Dear all we are currently looking for a sample of biotite with known Fe3+/Fe2+ ratio, preferably with 20-25% Fe3+/Fetot. Does anyone have some, or know where I might be able to find it? We aim at getting about 1 g of biotite powder for some experiments. Thank you in advance and Happy Easter! ******************************************************************* Bernardo Cesare Dipartimento di Geoscienze, Universita' di Padova Via G.
