| 説明 | Chlorite schist (greenschist) from California, USA.Chlorite schist is a moderately common, intermediate- to high-grade, foliated metamorphic rock. It is principally composed of chlorite, a group of silicate minerals with a greenish-gray color. This example is from California's Pelona Schist. The precursors were deep-water marine, fine-grained, siliclastic sedimentary rocks. The rock also has some albite feldspar.Stratigraphy: Pelona Schist, undetermined age (possibly Cretaceous or Paleocene)Locality: lower plate rocks beneath the Vincent Thrust Fault, San Antonio Canyon, southern flanks of the San Gabiel Mountains, San Bernardino County, southern California, USA |
