Biotite rough is probably the most affordable option; even biotite specimens containing emerald go for $0.04-$0.60 per carat at wholesale. Beaded strands of biotite are usually around $10 each. Finished beaded bracelets start at $10 and go up to around $50, unless the piece includes pricier metal or gems.Web

Chl1b interlayered with biotite exhibits a similar orientation to biotite (same axial zone in STEM, Figs. 8b, 9b) and grows by two mechanisms: (1) insertion of a brucitic layer (light gray level) in the former biotite interlayer and (2) dissolution of two tetrahedral layers of biotite to form chlorite (Fig. 9f, i), as described by Veblen and ...Web

Biotite is a mineral found in many rocks, but you may not recognize its name because it's often lumped together with other related minerals under the name "mica."Mica is a group of phyllosilicates or sheet silicates characterized by forming parallel sheets of silicate tetrahedrons composed of silicon oxide, Si 2 O 5.Various forms of mica have …Web

Biotite shows significant variations in the F and Cl abundances on the local scale of individual intrusions, extrusions and also at times on the thin-section scale. This variation is responsible for biotite equilibration with fluids. The high concentration of F (0.80–7.11 wt%) and Cl (0.44–1.56 wt%) in biotite are usually ascribed to the ...Web
