|
|
Hello friends. Everything in my beloved Brazil is labeled as Minas Gerais, but I'm a precision locality addict. So, I attached some pictures of four samples I just received, with no label or doubtful ones.
The Beryl has a Schorl tourmaline fragment.
The Cleavelandite has Lepidolite/muscovite like columnar or acicular habit.
The brownish Microcline has a Schorl tourmaline fragment, a muscovite fragment and a botryoidal Hyalite opal cover at the back of the crystal.
Are there some Brazilian mineral locality masters here?
Thank you all.
Robson
