    The Mineral sillimanite. Sillimanite is named in honor of Benjamin Silliman (1779-1864), noted chemist and the earliest professor to teach mineralogy at Yale University. Silliman was also the father in law of noted mineralogist and author James Dwight Dana. Gray, brown, yellowish-gray, white. Rarely colorless, light pink, or light purple.

    Jun 17, 2020 In Figure 3, kyanite inclusions occur in garnet in a rock that has only sillimanite in the matrix, indicating that the rock was previously in the kyanite stability field but that P-T conditions changed. When the matrix of the rock (including the garnet rim) equilibrated, the rock was in the silliminate stability field (Fig. 4).

    A dense (ρ~3.34 g cm -3 ) garnet sillimanite-rich metamorphic rock from the suevite breccia of the Ries impact crater was studied by scanning-electron microscopy and Raman microprobe spectroscopy. In the strongly shocked rock clast kyanite was formed from sillimanite under momentary high pressures of natural shock waves. Kyanite aggregates were found as thin (~0.3 2.0 μm) seams along grain ...

    Sillimanite is a grayish-blue aluminum silicate with an orthorhombic crystal system. It is trimorphic with andalusite and kyanite. All three have the same chemical compound but their atoms each arrange to create three different crystal forms. It appears as long, slender crystals without distinct terminations, in off-white, gray, brown, pale ...

    Sep 28, 2011 George Barrow identified patterns in the minerals found in these rocks, based on the appearance of characteristic index minerals (chlorite, biotite, garnet, staurolite, kyanite, sillimanite). His insight was that these index minerals were distributed in distinctive ways. The rocks of the Scottish Highlands are mostly metamorphosed sediments.

    In most andalusite and sillimanite schists, the types of polymorphs in veins correlate with Al 2 SiO 5 polymorph(s) in the host rocks, although vein polymorphs are texturally and compositionally distinct from those in adjacent host rocks; e.g. vein andalusite is enriched in Fe 2 O 3 relative to host rock andalusite.
