How to identify red granite (the Wisconsin state rock)
Granite is a type of igneous rock. This broad category of rocks forms when hot, molten rock cools down — as the rock cools, it crystallizes and solidifies. To identify an igneous rock that could be granite, look for rocks with crystals. Look for shiny, flat surfaces within the rock — these are the crystal faces. The rock … See more

Alkali feldspar granite - Wikipedia
Alkali feldspar granite, some varieties of which are called 'red granite', is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar (K-spar). It is a dense rock with a phaneritic texture. The abundance of K-spar gives the rock a predominant pink to reddish hue; peppered with minor amounts of black minerals.

Granite - Wikipedia
Granite is a coarse-grained (phaneritic) intrusive igneous rock composed mostly of quartz, alkali feldspar, and plagioclase. It forms from magma with a high content of silica and alkali metal oxides that slowly cools and solidifies underground. It is common in the continental crust of Earth, where it is found in igneous intrusions. These range in size from dikes only a few centimeters across to batholiths expo…
