3-D Structural Geology: A Practical Guide to Surface and Subsurface Map Interpretation

Manyimportant decisions,ranging from locating an oil prospect or a land-fill site to determining the location and sizeof an earthquake-producingfault,are based on geo­ logical maps. Because a map-scale structure is never completely sampled in three dimensions, geological maps and the cross sections derived from maps are always interpretations. The interpretation may be complicated by direct structural observati­ ons,likebedding attitudes,that are misleading because they represent a local st...
