THE EMPLACEMENT AND ORIGIN OF GRANITE – GeologynetOne, known as the magmatic theory, states that granite is derived by the crystal fractionation of magma. The second, known as the granitization theory states that granite is formed "in situ" by ultrametamorphism.
For Beginners: Basics of rock and mineral collecting; Rockhounding ArkansasQuartz has the chemical composition Si02. A rock is usually composed of 2 or more minerals in some physical combination, although some rocks are composed of only one mineral. Examples of rocks are limestone, sandstone, granite, or shale. (If you wanted to think of a comparison to food, minerals would be like flour and sugar, and a rock would be ...

Global Volcanism Program | AguaGeological Summary The symmetrical, forested Volcán de Agua stratovolcano forms an impressive backdrop to the city of Antigua, Guatemala, opposite from the Fuego and Aenango volcanoes. The isolated basalticandesite to andesite edifice makes it a prominent landmark visible from all directions.
Volcán de FuegoBeginning in 2002, the Volcán de Fuego entered a new active period, with more or less continuous activity, interspersed with monthly eruptive episodes. These episodes would typically send ash falling on communities within 20 km of the volcano, and lava flows about 1–2 km from the summit, and the occasional pyroclastic density current. [28]
