A calcite-rich block in nephelinitic agglomerate at Oldoinyo Lengai comprises Sr-calcite, apatite, fluorite, a Ba-Mn oxide akin to romanrchite, and a distinctive Mn-Fe spinel. Formerly reported as sC3vite, on textural, mineralogical and stable isotope grounds it is now re-interpreted as a highly-altered natrocarbonatite lava. An implication of this study is that natrocarbonatite is not just a m...
1) Composition and quality of the in situ 2) Controls on distribution and volume of petroleum, both geographically and within a given borehole, 3) Water saturation and potential for internal or external water production, 4) Rock type and mineralogical composition for log calculations, lateral location and completion optimization, 5) Natural fracture distribution and porosity types, 6) Compartme...
CheMin is a miniature X-ray diffraction/X-ray fluorescence (XRD/XRF) instrument that is included in the payload of the Mars 2009 Mars Science Laboratory mission. A portable CheMin prototype was built to test the capability of the instrument for remote in-situ mineralogical characterization of geological materials. The instrument was successfully deployed at a variety of Mars analog sites in Dea...
In the eMinerals project we use computational modelling to research mineralogical processes at an atomistic level, providing information on transport and immobilisation processes of pollutants, including radioactive waste. Prior to the eMinerals project most calculations where undertaken on so-called model systems. With the new grid tools, available within the eMinerals project, we are instead ...
