Ganymede surface details

Many surface details are visible in this image of Jupiters largest moon, Ganymede.
To the right is the same image shown with labels of the features I have been able to identify.
In the upper right is Osiris, a relatively recent impact crater surrounded by a large area of bright ejected material.
Next to Osiris is the dark Marius Regio just coming into view, and further south is the bright Uruk Sulcur strething across the disc. This is a large system of rilles and canyons, separating Marius Regio from the larger Galileo Regio in the south.
Near the south pole is a lighter area identified as Zu Fossae, and to the left is yet another dark area, Perinne Regio, on the left limb.
