sounds abit geochemical, so your talking about layered autoCAD with isometric contouring of the required geochemical measurements.
in terms of showing all the elements on one image, thats more complicated and depends on what your trying to say with the map.
no point in having a map with too much on it.
so personally I'd treat it like OHP layering with RGB.
Any more than those and the colouring will get a bit 'fascinating'?.....
I would try asking a geoarch specialist though, as they will be more informed and up to date on this matter, in terms of current technological limitations / advances.
