TLP Project - Ina-like Features
« on: July 16, 2010, 06:51:57 pm »
Background: See this thread for background on this project: Moon Zoo Challenge

Location: Mare Vaporum (5.3E, 18.6N).

Images: M113921307RE, M106841323RE

Discovery: From the Apollo era

Description: A semi-circular depression filled with an irregular rough floor, peppered with
blob-like lava extrusions, often surrounded by a shallow moat.

Interest: For many years after the Apollo era, this formation proved a mystery. One idea was
that based upon the apparent lack of craterlets on the floor, it was formed geologically
recently, perhaps due to explosive outgassing where the top soil had been blown away
leaving underlying bedrock. However LROC scientists have since shown that craters are
present in the irregular floor area, so it is no longer deemed to be geologically young.
Nevertheless it would be a good idea to keep a look out for similar features elsewhere,
just in case some were caused by outgassing.

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

That's a good one Tom - Aristarchus region. Not a distinct separate feature like Ina but appears to have the correct mix of terrain.
This is the strip if anyone wants a detailed hunt:

I've been exploring around Proclus crater, which is an interesting area, and found something that looks a bit like a "melt" but also with lots of boulders around.


The estimated coordinates are:
Latitude: 16.3
Longitude: 46.5
from strip M113649971

This is Ina (You can tell from the coordinates.)
We are looking for Ina like features elsewhere on the Moon. :)

Now this is interesting!
I'll go have a poke around. :)

EDIT: Seems to be a mixture of excavated rock and impact melt on the walls of Aristarchus. Really interesting area but sadly not Ina-like. I was quite hopeful there! Oh well....

Nice find Els!

Looks like it's near Aristarchus crater.
