What are pyroxenes?
Q: What are pyroxenes?
A: Pyroxenes are a group of important rock-forming inosilicate minerals found in many igneous and metamorphic rocks.
Q: What is the structure of pyroxenes?
A: Pyroxenes share a common structure consisting of single chains of silica crystals with the general formula XY(Si,Al)2O6, where X and Y represent metal ions.
Q: What is the general formula for pyroxenes?
A: The general formula for pyroxenes is XY(Si,Al)2O6, where X and Y represent metal ions.
Q: Can aluminium substitute for silicon in pyroxenes?
A: Aluminium can substitute for silicon in silicates such as feldspars and amphiboles, but the substitution occurs only to a limited extent in most pyroxenes.
Q: What is pyroxenite?
A: Pyroxenite is an igneous rock made up of minerals from the pyroxene group.
Q: Are pyroxenes only found in igneous rocks?
A: No, pyroxenes are found in both igneous and metamorphic rocks.
Q: What is the chemical makeup of pyroxene?
A: The chemical makeup of pyroxene is XY(Si,Al)2O6, where X and Y represent metal ions.
