The Formation and Composition of Felsic Rocks
Felsic rocks, also known as silicic or acid rocks, are a significant geological feature of Tishomingo County. These rocks are rich in feldspar and silica, which contribute to their light color and high viscosity. Felsic rocks primarily consist of minerals such as quartz, orthoclase feldspar, and plagioclase feldspar. Their high silica content gives them unique properties and plays a crucial role in the geological makeup of the area.
Formation Process of Felsic Rocks
Felsic rocks form through a complex geological process that involves the cooling and solidification of magma deep within the Earth's crust. As magma rises towards the surface, it encounters various chemical and physical changes that ultimately lead to the formation of felsic rocks. The slow cooling of magma allows for the growth of large mineral crystals, resulting in a coarse-grained texture commonly observed in these rocks.
Composition of Felsic Rocks
Felsic rocks comprise approximately 70-75% silica, making them among the most silica-rich rocks on Earth. This high silica content imparts their characteristic light color, ranging from shades of gray to pink, white, or cream. Additionally, felsic rocks often contain traces of minerals such as biotite, muscovite, and amphibole, which contribute to their overall composition and appearance.
