...). The Presqueira pegmatite is a Li-Sn-Ta mineralized body mainly composed of albite, spodumene, quartz, muscovite and perthitic K-feldspar. The accessory minerals are petalite, cassiterite, columbite–tantalite and phosphates (fluorapatite, montebrasite, goyazite, vivianite and messelite). As regards to the host...

A single qualitative estimate of the composition of this late phosphate suggests that it is messelite ( Liferovich et al...
