A model for the origin, ascent, and eruption of the lunar A17 orange glass magma has been constructed using petrological constraints from gas solubility experiments and from analyses of the lunar sample 74220 to better determine the nature and origin of this unique explosive eruption. Three stages of the eruption have been identified. Stage 1 of the eruption model extends from ~550 km, the A17 ...

The Norilsk ore district is one of the world leaders in production platinum metals. Long-term research focused on detection sulfide platinum-copper-nickel ores contributed to accumulation a large volume scientific material geology and mineralization area. Despite this, issue composition initial melt for ore-bearing intrusive complexes its degree enrichment with noble metals remains open. Intrus...

The Spirit landing site in Gusev Crater on Mars contains dark, fine-grained, vesicular rocks interpreted as lavas. Pancam and Mini-Thermal Emission Spectrometer (Mini-TES) spectra suggest that all of these rocks are similar but have variable coatings and dust mantles. Magnified images of brushed and abraded rock surfaces show alteration rinds and veins. Rock interiors contain </=25% megacrysts....

PURPOSE To report a case of corneal melting in a patient with fornix foreshortening being treated with reformulated generic diclofenac. METHODS Case report. RESULTS An asymptomatic 76-year old man presented with central corneal melting while being treated with reformulated generic diclofenac. This formulation did not contain the vitamin E derivative, tocophersolan, which has been felt to co...

We present the case of a young male that suffered from fungal corneal abscess and corneal melting. The patient was treated successfully by corneal cross-linking. Taking into account our experience from this case, we offer to consider corneal cross-linking as a therapeutic option in cases of fungal keratitis.

The question of whether basaltic rocks in continental flood basalt provinces are primary magmas or whether they are descended in general from picritic parent magmas is reviewed. It is suggested that the latter is more likely to be correct on the evidence of phase relations and the relative rareness of mantle materials with appropriate Fe/Mg ratios. Major element variations in the residual liqui...

We propose a model for the generation of average MORBs based on phase relations in the CaO-MgO-Al2O3-SiO2-CO2 system at pressures from 3 to 7 GPa and in the CaO-MgO-Al2O3-SiO2-Na2OFeO (CMASNF) system at pressures from 0.9 to 1.5 GPa. The MELT seismic tomography (Forsyth et al., 2000) across the East Pacific Rise shows the largest amount of melt centered at 30-km depth and lesser amounts at grea...
