The above information on TLP also agrees with my other posts concerning the make-up of the Crater and the material contained in and around the crater
impact zone. 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
