Fossil worm tubes of Cretaceous age preserved in the Bayda massive sulfide deposit of the Samail ophiolite, Oman, are apparently the first documented examples of fossils embedded in massive sulfide deposits from the geologic record. The geologic setting of the Bayda deposit and the distinctive mineralogic and textural features of the fossiliferous samples suggest that the Bayda sulfide deposit ...

When a steel pilot plant reactor was emptied, and left exposed to the humid summer atmosphere over a weekend, a heavy corrosion deposit formed on the inner surface. Because the process stream contained triflic acid (trifluoromethanesulfonic acid, CF3SO3H), the engineer wanted to determine whether the deposit contained triflate(s) [1]. The brown deposit was ground in a mortar and pestle. The maj...

SiC-coated graphite limiter material was eroded by a plasma during the plasma edge experiments in Alcator C, and redeposited on the molybdenum surface of the Janus probe. Surface morphology, composition and structure of the deposit was examined after a total exposure time of ~ 1000 seconds. The redeposited material typically showed a "layered" morphology. AES depth profiles revealed increased o...

[1] Mars Orbiter Laser Altimeter (MOLA) topographic data support the presence of an extensive Hesperian-aged volatile-rich south polar deposit, the Dorsa Argentea Formation (DAF) and related deposits, underlying the present Amazonian-aged cap. The eastern margin of these deposits displays further evidence for meltback, ponding, and drainage of the volatile-rich deposit. Channels leading from th...

We investigate the effectiveness of initiating deposit insurance at the outset of a banking crisis. Using a conjoint analysis approach that allows us to consider the simultaneous impact of multiple deposit insurance attributes and various counterfactuals, we ask a multinational sample of respondents how they would view hypothetical account profiles following the failure of a large competing ban...

The study of the fouling deposition of pink guava juice (PGJ) is relatively new research compared to milk fouling deposit. In this work, a new experimental set-up was developed to imitate the fouling formation in heat exchanger, namely a continuous flow experimental set-up heat exchanger. The new experimental setup was operated under industrial pasteurization temperature of PGJ, which was at 93...

the origin of the proterozoic choghart iron oxide deposit in the bafq mining district of central iran has been the subject of a long-standing dispute. some authors believe that it was formed from magma, while others suggest metasomatic replacement of preexisting rocks. the present study on the basis of new oxygen isotope, ree and geochemical data concludes that neither of these two hypotheses c...
