The Shap granite a distinctive coarse-grained granite with large pink orthoclase feldspar was intruded late in the Caledonian orogeny around 394 million years ago. The granite had a complex evolution involving multi-stage addition of basaltic magma to the magma chamber and assimilation of country rock.

What are Pegmatite Minerals

Apr 15 2015 · Granite pegmatites can be complex in composition and contain a diverse suite of exotic minerals and tend to be enriched in what geologists call "incompatible elements" or "rare elements." These include cesium rubidium lithium beryllium tantalum niobium tin boron and zirconium along with a few others.

Granodiorite rock Britannica

Granodiorite medium- to coarse-grained rock that is among the most abundant intrusive igneous rocks. It contains quartz and is distinguished from granite by its having more plagioclase feldspar than orthoclase feldspar its other mineral constituents include hornblende biotite and augite.The plagioclase (andesine) usually forms twinned crystals sometimes wholly encased by orthoclase.

Mica Minerals are Major Rock Forming Minerals

Mica Minerals are Major Rock Forming Minerals. Mica minerals are major rock forming minerals found in gneiss schist and granite. The mica group includes muscovite mica and biotite mica. They usually form in layers of sediment on ocean floors. Weathering of continental rocks breaks large and small chunks of rock off the larger older rocks.
