F nomenclature (from the IAU and from unofficial sources)

Italics indicate farside features.

Note:
Because the peculiar class of surface formations informally named Fossae are very much unknown, each one of them should appear in the F list below, to get an overview of all of them, and also of those not included on the LTO charts.
(for the whole collection of LTO charts, see the LPI's overview of them in: http://www.lpi.usra.edu/resources/mapcatalog/LTO/).
