TLP Project - Black Stuff
« on: July 16, 2010, 06:48:23 pm »
Background: See this thread for background on this project: Moon Zoo Challenge

Location:Site: Montes Alpes, NW of Vallis Alpes (3.6W-1.4W, 48.9N-50.1N).

Images: M122218486RE, M122218486LE, M122232056LE, M122232056RE

Discovery: Anthony Cook and Moon Zoo Forum Moderator: Jules, on 6 Jul 2010

Description
: Dark slightly branching features, often on the shaded side of slopes. Boulders associated with these. Also appears as an exposed strata layer in a nearby rill rim.

Interest: Is this “dark stuff” an exposed dark material black volcanic glass, a deep branching crack with shadow, dark boulders, or a combination? Either way we need to find more of these and their geographical distribution. Could be worth monitoring these from orbit and at different sun angles to see if the darkness is related to shadow.

And a word of warning from Anthony:
"Some of the LROC candidate small crater pits with black markings on the floors could equally be some of this black volcanic glass that was suggested for the "Black Stuff" that we found."
So make sure you check out those too.

Section of LROC NAC image M122218486RC. The Sun is 37° above the local horizon so there should not be too much shadow except in deep areas. Illumination is from the bottom right.



A wider field view of a section of LROC NAC image M122232056RC. Sun angle also 37° above the local horizon.



Please post any "black stuff" you find in this thread. Don't forget a picture, the strip reference (LROC / NAC reference) and the approximate latitude and longitude.
Good luck! :)

I'd love to find this is man-made, but I'm assuming it's either the strangest boulder I've ever seen or some kind of blackened vent.  Any ideas?

I had a look around the wider area DJ and there are a lot of dark features which I think are boulder shadows. They are on the walls of Proclus Crater.

I've been exploring Aristarchus crater and found some dark patches which look interesting:



Strip: M109548636LE (from centre to south of Aristarchus crater)
Position: Bottom right.

All from M122218486RC. Spread over next few posts.
Interesting how this black stuff seems to follow a line or crater rim.
