WebbThe granitic intrusive bodies that generate these deposits are formed later as post-orogenic intrusions that are relatively reduced chemically, alkaline-tending and volatile-rich. These plutons fracture the surrounding rocks as they are intruded and the parallel fractures created give rise to the sheeted vein systems that are characteristic of these deposits. WebbIntrusive rocks are named and classified according to: Whether the body large ar small. Whether it has a particular geometric shape. Whether the rock formed at considerable depth or was a shallow intrusion. The geometric relationship of the intrusion to the country rock?

WebbThe bedrock geology of Yosemite National Park consists almost entirely of granitic rocks. Granite is an intrusive igneous rock, which means it crystallized from molten rock, called magma, miles underground. At these depths, magma is insulated by the rocks around it and cools very slowly, growing large interlocking crystals. WebbBatholiths are very large intrusive bodies, usually so large that there bottoms are rarely exposed.Sometimes they are composed of several smaller intrusions.
