfaces (logical model of geologic structure) and gridded surfaces (DEM). If the logical model and gridded surfaces are given, we can define a geologic function that assigns a geologic unit to every point in the 3-D space Ω. At present, 3-D geologic models are able to be constructed and visualized, and several software and web systems for 3-D geologic modeling have been developed based on the geologic function. However, not all geological phenomena are currently able to be expressed, and some problems remain. For practical use, it is necessary to formulate more geologic principles and develop algorithms for the purpose of modeling.
