WebOct 10, 1985 · If Al is considered as a strictly inert component, the reaction biotite → chlorite produces a decrease of the ferromagnesian mineral volume of ∼ 13% (Ferry, 1979). This is not in agreement with petrographic observations of the rocks studied here, therefore writing of a chloritization reaction must take into account a volume increase. WebJan 1, 1998 · For the alteration of biotite to chlorite the replacement of potassium in the interlayer by a brucite-like layer and the subsequent increase in volume was …
WebExpert Answer. Suppose you find a rock in the field that has the reaction that you wrote out in question 5 b preserved. In other words, you have the mineral assemblage garnet-chlorite-biotite-staurolite preserved in the rock. Luckily, you also have both kyanite AND sillimanite in the rock as well. With that information and the P-T grid, what ... WebChlorite is present as pseudomorphs after biotite with inclusions of apatite, zircon, and opaques (Figure 4f). These rocks have undergone considerable deformation associated with metamorphic events, as clearly indicated by the microstructures observed in the major minerals as the simplectites that form as a breakdown product of K-feldspar ...
WebGranitic biotite from southeastern Australia alters to a mixture of chlorite (65%), sphene (10%) and epidote (10%) through a hydrothermal (330–340°C) reaction in which two … WebDec 15, 2015 · Reaction along the biotite grain boundaries has produced muscovite and minor chlorite. Most of the chlorite is disseminated throughout the bioitite along the mica cleavage planes. The centre of the biotite breakdown microstructure is marked by a Fe–Mg carbonate vein that also invades the mica.
