Geoff:
Moon Zoo user kodemunkey posts a lot of images of ‘black stuff’ on the forum and in November 2011 he posted a link to an NAC image in TLP Project - Black Stuff  but did not post the actual image.

The following overview image shows a fresh crater south of Hume crater on the farside. It has some lovely feathery textures and plenty of ‘black stuff’.


M141668809RC  Latitude: -5.5  Longitude: 90.7


Detail of the feathery ejecta to the north of the crater.


Ejecta to the south of the crater with black stuff.

This Wikispaces article has a good overview image of the unnamed crater showing its rays projecting into Hume crater.

This crater is also shown in another NAC image: M159358731LE

kodemunkey:

It would be great to know just what this "black stuff" is. I suspect what we have assembled is a collection of varied black/dark deposits some which is likely to be just darker rock/regolith but some of which might really be volcanic glass.

kodemunkey:
I've been thinking a little about that lately, and i've been wondering if it's possible to orient the position of the black stuff in Marius with one of the large nearby impacts (Aristarchus, Kepler, Copernicus) Having said that, i think the likely culprit for black stuff in the Schroter / Fauth / Somering and parts of Gambart region is the Copernicus impact, and equally the culprit for Marius's "Black Stuff" could be Marius itself.

Any idea when the new science lead reports in? we could do with their input  :)
