New density measurements on carbonate liquids and the partial molar volume of the CaCO 3 component
(Springer-Verlag, 2003-12)
Density measurements on nine liquids in the CaCO 3 –Li 2 CO 3 –Na 2 CO 3 –K 2 CO 3 quaternary system were performed at 1 bar between 555 and 969 °C using the double-bob Archimedean method. Our density data on the end-member ...
Characterization of non-equilibrium and equilibrium occurrences of paragonite/muscovite intergrowths in an eclogite from the Sesia–Lanzo Zone (Western Alps, Italy)
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2000-04)
Coexisting muscovite and paragonite have been observed in an eclogite from the Sesia–Lanzo Zone (Western Alps, Italy). The P - T conditions of this eclogite reached 570–650 °C and 19–21 kbar and the rocks show several ...
Adakite-like signature of Late Miocene intrusions at the Los Pelambres giant porphyry copper deposit in the Andes of central Chile: metallogenic implications
(Springer-Verlag, 2003-10)
Adakite-like features are recognized in the Late Miocene (~10 Ma) porphyritic intrusions of the Los Pelambres giant porphyry copper deposit, central Chile (32°S). Located within the southern portion of the flat-slab segment ...
Petrology of ultramafic lamprophyres from the Beaver Lake area of Eastern Antarctica and their relation to the breakup of Gondwanaland
(Springer-Verlag; Springer-Verlag Wien, 2002-03)
Mesozoic melilite-bearing ultramafic lamprophyres are developed as sill, dyke and plug-like intrusive bodies in the East Antarctic Beaver Lake area. They consist of varying amounts of olivine, melilite, phlogopite, nepheline, ...
High-temperature heat capacity and thermodynamic properties for end-member titanite (CaTiSiO 5 )
(Springer-Verlag; Springer-Verlag Berlin Heidelberg, 2001-04)
The heat capacity of end-member titanite and (CaTiSiO 5 ) glass has been measured in the range 328–938 K using differential scanning calorimetry. The data show a weak λ-shaped anomaly at 483 ± 5 K, presumably associated ...
Heat capacity and phase equilibria of hollandite polymorph of KAlSi 3 O 8
(Springer-Verlag, 2006-05)
The low-temperature heat capacity ( C p ) of KAlSi 3 O 8 with a hollandite structure was measured over the range of 5–303 K with a physical properties measurement system. The standard entropy of KAlSi 3 O 8 hollandite is ...
Rutile/TiO 2 II phase equilibria
(Springer-Verlag, 2003-05)
The transition between rutile and α-PbO 2 structured TiO 2 (TiO 2 II) has been investigated at 700–1,200 °C and 4.2–9.6 GPa. Hydrothermal phase equilibrium experiments were performed in the multi-anvil apparatus to bracket ...
Evidence for a magmatic origin for Carlin-type gold deposits: isotopic composition of sulfur in the Betze-Post-Screamer Deposit, Nevada, USA
(Springer-Verlag, 2005-08)
We report here new sulfur isotope analyses from the Betze-Post-Screamer deposit, the largest Carlin-type gold deposit in the world. Carlin-type deposits contain high concentrations of arsenic, antimony, mercury, tellurium ...
