Is granite a euhedral? Euhedralprismatic zircons from granites commonly contain rounded cores inherited from source rocks, and high-grade orthogneisses contain patchy areas that yield reset metamorphic ages, rather than the original igneous age. ...
crucial to the diverse compositions of granite whereas fractional crystallization of granitic magmas has rarely effect on the compositional variation of granites.Therefore,the role of fractional crystallization in the evolution of granite should be appreciated in a limited scale rather than a large scale...
Why does rhyolite have smaller crystals than granite? Why is global biodiversity decreasing? Why does 'like dissolve like'? Why is marine biodiversity higher near coastlines? Why are there more cones than rods near the fovea? Why is there only one primer in PCF? Why do some people have extr...

1 holds. However, we acknowledge that estimation or measurement of the rate of shear strain locally between pores or crystals would be difficult (Deubelbeiss et al. 2011). Therefore, a more robust criterion for the viscous-to-brittle transition in crystal- or bubble-bearing magma would require...
