So, one fine morning, I ascended the fright of granite steps, with the President's commission in my pocket, and was introduced to the corps of gentlemen who were to aid me in my weighty responsibility, as chief executive officer of the Custom-House. I doubt greatly-or, rather, I do ...
granite (redirected fromGranite biotite) Thesaurus Encyclopedia gran·ite (grăn′ĭt) n. 1.A common, coarse-grained, light-colored, hard igneous rock consisting chiefly of quartz, orthoclase or microcline, and mica, used in monuments and for building. ...
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)...

The composition of Hadean and early Archaean crust would also have been very different and included rock types such as ultramafic komatiites that are not formed in the present day40. Our experimental results, with H2O2 generated from modern rock types spanning felsic to ultramafic (Fig. 2),...
