Coesite in clinopyroxene in the Caledonides and its implications for geodynamics

  title={Coesite in clinopyroxene in the Caledonides and its implications for geodynamics},
  author={David C. Smith},
Coesite is reported for the first time from the Caledonide orogen. It occurs as inclusions in clinopyroxene in the dolomite-eclogite at Grytting, Norway, and provides valuable new evidence to support the hypothesis of extremely high pressure (≥30 kbar) in certain Norwegian eclogites. This finding has implications for the geodynamics and kinetics of the concepts of microscale intracrystalline tectonic overpressure and of macroscale local or regional tectonic overpressure, and for the hypotheses… 
Coesite in eclogites of the Lanterman Range (Antarctica): Evidence from textural and Raman studies
Quartz pseudomorphs after possible retrogression of coesite were recognized petrographically within garnets of mafic eclogites from the Lanterman Range (Antarctica). In one of the quartz pseudomorphs
Evidence for UHP metamorphism of eclogites from the Altun Mountains
Ultrahigh pressure (UHP) metamorphism refers to metamorphism that has occurred at pressures for the stability of coesite. The polycrystalline quartz inclusions showing the characteristic texture
Eclogite rheology: Implications for subducted lithosphere
Eclogite, the high-pressure equivalent of basalt, is common in ultrahigh-pressure metamorphic terranes and constitutes the oceanic crust after it is subducted into the mantle. We present here first
A vestige of very high-pressure (ca. 28 kbar) metamorphism in the Variscan Bohemian Massif, Czech Republic
Pyropic garnetite from the Podolsko Complex, south Bohemian Moldanubian Zone, Bohemian Massif, records very-high pressure (28kbar, 830 deg.C)conditions of formation of the initial mineral assemblage.
Microdiamonds in ultrahigh-pressure metamorphic rocks
Since the first report of microdiamonds of metamorphic origin in crustal rocks of the Kokchetav Massif, northern Kazakhstan, diamonds have been described from several other ultrahigh-pressure (UHP)
Exhumation Processes in Oceanic and Continental Subduction Contexts: A Review
Although the exhumation of high pressure (HP) and ultrahigh pressure (UHP) rocks is an integral process in subduction, it is a transient process, likely taking place during the perturbation in
The Maksyutov Complex: The first UHP terrane 40 years later
Radial fractures around quartz inclusions in garnets from the Maksyutov Complex were fi rst described nearly 20 years before coesite in crustal rocks was recognized elsewhere as evidence for
Tracing the Extent of a UHP Metamorphic Terrane: Mineral-Inclusion Study of Zircons in Gneisses from the Dabie Shan
Coesite inclusions in zircon from the country-rock orthogneiss of the southern Dabie ultrahigh-pressure terrane, central China were identified by Raman spectroscopy and electron microprobe
Origin and Exhumation of UHPM Rocks their Tectonic Significance
Within the continental collisional orogens of different age more and more occurrences of ultrahigh pressure metamorphic rocks of crustal origin are being recognized recently all over the world.


An Experimental Study of Tectonic Overpressure in Franciscan Rocks
Approximately 4 kb tectonic overpressure was required, according to one theory, for the formation of jadeite-aragonite-bearing rocks of the Franciscan. Strength of two common Franciscan rocks—massive
Evidence of Precambrian continent–continent collision in Western Norway
Norwegian gneiss eclogites are formed in situ within the temperature–pressure range 300–800 °C, 8–22 kbar. The regional KD(FeO/MgO)ga+cpx distribution pattern indicates an increasing P–T trend
A tectonic model for the metamorphic evolution of the Basal Gneiss Complex, Western South Norway
A review of currently available information relevant to the Basal Gneiss Complex (BGC) of Western South Norway, combined with the authors’own observations, leads to the following conclusions. 1.
Cation vacancies and the crystal chemistry of breakdown reactions in kimberlitic omphacites
The degree of alteration in clinopyroxenes from eclogitic inclusions in South African kimberlites is directly related to the deviation from stoichiometry of remnant unaltered areas in individual
Metastable growth of coesite in highly strained quartz
Coesite has been produced outside its stability field in highly strained samples of Dover flint. Large crystals grew in nine cylindrical samples compressed more than 50% at a strain rate of 10−4
