Felsic intrusive rocks of granite, adamellite, granodiorites and tonalities are widely used in construction, as the crushed rock is particularly of high quality. The fine grain varieties and polished slabs are used for massive structures. The porphyritic granites and rapakivi granites that contain large pink microcline are specially appreciated.

Rocks and minerals are familiar objects to all of us. We pick up attractive or unusual pebbles for our collections, we admire rocky mountain peaks, we speak of the mineral resources of our State and Nation. Rocks and minerals enter, either directly or indirectly, into our daily living. From them come the soils in which grow the grains, the ...
These rocks make up the majority of the earth''s crust. When an igneous rock is given a name, there are two characteristics that are important: composition and texture. Composition is defined as what the rock is made of and texture is how large the crystals are. Examples of igneous rocks are granite.
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. Granite is often said to have a "saltandpepper" appearance: the lightercolored minerals are quartz, potassium feldspar, and plagioclase feldspar, and the ...

The welldefined granite rock of Butte and Walkerville, Mont., affords conspicuous examples of goldbearing and silverbearing veins, originating apparently by lateral secretion from the body of the granite on each side. The Rainbow and Blue lodes especially appear to have derived their mineral and metallic contents from the granite in much the same way as the tinbearing lodes are formed ...
