... Oman. It contains two glaciogenic units, the Ghubrah Formation (723+16/−10 Ma) and the Fiq Formation (currently undated), that are separated by the volcaniclastic Saqlah Formation. An angular unconformity is present between the Ghubrah and Saqlah formations, indicating a significant time gap between...

...Jonathan Leather; Philip A. Allen; Martin D. Brasier; Andrea Cozzi Abstract The Fiq Member of the Ghadir Manqil Formation, Huqf Supergroup, Oman, is composed of ∼1.5 km of glacial rainout diamictites, mass-flow deposits, turbiditic sandstones, and slope and shelf sandstones and siltstones, overlain...

... elsewhere in Oman. The bulk of detrital zircons in the Huqf Supergroup originate from Neoproterozoic parent rocks. However, older Mesoproterozoic, Palaeoproterozoic and even Archaean zircons can be recognized in the detrital population from the upper Mahara Group (Fiq Formation) and Nafun Group, suggesting...

...) to a particular Neoproterozic glaciation. Moreover, if Oman’s Abu Mahara diamictites (Ayn, combined Fiq-Ghubrah, subsurface Ghadir Manqil formations) are all indeed Varanginian then Smith’s conclusions would require major revisions derived from Oman (e.g. his figures 4 – 6 , 8 and 13). The problematic...

... to lower Paleozoic sedimentary sequence that contains evidence for at least two large glacial events; i.e., the tillites of the Ghubrah and Fiq Formations. The age of the Huqf Supergroup is constrained by a U-Pb zircon age from an ash unit in the lower part of the group, which has been dated at 711.8 ± 1.6...

The differential effect of alloying elements on anisotropy might thus be an additional tool for better constraining the composition of the inner core, in addition to providing data on its thermal and textural history. In our current understanding, the formation of the Earth took place in a few tens of millions...

... vacancies facilitates the migration of silicon cations to Si2 sites that is accompanied by a redistribution of protons. This leads to the formation of OH-defects like V Si _Si2_V M3 and V Si _Si2_2V M3 that are responsible of the absorption bands B and C ( Fig. 1b ). Other OH-defects may also be involved...

As discussed above, with respect to the ε to γ phase transformation in iron, we propose here that the formation in a set of most similar dense layers (the 110, 11̅0, 020, and 002 Pbcm -layers) can be related to an entropy increase along the T -induced ε to Pbcm phase transformation.
