The rocks of the Sokrisan granite are mostly early stage, those of the Weolaksan and Muamsa granites include both early and late stages, and the studied samples of the Susan granite are entirely late stage. These four Cretaceous granites have more than 70 wt% SiO2, high Rb/Sr ratios, ...
The structure and composition of granites provide clues to the nature of silicic volcanism, the formation of continents, and the rheological and thermal properties of the Earth's upper crust as far back as the Hadean eon during the nascent stages of the planet’s formation1,2,3,4. The tempe...
He was a native of Aberdeen and his heart yearned suddenly for the icy winds that whistled through the granite streets of that city. Here he was a prisoner, imprisoned not only by that placid sea, but by his hatred for that horrible old man. He pressed his hands to his aching head....
of pelites, xenotime-(Y) breaks down before the growth of garnet. This is then followed by the breakdown of HREE-rich clinozoisite to xenotime-(Y) at 560–610 °C, depending on bulk composition of rock, particularly the bulk CaO/Na2O ratio (Janots et al.2008). Because xenotime-(Y)...
Night finally falls, transforming rocks into moonlit ridges. Memory stirs and mind wanders to the hands of forgotten waller hefting the pink granite rocks of this roundel on high moor. A gathering, winds whisk clouds up, wraith-like tendrils whisper, grasp at the moor but fade into moon-grey...
