Abstract
⺠We produced the first complete, 1:15 M-scale global geologic map of Jupiter's moon Io. ⺠Io was mapped into 19 material units: plains (65.8%), lava flow fields (28.5%), mountains (3.2%), and patera floors (2.5%). ⺠Bright (presumably sulfur-rich) flow fields make up 30% more lava flow fields than dark (presumably silicate) flows (56.5% vs. 43.5%). ⺠We mapped 425 paterae, which cover only 2.5% of Io's surface, but correspond to 64% of all detected hot spots. ⺠The freshest bright and dark flows make up about 29% of all of Io's flow fields, suggesting active emplacement is occurring in less than a third of Io's visible lava fields.
