Compositional layering and a chromite lineation define a penetrative metamorphic foliation that almost certainly formed in the upper mantle. Although detailed petrofabric and mineral chemistry are presently lacking, it seems reasonable that the Cedars peridotite represents a slice of mantle tectonite that once formed the base of the Coast Range ophiolite, and not an abyssal peridotite tectonically emplaced within the Franciscan accretionary prism.", "description": "iii, 13 p.; maps col.; Plate: 1 Sheet: 15 x 15 inches", "publisher": {"@type": "Organization", "name": "U.S. Geological Survey"}, "author": [{"@type": "Person", "name": "Wentworth, Carl M. cwent@usgs.gov", "givenName": "Carl M.", "familyName": "Wentworth", "email": "cwent@usgs.gov", "identifier": {"@type": "PropertyValue", "propertyID": "ORCID", "value": "0000-0003-2569-569X", "url": "https://orcid.org/0000-0003-2569-569X"}, "affiliation": [{"@type": "Organization", "name": "Geology, Minerals, Energy, and Geophysics Science Center", "url": "https://www.usgs.gov/centers/gmeg"}]}, {"@type": "Person", "name": "Bailey, Edgar H.", "givenName": "Edgar H.", "familyName": "Bailey"}, {"@type": "Person", "name": "Blake, M.
