Igneous Rocks Introduction Youtube This is a brief introduction to igneous rocks and how to identify them in a hand specimen. rock types included are peridotite, basalt, andesite, granite, pe. Here’s a basic overview of the classification: 1. intrusive (plutonic) igneous rocks: these rocks form from magma that cools and solidifies beneath the earth’s surface. the slower cooling rate allows for the growth of visible mineral crystals. intrusive rocks tend to have a coarse grained texture. Pumice is a light colored, extremely porous igneous rock that forms during explosive volcanic eruptions. it is used as aggregate in lightweight concrete, as landscaping aggregate, and as an abrasive in a variety of industrial and consumer products. (geology ) figure 6. Igneous rocks (fiery rocks) are made when molten material inside or outside the earth cools and becomes solid. this melted rock is called magma when it is inside the earth. when magma finds its way to the surface through cracks or volcanoes, it is called lava. when lava cools on top of the earth’s surface, it forms extrusive, or volcanic.

Long, extremely thin volcanic glass. rock texture with large crystals that are visible to the naked eye. term used to describe intrusive igneous rock. igneous rocks are one of three main types of rocks (along with sedimentary and metamorphic), and they include both intrusive and extrusive rocks. Phaneritic: coarse grained texture due to slow cooling (typical of plutonic rocks). granite is a common example of a phaneritic igneous rock. this rock has large, visible crystals of minerals such as quartz, feldspar, and mica. aphanitic: fine grained texture due to rapid cooling (typical of volcanic rocks).
