Episodic plate separation and fracture infill on the surface of Europa
Article Abstract:
High resolution images obtained by the Galileo spacecraft present new information about wedge-band formation on Europa. It can be seen that a zone of dark, wedge-shaped bands extends WSW to around 40 degrees S, 250 degrees W in a prominent belt, 2,000 km by 600 km. The centre of the zone is around 15 degrees S, 215 degrees W, southwest of the anti-Jupiter point. It seems likely that plate fracturing and movement in response to regional surface stresses permitted material to rise passively to the surface to create the dark bands.

Io writes its history in hot metal
Article Abstract:
The deeper mantle of Io, a satellite of Jupiter, must be thoroughly mixed with the rocks at shallower depths, according to researchers who have analyzed infrared data indicating that the lava flows on Io are much hotter than had previously been estimated. This implies efficient recycling of the surface layers into the interior. There must be a connection between the degree of partial melting of the mantle, the range of depths over which it takes place and the rate at which the molten rock comes to the surface in new eruptions.

An integrated model of kimberlite ascent and eruption
Article Abstract:
A new model of kimberlite ascent and eruption is presented, which has emphasized the extremely unsteady nature of this process to resolve many of the seemingly contradictory characteristics of kimberlites and diatremes. The ascent and eruption of C[O.sub.2]-rich kimberlitic magma has accounted for many characteristics of kimberlites associated with diatremes.
