WebNov 1, 2001 · Granitic rocks were classified into magnetite-series and ilmenite-series by Ishihara (1977). Ishihara recognized that in Japan there is a distinct spatial distribution of granitic rocks that contain magnetite—coexisting with ilmenite—and those that contain ilmenite as the only Fe–Ti oxide. WebThe rock is further characterized by its alternating light and dark bands of minerals. It forms from volcanic rock, shale, or granitic. Quartz is typically abundantly found in gneiss. The bands that form on gneiss rock are due to the various rocks that are a part of its make-up. The use of the word gneiss dates back to the mid-1700s.
