Exfoliating slabs of granite, on Half Dome in Yosemite National Park, USA. Exfoliating granite is a granite undergoing exfoliation, or onion skin weathering (desquamation).The external delaminated layers of granite are gradually produced by the cyclic variations of temperature at the surface of the rock in a process also called spalling.
Different specific granite types have differing propensities to weather, and so differing likelihoods of producing decomposed granite. The parent granite material is a common type of igneous rock that is granular, with its grains large enough to be distinguished with the unaided eye (i.e., it is phaneritic in texture); it is composed of ...
Exfoliated granite sheets in Texas, possibly caused by pressure release. Pressure release or unloading is a form of physical weathering seen when deeply buried rock is exhumed. Intrusive igneous rocks, such as granite, are formed deep beneath the Earth's surface.
Once there, if you're a newbie, head for Yosemite Falls, the great spigot of Yosemite Valley and North America’s tallest waterfall, a 2,425-foot medley of cascades down granite walls.

Granite domes are domical hills composed of granite with bare rock exposed over most of the surface. Generally, domical features such as these are known as bornhardts . Bornhardts can form in any type of plutonic rock but are typically composed of granite and granitic gneiss . [ 1 ]
Sicily is definitely one of my top spots in the country. I loved roaming Taormina's charming streets, taking a ferry to the Aeolian Island of Salina, and staying a few nights at Principe di Salina. 2.
