Ophiolite Metamorphism and Ocean-Floor Metamorphism.
Journal of Geography (Chigaku Zasshi), 1995 Ophiolites of primary igneous origin have been more or less modified by later metamorphic processes, and there are several types of ophiolite metamorphism such as (1) the low-pressure type as recognized in ophiolites of the Mediterranean, Alps, Oman, Newfoundland, Chile, Taiwan, Borneo, California Coast Range, Hidaka Western Zone, and Horokanai, (2 ...

The structural, metamorphic and thermal history of the Sonnblick Dome, southeast Tauern Window, Austria [PDF]
, 1990 Within the southeastern Tauern Window, the Sonnblick Dome is a large, NE-verging, antiformal structure composed of orthogneisses of the Zentralgneis Complex.

Identifying airborne snow metamorphism with stable water isotopes [PDF]
<jats:p>Abstract. Wind-blown snow is a frequent phenomenon in high-elevation and polar regions which impacts the surface energy and mass balance of these areas.

metamorphism and deformation in the Belledonne Massif (Western Alps)
, 2021 The age and P–T conditions of Variscan high-P(HP) metamorphism in the Palaeozoic basement of the western Alps remain poorly constrained, but is nevertheless crucial to build a consistent tectonic scenario for the southeastern domain of the Variscan Belt.

Meteoritics &Planetary Science, EarlyView.Abstract The Tvären structure in southeastern Sweden has been listed as a confirmed marine‐target impact structure for decades. However, to date, no measurements and/or indexed data of planar deformation features in quartz grains from the structure have been published or any other unequivocal evidence of impact.

Geochronological and structural constraints on the Cretaceous thermotectonic evolution of the Kraishte zone (Western Bulgaria) [PDF]
, 2010 In the Kraishte region, near the junction of the Balkanides and Dinarides, late Early Cretaceous compression led to the thrusting of the Morava unit over the Struma unit.

Meteoritics &Planetary Science, EarlyView.Abstract A core drilled through shocked and faulted Archean granitoid gneisses and dolerites in the eroded peak ring of the 70–80 km diameter Morokweng impact structure intersects multiple centimeter‐ to meter‐wide clastic‐matrix breccias containing a polymict clast population of lithic and mineral clasts and altered, millimeter‐ to centimeter ‐size ...

, 1998 P(論文)It is shown on a basis of generalization of lateral and vertical distribution of P-T parameters in granulite-gneiss belts of various ages that the thermal gradient within the lower crust during granulite metamorphism is rather low, ca. 5-10℃/km. Two

Alpine Metamorphism of Mafic Rocks
, 1974 Metamorphosed mafic rocks in the Alps exhibit many characteristic mineral assemblages. They are used to study different phases of alpine metamorphism. The great variety of alpine metamorphosed mafic and ultramafic rocks is illustrated with a map of their
