The future demand for geological reference materials
Geological RMs (G-1 and W-1) were introduced in 1951 for the purpose of validating the accuracy of silicate rock analysis by dc arc spectrography. Since then the introduction of an array of other spectrographi...

Diverse contributing sources to chromitite petrogenesis in the Shebenik Ophiolitic Complex, Albania: evidence from new PGE- and Os-isotope data
Chromitites sampled from four different pseudostratigraphic levels of the Mesozoic Shebenik Ophiolite Complex, Albania, have low PGE totals <1 µg/g but show different types of PGE enrichment (Burgath et al., 2003...

An uncertainty budget for trace analysis by isotope-dilution ICP-MS with proper consideration of correlation
Isotope-dilution mass spectrometry (IDMS) is considered to be a method without significant correction factors. It is also believed that this method is well understood. But unfortunately a large number of diffe...

Relics of eclogite facies metamorphism in the Austroalpine basement, Hochgrössen (Speik complex), Austria
Retrograde eclogites and serpentinites from the Hochgrössen massif, Styria, are parts of the Speik complex in the Austroalpine basement nappes of the Eastern Alps. They are in tectonic contact with pre-Alpine...

Recognizing heterogeneous distribution of platinum group elements (PGE) in geological materials by means of the Re–Os isotope system
The identification of uncertainties caused by sample inhomogeneity, as distinct from those caused by sample preparation and measurement, is a challenging task. Use of chemometric methods to separate and estim...

The osmium isotopic composition of the Earth's primitive upper mantle
THE elevated abundances of highly siderophile elements in the Earth's mantle, relative to what would be predicted from metal–silicate equilibrium, have often been cited as evidence for the accretion to the Ear...

Geochemistry of polymetamorphic ultramafics (Major, Trace, Noble and Rare Earth Elements): An example from the Helvetic basement, Central Alps, Switzerland
Polymetamorphic ultramafic rocks in orogenic terranes rarely preserve relic structures or minerals from their former mantle stages. The determination of their protoliths and their tectonic evolution by chemica...

The thermal stabilities of alkali metal alkanoates. Part IV
The thermal stabilities of long-chain lithium and potassiumn-alkanoates from tridecanoate to eicosanoate have been investigated up to 873 K with a MOM derivatograph. The results obtained, together with available ...

Calorimetric test of purity II
Dynamic and stepwise purity test techniques were compared, and it was established that in dynamic measurement the sample in many cases can not be considered to be in a state of equilibrium from the thermodynam...

Calorimetric test of purity I
Relationships of various levels for the thermodynamical description of two-component eutectic systems have been investigated. It has been established that the van't Hoff relationship describes the melting curve d

The thermal stabilities of alkali metal alkanoates part III
Simultaneous DTA, TG and DTG analysis has been performed on potassiumn-alkanoates from pentanoate to dodecanoate in the range between room temperature and 873 K. Information has been obtained on the thermal decom...

On the thermal stability of alkali metal alkanoates II
Lithiumn-alkanoats from pentanoate (LiC5) to dodecanoate (LiC12) have been investigated with regard to their thermal stabilities. None of these salts are stable in the molten state when oxygen is present, but in ...
