#xpl + accessory plate

But on the other hand!

I am BEGGING you to be the monazite. Please. I already labeled you as monazite. I have no idea what monazite looks like under thin sections. You're too goddamn similar to zircon. Why do you both have to be radioactive.

Rock thin section video! PPL to XPL to gypsum accessory plate. I'm fairly sure this is hornblende

Hornblende in Cross Polarized Light (XPL) with a Gypsum accessory plate inserted into the Microscope. The Gypsum plate alters the colors a bit, and is usually used with a Bertrand Lense (not engaged here) to determine a mineral's Uniaxial or Biaxial quality. Without that Gypsum plate, the background minerals would appear black and white. Maybe I'll upload a video of the transitions with each lense later. Bla bla bla science science science! Look at the pretty colors! Who else thinks I could make millions selling these as big posters/paintings? #Hornblende #Minerals #XPL #Bertrand #Microscope #Mineral #Mineralogy #Geology #EarthScience #Adventure #Adventurers #Explore #Exploration #Painting #Poster #Brilliant #Art #Millions #Rocks #Explorer (at California State University, Fullerton) https://www.instagram.com/p/Bq0SnMXF5O-/?utm_source=ig_tumblr_share&igshid=1vcpp11oxk06m

as much as i appreciate other people appreciating my thin section video, WHY does this have so many notes?

also for anyone curious: XPL > XPL + Gypsum accessory plate

woag, look at that feldspar's chemical zoning... now in MULTIPLE colors!
