Igneous rocks are geologically important because their minerals give information about composition of the mantle or the Earth’s crust, from which they are extracted and the temperature and pressure conditions that allowed this extraction, also the history of their ages can be obtained from various forms of radiometric dating which can be compared to the available geological strata, hence knowing the time sequence of events. In some cases, the Igneous Rocks host important mineral deposits for various minerals and metals. You can also compare rocks from Metamorphic Rocks and Fossil Rocks. All types of Igneous Rocks+ have a variety of uses and many unknown and interesting facts. Get more information about main rocks like Granite, Obsidian, Basalt, Diorite, Gabbro.
