Description:
Abstract:
Io, the innermost of the Galilean satellites of Jupiter, is
one of the most
geologically active bodies in the Solar System. It is
dominated by volcanism and shows only minor surface
modification by tectonic processes or erosion. Impact
craters are not seen at the resolution of Voyager images,
indicating the relative youth of the surface (Smith and
others, 1979) and its rapid resurfacing by volcanic
eruptions (Johnson and others, 1979). As reviewed by Nash
and others (1986), most of our knowledge of Io is based on
data obtained by Voyagers 1 and 2, which encountered Io in
1979 and imaged about 35 percent of its surface (fig. 1).
Other information was obtained by Pioneer 10, which flew
past Jupiter in 1973, and from Earth-based observations and
theoretical considerations (Matson and others, 1981; Pearl
and Sinton, 1982; Goguen and Sinton, 1985; Lunine and
Stevenson, 1985). The general geology of Io was described
by Masursky and others (1979), Schaber (l980, l982) and
Nash and others (1986). Volcanic aspects have been
discussed by Carr and others (1979), Johnson and others
(1984, 1988), McEwen and Soderblom (1983), McEwen and
others (1985, 1989), and Carr (1986).
Purpose:
Supplemental_Information:
Four areas of Io have been mapped geologically at larger
scales: the Maasaw Paterzi area (lat 35° S. to 48° S., long
335° to 350°) at 1:1,000,000 scale (Moore, 1987); the Ra
Patera quadrangle (lat 5° N. to 20° S., long 290° to 340°)
at 1:2,000,000 scale (Greeley and others, 1988); the Ruwa
Patera quadrangle (lat 50° N. to 50° S., long 270° westward
to about long 40°) at 1:5,000,000 scale (Schaber and
others, 1989); and the Lerna (south polar) region (lat 45°
S. to 90° S.) at 1:5,000,000 scale (Whitford-Stark and
others, 1990). The present photogeologic mapping was
completed by compilation and synthesis of these maps and of
work in progress by C.A. Wood in the Colchis Regio
quadrangle and by extension into unmapped areas.

Attribute_Accuracy_Report:
All attributes created during the creation process were
verified by displaying the lines in both the database and
the spatial coverage, but no formal tests were performed.
Logical_Consistency_Report:
These data are believed to be logically consistent, though
no tests were performed. Line geometry is topologically clean.
