... sources, oxygen fugacity conditions, temperatures, and halogen contents on which we evaluate the relationship between rare metal enrichment and magmatic-hydrothermal evolution of beryllium in pegmatites and granites through new results from zircon U-Pb isotopes, trace element compositions, and whole-rock...

... and that includes the average altitude of several watersheds. Computed ages assuming higher elevations are also presented in Supp. Table Cosmo. The 10 Be/ 9 Be and 26 Al/ 27 Al ratios were measured at the French national AMS facility ASTER. The 10 Be/ 9 Be beryllium data were calibrated directly...

...Zheng Ji; Wenchun Ge; Hao Yang; Yongzhi Wang; Haoran Wu; Zhichao Zhang; Yu Dong; Hongying Zhou; Yan Jing Abstract High-silica granites are significant carriers of highly incompatible elements and are closely associated with mineralization of the rare metal beryllium. Thus, understanding...

... by the dominant lithology along the channel and thus likely most strongly expressed in channel steepness. All samples were prepared using standard quartz separation and beryllium extraction techniques (see the Supplemental Material). Samples from catchments with Ordovician bedrock also required 1–3 hot...

... depends on the chemical composition of frame-forming cations: aluminosilicates are the least stable and undergo the phase transitions below 6 GPa; borosilicates preserve their initial crystal structure up to ~20 GPa; beryllium phosphates do not undergo phase 2 transformations up to 75 GPa. It has been...

... localities should be attributed to Devonian and Carboniferous postorogenic to extensional peraluminous A-type granitic magmatism, which is the major source of beryllium not only for the Pampean Ranges but for the whole country. Information on Be-geochemical distribution is lacking and little is available...

... metamorphic rocks in southern Jiangxi, South China. A pegmatite beryllium (Be), skarn beryllium-tungsten (Be-W), cassiterite sulfide tin-tungsten-beryllium (Sn-W-Be), independent fluorite, and lead-zinc (Pb-Zn) vein five-in-one model was developed for the prospecting of rare metals such as Be and W...

... and separated the quartz grains using the methods of Kohl and Nishiizumi (1992) . We then isolated the beryllium in the quartz and measured 10 Be concentrations at the PRIME Laboratory at Purdue University. With these in situ 10 Be concentrations, we then calculated catchment-averaged erosion rates using...

... analyses use the signal from Si + , some laboratories have used a multiply charged ion (Si 2+ or Si 3+ ). We collected data and constructed calibration curves for lithium, beryllium, and boron using these different normalizing species on synthetic basaltic glass and soda-lime silicate glass standards...

...Chen Liu; Ru-Cheng Wang; Robert L. Linnen; Fu-Yuan Wu; Lei Xie; Xiao-Chi Liu Abstract Beryllium is a critical metal typically concentrated in highly fractionated granitic rocks such as the leucogranites in the Himalaya. Here, we report beryl mineralization that was continuous from the earlier...

... were reduced to the number of total 10 Be atoms in each sample using the mass of low-background beryllium carrier added to each sample. A process blank, composed of the same mass of beryllium carrier only, was processed and measured with each batch of quartz samples. The 10 Be/ 9 Be measured ratios...
