The first consists of middle Proterozoic gneiss and upper Proterozoic sedimentary rocks that were regionally metamorphosed under low-pressure conditions during Middle Jurassic time, were intruded by the Late Cretaceous Hall Canyon granitic pluton, and were folded along NNW-trending axes during Late Cretaceous time. This group, called the Panamint metamorphic complex, makes up the core of the Panamint Mountains. The complex is cut by numerous west-dipping, low-angle normal faults that are locally intruded by the Miocene Little Chief stock. The second group consists of monolithologic breccias, called the Surprise breccia, derived from the local metamorphic rocks. The Surprise breccia forms the western slope of the Panamint Mountains north of Pleasant Canyon and forms the hanging wall of the west-dipping Surprise fault. Displacements along the fault, estimated from offset structures, are about 2,500 m down dip. The third group consists of the Nova Formation, which comprises fanglomerate, basalt, and minor breccia and which lies in the hanging wall of the west-dipping Emigrant fault. The fanglomerates contain abundant clasts of metamorphic and granitic rocks from the metamorphic complex. The three groups of rocks are separated from each other by intervening faults. The Panamint metamorphic complex is the structurally lowest group and is separated from the Surprise breccia by the Surprise fault. The breccia is separated from the structurally highest Nova Formation by the Emigrant fault. All these rocks lie above the regionally extensive Amargosa fault.\n\nThe difference in rock character among fanglomerates, breccias, and relatively intact metamorphic core rocks is readily visible in Thematic Mapper (TM) and Shuttle Imaging Radar (SIR-B) images. The TM image, which is sensitive to differences in mineralogic compositions of the rock types, distinguishes the metamorphic complex from the Surprise breccia because the breccias are more highly weathered than the metamorphic complex. The SIR-B image, which is sensitive to differences in surface roughness and topography, readily distinguishes between the breccia and the fanglomerate. The breccia is characterized by closely spaced, parallel drainages, whereas the fanglomerate contains a dense dentate drainage pattern. The combination of the images is a significant mapping aid in the central Panamint Mountains.\n\nMost of the uplift of the Panamint metamorphic complex, from a Late Mesozoic depth of about 10 km to ~3 km, probably occurred during displacements along the Amargosa and related faults. Some of these faults were intruded by the late middle Miocene Little Chief stock. The maximum possible uplift rate at this time was 17 mm/yr; the actual rate could have been lower if some uplift occurred prior to faulting. The metamorphic complex was largely unroofed by the time of deposition of the Nova Formation. Uplift of the range prior to, and partly contemporaneous with, Nova deposition resulted in formation of the Surprise breccia. The Emigrant fault formed late. The fanglomerates dip ~25\u00b0 eastward against the Emigrant fault, but this tilting appears to have resulted from aggregate rotation along several fault surfaces rather than from uniform eastward tilting of the entire Panamint Mountain block. Isolated remnants of Surprise breccia on ridge crests indicate that the unroofing of the metamorphic complex south of Wildrose Canyon probably was not completed until after the breccia-mass development.", "doi": "10.1130/MEM176-p345", "isbn": "9780813711768", "publisher": "Geological Society of America", "place_of_publication": "Boulder, CO", "publication_date": "1990", "pages": "345-362" }, { "id": "authors:tq268-vpj41", "collection": "authors", "collection_id": "tq268-vpj41", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20221102-150341940", "type": "book_section", "title": "Metamorphic zones in northern Vermont", "author": [ { "family_name": "Albee", "given_name": "Arden L.", "clpid": "Albee-A-L" } ], "contributor": [ { "family_name": "Zen", "given_name": "E-an", "clpid": "Zen-E-an" } ], "abstract": "The metamorphosed pelitic rocks in north-central and northwestern Vermont are strikingly different from those in northeastern Vermont. North-central Vermont is a schistose, regionally metamorphosed terrane, typical of the kyanite-sillimanite facies series of Miyashiro (1961), whereas northeastern Vermont is a hornfelsic, \"regional-contact\" metamorphosed terrane more typical of the low-pressure intermediate, or Buchan, facies series of Miyashiro (1961). These pronounced differences in the type of metamorphism\nmay be reflections of different times as well as different physical conditions of metamorphism. \n\nHigher-grade assemblages in the eastern part of the western metamorphic belt are extensively altered to lower-grade mineral assemblages, although similar higher-grade assemblages somewhat farther west have not undergone such alteration. This observation suggests the possibility that a younger, eastern metamorphic belt has been partially superimposed on an older, more westerly metamorphic belt and that the low-grade adjustment occurred synchronously with higher-grade metamorphism in the eastern belt. The available isotopic dates can be interpreted to indicate that the two belts were not formed simply as stages of a single period of metamorphism, but have substantially different ages. \n\nRegardless of their relative ages, distinct differences between the two belts imply that the physical conditions of metamorphism were different. Published assemblages have indicated a sequence of metamorphic reactions in eastern Vermont quite unlike those in western Vermont; leading one to expect that the difference in conditions between the two metamorphic belts might result in different chemical fractionation of Mn, Fe, and Mg between the phases. As will be shown, no differences in the sequence of metamorphic reactions can be demonstrated and the apparent differences between the two belts are due mainly to gross differences in rock composition. Moreover, the temperature dependency of the partition coefficients is so small that it is obscured by other effects.", "publisher": "Interscience Publishers", "publication_date": "1970" }, { "id": "authors:8343m-mzm77", "collection": "authors", "collection_id": "8343m-mzm77", "cite_using_url": "https://resolver.caltech.edu/CaltechAUTHORS:20141028-073725126", "type": "book_section", "title": "Continuous Garnet Zoning under Increasing and Decreasing Temperature Conditions, Kwoiek Area, British Columbia, Canada", "author": [ { "family_name": "Hollister", "given_name": "Lincoln S.", "clpid": "Hollister-L-S" }, { "family_name": "Albee", "given_name": "Arden L.", "clpid": "Albee-A-L" } ], "abstract": "Garnet porphyroblasts from five rocks, collected from within a 100-foot-square outcrop area\nin the Kwoiek area of British Columbia and differing only in the relative proportions of\nchlorite, staurolite, garnet, biotite, plagioclase, ilmenite, graphite, and quartz, were studied\nin detail with the electron microprobe.
