Citation_Information: Originator: Publication_Date: Title: Publication_Information: Publication_Place: Publisher: Online_Linkage: 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.
