[meteorite-list] Mineral ID PTS Please

[cdtucson at cox.net]

List,
I am still hoping to identify these minerals. I have added a plain light view. Please  excuse photo quality. 
Please note that third image shows a round mineral that with crossed polars disappears to black like glass. But looks like white sugar in sunlight.
Thank you.
