I don't have a lot of experience cataloging geologic maps, but when I have cataloged them, there have been times when the same question has occurred to me. I'd be interested in Chris Thiry's take on it. Isn't Gwen saying that there are sometimes contours, or isolines, on geologic maps that are showing something that might not be relief? In other words, are "structure contours" showing a relief of sorts, or are they showing the depth of a certain rock structure? And if the latter is the case, then I would think it would be correct, as Gwen suggests in her second alternative, to leave the relief code blank, and to put the note she suggests: Structure shown by contours [or isolines].

When a geologic map shows structure by contour lines, is that considered relief? Should it be coded as "Relf: a" and described in a note as - Relief shown by contours? Or, do the codes for relief only pertain to topographic and bathymetric relief? Perhaps the note should be "Structure shown by contours" and the relief code left blank. What do you think? ********************************** Gwen Curtis Geology Library and Map Collection University of Kentucky Libraries 410C King Library Addition Lexington, KY 40506-0039 Phone: (859) 257-1853 Fax: (859) 323-3225 Email: [log in to unmask] --
