Notes
-----

Info files contain legend information of geological features.  Records in the
GEO2096_1.LEG info file are related to feature attributes using the CODE
item/field.  Values of the LEVEL item/field in the GEO2096_1.LVL info file
are related to the LEVEL items in the GEO2096_1.LEG info file.
The GEO2096_1.SYM info file list the symbols used for each of the CODE values

Abbreviations are always two letters starting with a capital.
 
A dash separates the special character abbreviation from the rest
of the unit reference letters (eg. Mz-g is (Mesozoic)g).
 
Multiple special characters in a unit reference will be strung
together as one (eg. (Mesozoic)(Archean)g -> MzAr-g
 
When a dash, comma or slash exists in a unit reference, it is
replaced with an underscore (eg. Mz-g, Mz-h -> Mz-g_Mz-h).
 
Age modifiers are a single case sensitive letter that appears before
the special character abbreviation (eg. (Late)(Mesozoic)g -> LMz-g
 
l - lower                    E - early
m - middle                   M - middle
u - upper                    L - late
