Its bounding Cenozoic faults post-date Early Jurassic to Cretaceous top-S (SW) nappe stacking and high-to ultrahigh-pressure metamorphism within the gneissic units of the Rhodope Mountains, and they obscure the original relationships of the Rhodope core complex with the neighbouring units (Burg et al 1996;Turpaud 2006;Perraki et al 2006;Mposkos & Krohe 2006).

“…Despite an extensive search for new UHPM indicators, coesite and diamond remain the most reliable indicators among others. Diamond inclusions are quite rare and have been identified so far only in a limited number of localities (Sobolev & Shatsky, 1990;Massonne, 1999;Mposkos & Kostopoulos, 2001;Van Roermund et al, 2002;Mposkos & Krohe, 2006;Perraki et al, 2006), whereas the presence of coesite has been confirmed for 18 complexes (Chopin, 2003). Unfortunately, the complex metamorphic history of UHPM rocks often erases the peak metamorphic assemblages and prevents reliable estimation of the peak metamorphic conditions.…”

Laser Raman microspectroscopy was applied to quartz inclusions in coesite-and diamond-grade metapelites from the Kokchetav ultrahigh-pressure metamorphic (UHPM) complex, Northern Kazakhstan, and diamond-grade eclogite xenoliths from the Mir kimberlite pipe, Yakutiya, Russia to assess the quantitative correlation between the Raman frequency shift and metamorphic pressure. Quartz crystals sealed in garnets have a higher frequency shift than those in the matrix. Residual pressures retained by quartz inclusions depend on the metamorphic history of the garnet host. The Raman frequency shift of quartz inclusions in garnet from coesite-grade and diamond-grade metamorphic rocks shows no systematic change with increasing peak metamorphic pressures. The highest shifts of the main Raman bands of quartz were documented for monocrystalline quartz inclusions in garnets from a diamond-grade eclogite xenolith. Calibrations based on experimental work suggest that the measured Raman frequency shifts signify residual pressures of 0.1-0.6 GPa for quartz inclusions from coesite-grade metapelites from Kokchetav, 0.1-0.3 GPa for quartz inclusions from diamond-grade metapelites from Kokchetav, and 1.0-1.2 GPa for quartz inclusions from the diamondgrade eclogite xenoliths from the Mir kimberlite pipe. Normal stresses and internal (residual) pressures of quartz inclusions in garnet were numerically simulated with a 3-shell elastic model. Estimated values of residual pressures are inconsistent with the residual pressures estimated from the frequency shifts. Residual pressure slightly depends on P-T conditions at peak metamorphic stage. Laser Raman microspectroscopic analysis of quartz is a potentially powerful method for recovering an ultrahigh pressure metamorphic event. Monocrystalline quartz inclusions yielding a residual pressure greater than 2.5 GPa might indicate the presence of a former coesite.

“…Carbonates are distinguishable by their diagnostic Raman spectra (Bischoff et al, 1985;Burke, 2001;Gillet et al, 1993;Frost & Dickfos, 2007;Liu & Mernagh, 1990;Perraki et al, 2006;Scheetz & White, 1977;Williams et al, 1992 and references therein). However, the pressure dependence of the vibration frequencies is well known only in the case of particular carbonates (Gillet et al, 1993).…”

“…Inclusions in robust minerals that point to UHPM comprise diamond (C), coesite (SiO 2 ), TiO 2 polymorph with a-PbO 2 structure. Because of the generally very small size of the UHPM inclusions, which are close to the optical limit, analytical techniques for the accurate investigation of these inclusions are largely confined to transmission electron microscopy (TEM) (Dobrzhinetskaya et al, 2006;Hwang et al, 2001Hwang et al, , 2004Hwang et al, , 2005Langenhorst, 2003) and Raman spectroscopic point analysis and mapping (Korsakov et al, 2007;O'Brien & Ziemann, 2008;Ogasawara et al, 2002;Perraki et al, 2006Perraki et al, , 2007.…”

The presence of aragonite in polycrystalline carbonate inclusions in garnet in diamond-grade metamorphic rocks from the Kokchetav Massif, N. Kazakhstan was identified for the first time by means of Raman analyses and mapping, cathodoluminescence images and optical and scanning electron microscopy. Aragonite appears within the inclusions as dirty, chaotically oriented materials surrounded by a clean monocrystalline calcite shell; the grain boundary between the host-garnet and the aragonite-bearing inclusions is often characterized by a wavy or amoeboid shape; no cracks occur around the aragonite-bearing inclusions; no significant shift in the main aragonite Raman band was measured. These observations indicate that residual pressure within the inclusion is minor. These features are inconsistent with an origin of aragonite at peak metamorphic conditions (6 GPa) by decomposition of dolomite.
