While cow manure is excellent for growing vegetables it is not recommended to use fresh manure directly on the growing area because they will burn tender plant roots. Applied to an area alone with other organic materials as sheet compost. Dug into the garden and allowed to age for at least 30 days.
A batholith (from Greek bathos, depth + lithos, rock) is a large emplacement of igneous intrusive (also called plutonic) rock that forms from cooled magma deep in the Earth's crust. Batholiths are almost always made mostly of felsic or intermediate rock-types, such as granite, quartz monzonite, or diorite (see also granite dome).
The glassy rhyolites include obsidian, pitchstone, perlite, and pumice. The chemical composition of rhyolite is very like that of granite. The phenocrysts of rhyolite may include quartz, potassium feldspar, plagioclase feldspar, biotite, amphibole, or pyroxene.ertain differences between rhyolite and granite are noteworthy. Muscovite, a common mineral in granite, occurs very rarely and only as an alteration product in rhyolite. In most granites the potassium feldspar is microcline or microcline-perthite; in most rhyolites, however, it is sanidine.
