The general usage of the term is to include as pseudomorphs both petrifactions and molds, and also: (1) Any mineral change in which the outlines of the original mineral are preserved, whether this surface be a euhedral crystal form or the irregular bounding surface of an embedded grain or of an aggregate. (2) Any mineral change which has been accomplished without change of volume, as evidenced by the undistorted preservation of an original texture or structure, whether this be the equal volume replacement of a single crystal or of a rock mass on a geologic scale.
