Records in the GEO4930_1.LEG info file are related to feature attributes using the CODE item/field. Values of the LEVEL item/field in the GEO4930_1.LVL info file are related to the LEVEL items in the GEO4930_1.LEG info file. The GEO4930_1.SYM info file list the symbols used for each of the CODE values listed in the GEO4930_1.LEG info file. Abbreviations for GSC Special Characters ---------------------------------------- These abbreviations occur in the values of the item CODE for geological units as well as in the description of geological units in the geological legend info file. Cn - Cenozoic Cb - Carboniferous Qt - Quaternary Dv - Devonian Rc - Recent Sl - Silurian Ps - Pleistocene Od - Ordovician Te - Tertiary Cm - Cambrian Pi - Pliocene Pt - Proterozoic Mi - Miocene Hd - Hadrynian Og - Oligocene Hl - Helikian Ec - Eocene Nh - Neohelikian Pc - Paleocene Ph - Paleohelikian Ng - Neogene Ap - Aphebian Pg - Paleogene Ar - Archean Mz - Mesozoic Ho - Holocene Ct - Cretaceous Na - Neoarchean Jr - Jurassic Pa - Paleoarchean Tr - Triassic Ma - Mesoarchean Pz - Paleozoic Ea - Eoarchean Pr - Permian Np - Neoproterozoic Pn - Pennsylvanian Pp - Paleoproterozoic Ms - Mississippian Mp - Mesoproterozoic 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
