Introduction to this special section—Resolution

Abstract

Geophysicists since Karcher have been striving to improve resolution—to see thinner beds, to image smaller faults, and to detect lateral changes in lithology or rock property. The classic definition of resolution, provided by Bob Sheriff, is “The ability to separate two features which are very close together. The minimum separation of two bodies before their individual identities are lost on the resultant map or cross-section.”
