Primary results from mapping published in 2011 Icarus paper:
First complete global geologic map of Io, produced using Galileo and Voyager data
Hotspots (sites of volcanic activity) correlated with types of geologic features
Io has 19 geologic units in 5 classes: Plains (65.8%), Lava flow fields (28.5%), Mountains (3.2%), Patera floors (2.5%). Five types of superposed diffuse deposits cover ~18% of surface: Red (8.6%), White (6.9%), Yellow (2.1%), Black (0.6%), Green (~0.01%)
425 paterae cover 2.5% of surface, but correlate with 64% of hot spots => Dominance of silicate volcanism, in the form of lava lakes in volcanic craters
Only 2% of hot spots correlate with Bright Flows => Minimal active sulfur volcanism
