WebSillimanite occurs as a constituent of high-temperature metamorphosed rocks containing clay. In contact metamorphosed rocks it may occur in silimanite-cordierite gneisses or sillimanite-biotite horfels. In silica poor rocks, it may be associated with corundum.

WebA peak around re tention time 4.1 min was present in all chlorite standard chromatograms (Fig. 2) because the purchased chlorite standard was found to be 80% sodium chlorite and 20% sodium chloride. Chloride standards were therefore run and a strong peak at retention time around 4.1 minutes appeared on the chromatograms (Fig. 5) WebMore often found as micaceous flakes or tablets with irregular outlines.

WebChlorite is a common to abundant mineral in low- to intermediate-grade metamorphosed mafic and ultramafic rocks. It is particularly abundant in altered sea floor basalts and may provide a vehicle by which water is subducted into the upper mantle. Inasmuch as water is a … roll of soundproof foam
