...”) that form the aureole, and outlined the respective increases in metamorphic grade toward the granite contact, thus identifying the effect of contact metamorphism. A certain group of greenstones, the cordierite-anthophyllite hornfelses of Kenidjack, just north of Cape Cornwall, have long been discussed...

... and Tobisch, 1992 ), are the best candidates to better define the exact timing relationship between the pluton-contact aureole system and deformation at the upper crustal levels. This paper focuses on the deformation features of strongly sheared carbonate hornfelses from two ductile high-strain zones...

... hitherto rarely been documented in ocean crust. Here, hornfelsic rocks from the sheeted dike–gabbro transitions at two tectonic exposures of fast-spreading East Pacific Rise crust at the Pito and Hess Deeps and in the Oman and Troodos ophiolites are described. These rocks record thermal metamorphism...

... Variscan granodiorite– monzogranite and early Cambrian calcic and dolomitic marble and calc-silicate and pelitic hornfelses. The δ 18 O values of the garnet and clinopyroxene in the prograde skarn are indicative of δ 18 O fluid compositions near 9.5–10.9‰. The compositions of clinoamphibole and biotite...

... and quartz in the mesosome were developed. Average T-P conditions of hornfels and melt genesis are 786 °C and 3.7 kbar. Back reactions that produced biotite occurred at somewhat lower temperatures. Whole-rock geochemistry suggests that the protolith of the hornfelsic rocks was likely a mixture of greywacke...

...John L. Mair; Richard J. Goldfarb; Craig A. Johnson; Craig J. R. Hart; Erin E. Marsh Abstract The Scheelite dome intrusion-related gold deposit, western Selwyn basin, Yukon, is hosted in hornfelsed metasedimentary strata that lie adjacent to the exposed apices of a monzogranite to quartz monzonite...

... is superimposed on earlier potassic alteration that remains preserved at deeper levels. The base of the Mesozoic sequence and shaly beds in the upper Naco Group section are pervaded with secondary biotite. Calcareous rocks in the Naco Group are altered to (1) pyroxene-epidote hornfelses and minor garnet-magnetite...

.... The hornfelsic textures appear to have been superimposed upon regionally metamorphosed rocks. Indeed, a few rocks contain aluminum silicate minerals that indicate a relic sillimanite isograd. Figure 1 shows the locations of andalusite- and sillimanite-bearing rocks, including an andalusite assemblage...
