Lepidolite.... I only know it because it contains LITHIUM. And it's the only one I can get from those crystal shops ran by those..... kinda gurls who wear tied died stuff and have incense burning constantly and read their horoscopes. WOULD LIKE TO get a nice spodumene (pegmatite) because that's the MAIN lithium mineral mined in Australia. Who has the world's biggest lithium mine open since the early 1900s.

Is that all of the sheet silicates? Or just the main types?

Hi Haji. Biotite is not worth a hell of a lot although does have a market for paints. However, you might find there is tantalite in there. Find a geologist locally.
