Abstract

One hundred and sixty rock samples of iron ore deposits and their host rocks from the Divrigi iron ore region were analysed for ten major and 31 trace elements, and 30 samples were analysed for rare earth elements. Statistical analyses divide rock types into different units (discriminant analyses) and several element associations (cluster and factor analyses). Individual rock types were also treated statistically. Different element associations and the geochemistry of the REE point to a genetic relationship between ore and host rocks and later hydrothermal overprints.

The interpretation suggests iron ores are closely associated with mafic ultramafic rocks. This exploration model has been applied iron ore deposits in central Anatolia, Turkey. The results stimulated first air-magnetic and later ground-magnetic field surveys leading to discovery of new iron ore occurrences which are currently being evaluated for their economic potential.

Coastal spreading of olivine to control atmospheric CO<inf>2</inf> concentrations: A critical analysis of viability
2009, International Journal of Greenhouse Gas Control
Qualitative proposals to control atmospheric CO₂ concentrations by spreading crushed olivine rock along the Earth's coastlines, thereby accelerating weathering reactions, are presently attracting considerable attention. This paper provides a critical evaluation of the concept, demonstrating quantitatively whether or not it can contribute significantly to CO₂ sequestration. The feasibility of the concept depends on the rate of olivine dissolution, the sequestration capacity of the dominant reaction, and its CO₂ footprint. Kinetics calculations show that offsetting 30% of worldwide 1990 CO₂ emissions by beach weathering means distributing of 5.0 Gt of olivine per year. For mean seawater temperatures of 15–25 °C, olivine sand (300 μm grain size) takes 700–2100 years to reach the necessary steady state sequestration rate and is therefore of little practical value. To obtain useful, steady state CO₂ uptake rates within 15–20 years requires grain sizes <10 μm. However, the preparation and movement of the required material poses major economic, infrastructural and public health questions. We conclude that coastal spreading of olivine is not a viable method of CO₂ sequestration on the scale needed. The method certainly cannot replace CCS technologies as a means of controlling atmospheric CO₂ concentrations.
