@bewildered,
why must I provide a thin section when Im discussing yours?
Its obvious that the specimen youve included has several things going
1The circular white forms in photo A are air bubbles on the balsam or the clear mounting media. You can see in the second foto, WHICH is under cross nichols, that these "round areas go to extinction and have "shiny cruciform rays consistent with round air bubbles". The other dark and light shards (including the star shaped items) are leucocratic and melanocratic minerals consistent with the melt.
Id say that these were a series of pyroxene minerals that Id need to see go full cycle on the stage to define their extinction angle. The whites are probably feldpathoids like Bytownite or Anorthite. The temperature of this melt was probably quartz poor and therefore at a temp of over 1500 C. Depending on the grain size its either a diabase or a basaltic melt or even a serpentinite.
Your problem is that you dont have the necessary skills to determine what it is your actually looking at, so you are coming up with these wild conjectures.
Youre not being very convincing when you actually look at your stuff. Any kid who just finished micro petrolgy 201 could argue what youve seen better than you.
Trust me, its nothing alien, it merely a series of rocks with the crystal components therein.
