The Mineralogy And Chemistry Of Micrometeorites
Prior to their retrieval from low Earth orbit (LEO), the individual solar cells that make up the 'V2' solar array panel from the Huhble Space Telescope (HST) were prone to hypervelocity (>5 km/s ) impact damage from micrometeoroids and space debris. The analysis of such passive collector surfaces …

Clay mineralogy of the southwest equatorial Atlantic sediments
… the partial grain-size distribution and (2) the mineralogy of the clay/fine silt size fractions of the equatorial Atlantic bottom sediments. From these data, it was hoped to find the controlling factors for the size distribution and mineralogy of the bottom sediments. That is, whether the …

Mineralogy-based global anthropogenic combustion-iron emission inventory
… emissions which are better constrained and have mineralogy-based solubility approach. Here we show that anthropogenic combustion-iron emissions can be about 1 Tg Fe/yr in the fine fraction, 10 times higher than all previous inventories. A large part of the difference is attributed to metal …

Geochemistry and mineralogy of selected Atlantic Ocean basalts
Bulk rock compositional variations in lavas from four localities in the Atlantic Ocean are evaluated quantitatively in terms of fractional crystallisation and partial melting models. Samples studied are from the Mid-Atlantic Ridge at 36°49 'N (FAMOUS), from the Islas Orcadas fracture zone on the …

Environmental controls on the skeletal mineralogy of marine calcifiers
… in the low-salinity setup. Although the skeletal mineralogy of calcifiers is generally tied to their phylogenetic history, the skeletal mineralogy, growth rates and skeletal production of many calcifying taxa are affected by the ambient Mg/Ca ratio, temperature and salinity. To test whether …

Characterization of lunar crust with moon mineralogy mapper data
This dissertation has three main focuses: (1) identify the distribution of a new rock type (Mg-spinel lithology) on the Moon and explore the likely petrogenesis of Mg-spinel; (2) investigate the presence of olivine in the crater central peaks and analyze the sources of olivine; (3) determine the …

Mineralogy, Chemistry & Flux of Suspended Sediments in Himalayan Rivers
The flux and composition of river suspended sediments contain valuable information on processes including erosion rates, the composition of the eroded bed rocks, chemical weathering and sediment storage and sorting within river channels. In this thesis, samples from the Kosi River in Nepal (a major …

Geothermal reservoir characterisation using automated mineralogy; implications for CO2 sequestration
… Iceland were analysed using SEM based automated mineralogy to determine any benefits this methodology may provide for drill cutting analysis in geothermal exploration, such as identification of minerals used in geothermometry, as well as any possible benefits in understanding CO2and H2S …

Petrology and mineralogy of certain portions of the Fredericktown deposits
<p>"The Fredericktown area is part of the 'Lead Belt' district of southeastern Missouri, the major lead-producing region in the world for fifty years. The district is a typical example of the Mississippi Valley Type deposits. The ores occur in Upper Cambrian sediments overlying Precambrian …

The compressive strength of fly ash concrete and its mineralogy
The use of fly ash as a cement extender in portland cement concrete is well established. Strict requirements are set for the fly ash on its physical properties and chemical composition to ensme its successful application as a partial replacement material for cement. An investigation was undertaken …
