This paper treats of engineerisg geological description on distribution and relationship of geologic units. A concept of ``foreseeability'' is introduced. This is defined to the extent of predictive certainty around a point or a line of examination. From the viewpoint ``foreseeability'', necessity of which the pattern of distribution of geologic units is classified rises up. The classification proposed is as follows. A. Syngenetic structures A-1 Homogeneous body A-2 Layered body a. well continued b. poorly continued A-3 Heterogeneous body a. chaotic (block-in-matrix) b. heterogeneity of grain size or composition B. Postgenetic structures B-1 Deformation of geologic body a. fault b. folding B-2 Relationship among geologic units a. unconformity b. fluidal intrusion or injection The classification enables us to describe the controlling factors of the foreseeability and to evaluate the degree of foreseeability.
