Core samples from Middle Silurian pinnacle reefs in northern Michigan exhibit a regionally consistent assemblage of late diagenetic phases including geopetal diagenetic sediment, disseminated pyrite, pyrobitumen, rhombic dolomite cement, and equant calcite spar. High (>80°C) fluid inclusion homogenization temperatures and inclusions of Silurian-sourced oil in these diagenetic phases indicate th...

Our new method incorporates fluid pressure communication into inclusion-based models of elastic wave velocities in porous rocks by defining effective elastic moduli for fluid-filled inclusions. We illustrate this approach with two models: (1) flow between nearest-neighbor pairs of inclusions and (2) flow through a network of inclusions that communicates fluid pressure throughout a rock sample. ...

The mechanism of inclusion removal from liquid steel by gas bubbling and bubble attachment in the tundish is complex due to the great number of variables involved, and it is even more difficult to study because of the turbulent flow conditions. The main objective of this work is to analyze and improve the understanding of the alumina inclusion removal rate by bubble attachment and by gas bubbli...

introduction arefi quartz-bearing conglomerate (middle jurassic) is situated within binalud structural zone. the unit is trending nw-se located 25 km south of mashhad. more than 97% of the pebbles are quartz as mono-crystalline, poly-crystalline, and minor fragments of chert, quartzite, and mica schist. less that 3% of the remaining minerals are feldspar, mica, chlorite, hornblende, tourmaline,...

kalchouyeh area in southwest of naein is located in the urumieh-dokhtar volcano-plutonic belt. mineralization occurred mainly as disseminations and veinlets hosted by trachy-andesite and pyroxene andesites. for mineralogy, alteration, fluid inclusion and geochemical studies, the two major mineralized zones: a (larger vein) from the north-northwest and b (smaller vein) from the east-southeast of...

During the course of experiments to investigate whether the addition of heat-denatured 7S y-globulin to rheumatoid leucocytes would produce transformation of the lymphocytes, an interesting phenomenon was observed. No specific stimulation of the lymphocytes was seen, but intracellular inclusions in neutrophils and macrophages, accompanied by extracellular bodies, were noted after culture of the...
