Unusual high-density and saline aqueous inclusions in ultrahigh pressure metamorphic rocks from Sulu terrane in eastern China
Primary high-density fluid inclusions were identified in garnet from ultrahigh pressure eclogite in the southern part of the Sulu terrane. They occur isolatedly or in cluster together with relatively low-densi...

Microanalysis of minerals by laser ablation ICPMS and SIRMS
Due to permanent re-equilibration processes that minerals undergo during dynamic processes within the earth, minerals build up concentration profiles – mainly from rim to core – which are ideal indicators of ...

O, H, C isotope study of rocks from the KTB pilot hole: crustal profile and constraints on fluid evolution
The pilot hole of the Continental Deep Borehole (KTB) drilling project is located in the Bavarian Oberpfalz at the western margin of the Bohemian Massif. The 4-km deep borehole penetrated various paragneisses ...

Carbon and oxygen isotopic covariations in hydrothermal calcites
Isotopic covariations of carbon and oxygen in hydrothermal calcites are quantitatively modeled in terms of the following three mixing processes: (1) mixing between two different fluids which leads to the preci...

Stable isotope (O, H, S) relationships in Tertiary basalts and their mantle xenoliths from the Northern Hessian Depression, W.-Germany
18O/16O, 34S/32S, and D/H ratios as well as vacuum-fusion H2O+ contents were measured for late Tertiary volcanic basaltic rocks ranging in composition from quartz tholeiites and alkali olivine basalts to melilit...

Stable isotope relations in an open magma system, Laacher See, Eifel (FRG)
18O/16O and D/H ratios have been measured for matrix glasses and phenocrysts from the zoned phonolitic Laacher See tephra sequence (11000 y.b.p., East Eifel volcanic field, FRG) to study open-system behaviour of...

The oxygen isotope composition of Hercynian granites and pre-Hercynian gneisses from the Schwarzwald, SW Germany
The oxygen isotope composition of 56 Hercynian granites and 42 pre-Hercynian gneisses has been investigated. In addition some mineral δ 18O data and 5 δD values of whole rocks have been obtained. The granites fro...

Very high CO2 cordierite from Norwegian Lapland: Mineralogy, petrology, and carbon isotopes
The most CO2-rich cordierite thus far encountered in nature with about 2.2 wt.% CO2 and 0.3 wt.% H2O occurs as large poikiloblasts in a strange non-foliated “reaction rock” that dissects well-foliated granulites ...

Constraints on the origin of Damaran granites by Rb/Sr and δ18O data
The mean (87Sr/86Sr) and mean (87Rb/86Sr) ratios of the intrusive granites from the North and South of the Orogen's Central Zone plot on straight lines. These are interpreted as areal isochrons indicating the tim...

The sulfur and carbon isotope composition of scapolite-rich granulites from southern Tanzania
Sulfur and carbon isotope data are presented of 15 granulite samples from the Furua Complex, southern Tanzania, in which scapolite is a primary and major rock-forming constituent (up to 30 vol%). From these da...

13C/12C-Verhältnisse in menschlichen Harnkonkrementen
Oxalate, uric acid, and phosphate stones have been analyzed for their carbon isotope composition. The oxalate stones show δ13C values between −17.0 and −19.5‰, the uric acid stones between −14.9 and −19.4‰, and t...

Fluid inclusion and carbon isotope study from bamble granulites (South Norway)
The carbon isotopic composition of CO2 from fluid inclusions in granulite facies rocks has been determined. The “primary” carbonic fluid — most probably being of Upper Mantle origin — appears to have δ 13C-values...
