Biotite mica: The mineral Biotite information and pictures

Biotite is a common rock-forming mineral, and is especially noted in metamorphic rocks such as schist and gneiss. It is also found in igneous rock such as granite s and rhyolites. Biotite is also the primary mica in rare earth pegmatite s.

Phase relations of biotite and stilpnomelane in the …

Phase relations of biotite and stilpnomelane and associated silicate minerals have been studied in rocks of the greenschist facies, chiefly from Otago, New Zealand and western Vermont, but also from Scotland, Minnesota-Michigan iron range, and northwest Washington. That stilpnomelane in the greenschicht facies crystallizes initially with nearly all iron in the ferrous state is indicated by ...

Rates of Biotite Weathering, and Clay Mineral …

 · For Watersheds 2 and 34, the mineral weathering rate results are geochemically unreasonable when the biotite and HIS rates are coupled (Table 3). This scenario yields calculated rates for allanite, garnet, and biotite weathering that are negative, indicating formation of these primary minerals during weathering, which is geochemically unreasonable.

Partially kaolinitized biotite from Brighton, New Zealand, was studied by using transmission and analytical electron microscopy (tem and aem). Kaolinite occurs in two distinct modes: (1) as 50-300-Å-thick packets of layers interstratified within biotite and (2) as two-layer units (14 Å) irregularly interlayered within biotite.
