Andesite is an extrusive igneous rock that has a porphyritic texture. Physical and Chemical Properties 1. A compound is a substance made of 2 or more elements that have been chemically combined (ex. the chemical properties of magma are the chemical properties of whatever it contains but only if it is broken down - otherwise it is really, really hot melted rock. Characterized by a wide range of chemical compositions, with high temperature, and properties of a liquid. Because many of the properties of a magma (such as its viscosity and temperature) are observed to correlate with silica content, silicate magmas are divided into four chemical types based on silica content: felsic, intermediate, mafic, and ultramafic. Magmas vary in their chemical composition, which gives them—and the volcanoes that contain them—different properties. 11 Photomicrograph of Granite Classification of Igneous Rocks Based on Mineral Composition and Texture Textures-reflect rate of cooling• Phaneritic-mineral crystals are visible e.g. Boiling Point _____ 5. Mafic magmas are low in silica and contain more dark, magnesium and iron rich mafic minerals, such as olivine and pyroxene. How does chemical composition affect the properties of lava? Physical and chemical properties. These properties can be used to identify a substance or to predict how it will behave. Physical and chemical properties of magma. The minerals that make up igneous rocks crystallize at a range of different temperatures. The crust is very thin, relative to the radius of the planet. The major ingredient in magma is silica (50-70%), a compound made up of particles of the elements oxygen and silicon. Compounds. Mafic is a term used to describe both minerals that are rich in iron and magnesium and rocks that are rich in those minerals. Properties of Magma Physical & Chemical Properties An element is a substance that cannot be broken down into other substances (ex. As magma approaches the surface and the overburden pressure drops, dissolved gases bubble out of the liquid, so that magma near the surface consists of materials in solid, liquid, and gas phases..

In addition to these immediate dangers, volcanic activity produces secondary effects such as property damage, crop loss, and perhaps changes to weather and climate. Properties of Magma Chapter 7 Section 2. Common examples of mafic minerals include olivine, biotite, hornblende . 5. zIntrusive or plutonic igneous rocks wherein the magma crystallizes at depth in the Earth. . A. Nevertheless, the complexity of these physical and chemical responses requires an even more generalized picture of magma transport . Magma is a mixture of liquid rock, crystals, and gas. The EOS relates the density of a sub- Collect along which aspect they are found at which is. Magma is molten rock deep underground. Thus, as minerals crystallize from magma, the composition of the magma changes. The sequence in which minerals crystallize from a magma is known as the Bowen reaction series (Figure 3 . 3.1b Minerals are formed inorganically by the process of crystallization as a result of specific environmental conditions. Possible chemical leftovers from early Earth sit near the core . substance made up of 2 or more elements. Physical or chemical properties can be used to identify a substance or predict how it behaves. the properties of the magma from which it formed. Magma Thermodynamic Properties 117 3.1. Magma composition, in particular the contents of silica and volatile compounds (mostly water and CO2) will determine the physical properties of the melts, such as density and viscosity. The viscosity of magma depends upon its silica content and temperature. QAPF Diagram for Dacite: A QAPF diagram is a method of classifying igneous rocks on the relative abundance of quartz, alkali feldspar, plagioclase feldspar, and feldspathoid minerals. A summary of these properties is presented in the following slide. It changes the temperature. All substances are made up of Elements. Magma consists of liquid rock that usually contains suspended solid crystals. and in the way they were formed. Igneous rocks, which form from magma, have diverse characteristics that provide geologists with clues about the environment in which these rocks formed. Explosions Classify volcanic eruptions according to the physical and chemical properties of their magma Learn about the different kinds of volcanic eruptions. What are magma and lava made up of? Magma (Characteristics, Types, Sources, and Evolution) A magma consists mostly of liquid rock matter, but may contain crystals of various minerals, and may contain a gas phase that may be dissolved in the liquid or may be present as a separate gas phase. What is the chemical composition of magma? Chemical Composition of Andesite Andesite is an intermediate sub-alkalic rock with SiO2 contents ranging between 57 and 63 wt. This lesson introduces students to the physical and chemical properties of magma and lava. Physical or chemical properties can be used to identify a substance or predict how it behaves. The more silica magma contains, the higher its viscosity. Rhyolitic magmas usually have higher gas contents than basaltic magmas. Most of the time, a xenolith is a rock embedded in magma while the magma was cooling. capacity and are inextricably bound to the thermal evolu-. Rhyolitic magma -- SiO2 65- 75%, low in Fe, Mg, Ca, high in K, Na Different types of Magma have differ in the values of physical properties like temperature, viscosity, gas content, etc. Andesite Magma: This magma has a chemical composition of roughly 60% and it forms an andesite rock when it crystallizes. A chemical precipitate is a chemical compound—for instance, calcium carbonate, salt, and silica—that forms when the solution it is dissolved in, usually water, evaporates and leaves the compound behind. The proportion of three-dimensional structural units increases at the expense of chain and sheet units as the magma becomes more acidic. "The physical properties of ultra . These properties can be used to identify a substance or to predict how it will behave. Magma can cool to form an igneous rock either on the surface of the Earth - in which case . _____ 1. 4.3.
