Sentence examples for alteration phase from inspiring English sources
At 150°C and below boron is removed from the seawater and is incorporated into brucite, which is the dominant alteration phase.
The second most common alteration phase were Fe- oxy)hydroxides (e.g., lepidocrocite) usually oFe- oxyhydroxidesrance or forming needle-like (Fig.g.c) and plepidocrocite several tens of nm thin and several μm long.
The matrix olivine is not primary to the meteorite, which suggests its formation through partial dehydration of the phyllosilicate, and therefore indicates that thermal metamorphism was subsequent to a preceding aqueous alteration phase.
The microstructures were not greatly affected by cooling rates between 1 and 5 °C/min or by introducing 10 times as much Cs and Sr. Protracted leach tests at 90 °C showed surface alteration as evidenced by SEM and particularly transmission electron microscopy; the main alteration phase was a Zn aluminosilicate but several other alteration phases were evident.
In three of the samples analyzed, the concentration of REEs for primary uraninite are higher than those for their corresponding secondary uranium alteration phases.
Based on the XPS (oxidation state of Ni) and SEM (abundance of Fe- and the absence of Ni alteration phases) results it is possible to construct an order of apparent stability of studied alloys and metals.
The PUF column volumetric water content was observed to increase steadily during the test because of water accumulation associated with alteration phases formed on the surfaces of the glasses.
The intrusive was emplaced within a sequence of earlier Proterozoic mafic intrusives and meta-volcanics during the Giles Event (1085 1040 Ma) and subsequently ductile-deformed and strongly overprinted by hydrous alteration phases, predominantly amphiboles.
Based on the results reported here, the latter may be attributed to the differing REE abundances between primary ore and associated alteration phases, and/or is related to varying fabrication processes adopted during production of UOC.
Subjects on SBR also had decreased plasma glucuronide and sulfate metabolites and an increase in urinary sulfate metabolite, suggesting an alteration of phase II metabolism.
On the other hand, a topological alteration of phase space occurs when a change in parameter values cause the number or stability of steady states to change.
