Have you seen that alot of the craters shown have a different center?


Good catch Cygnific! means you are paying attention! If you're referring to the image here: s141.photobucket.com...

You are correct and a good catch, the centers don't match Aris.C. But this is because I mistakenly put the Crater Aristillus as being an Aristarchis Crater. ooppss...

The image I believe was from: www.lpod.org...
and their interface is alphabetical, I copied the Aristillus one by accident.

I guess i'll leave the image in the slideshow for now, and delete it next update when I add some more Aris.C images....

OK, this was the best I could do, I am not very good with imaging programs.



If you see only rocks or tricks of light and shadow don't worry, it happens to the best.

Here ArMaP take another look. Here is an enlargement of AS8-12-2209. Now does this look like a 'splash of mud'? Does this look like "painting the ground with a layer of the material ejected from the impact."

Does this look like a case of the 'direction of the light could make them (the long narrow rays) invisible because they are not in a position to reflect light, the only characteristic that differentiates them from the rest of the ground being their bigger albedo."
Yes, that's what they look to me, that is why I said what I said.

Remember it was composed primarily of Anorthosite, which is 90-100% Feldspar, which fluoresces is iridescent and generally are some weird arse rocks


Marvelous job of posting the accepted scientific versions

Too bad you messed it all up with this last bit of data...

Feldspar DOES NOT FLUORESCE ...EVER nor does it have PHOSPHORESCENCE

Fluorescence is an effect created by high energy light usually UV exciting particles in the rock causing it to glow, and depending on the content it can be VERY bright especially if Uraniun salts are present... (or Thorium which seems to be abundant on the moon) You could have made a better case for Thorium than Anorthosite. I suggest a visit to a tile store and LOOK at a piece of it... You will see just how dark it is and how little labradorescence it really has...

Phosphorescence means it actually emits light... but as has been stated here it needs to absorb sunlight and requires oxygen to produce the effect and it is limited by a very small pressure tolerance. Seems NASA thinks neither free oxygen or atmospheric pressure are in abundance on the moon...

The effect you are trying to give as cause for the blue glow of Aristarchus is labradorescence.... Though it sounds the same, its not.

Labradorite if you have a flat surface that is at a prcise angle you will get the effect when light strikes the surface and you view it from an exact angle. Anyone who has ever picked up a piece can testify to that fact. In fact the angle is so precise that its difficult to cut and polish and get great results...

In Anorthosite because of the cleavage of Feldspar, and the randomness of the pieces in the rock, you will find a percentage that will show this effect as you move it in your hand... but they are small flashes at best and not bright. The samples you posted are cut sections for MICROSCOPIC examination and are small

Moonstone {} also feldspar,,, exhibits a bluish "shiller" (the term commonly used for other varieties of feldspar... nice light blue

Sunstone is similar but usually brown or orange in color

But all of the effects from ANY FORM OF FELDSPAR are only reflected light and cannot account for the intensity of the glow reported, especially when the sun is behind the moon

As I said stick to engineering, leave rocks to the experts



o that kinda shoots down that whole theory...

Labradorite has what is c
