Floor 1. Igneous rocks solidify from molten rock (called magma within the Earth and lava on the surface). They are identified by mineral content and texture — the size and shape of their mineral grains. Texture is controlled by the rate of cooling: magma that cools slowly deep in the Earth forms rock with large crystals, and lava that cools ...

Igneous rocks are called intrusive or plutonic when they cool and solidify beneath the surface.Because they form within the Earth, cooling occurs slowly.Such slow cooling allows time for large crystals to form, therefore, intrusive or plutonic igneous rocks have relatively large mineral crystals that are easy to see. Granite is the most common intrusive …

There are three main types of rocks: sedimentary, igneous, and metamorphic. Each of these rocks are formed by physical changes—such as melting, cooling, eroding, compacting, or deforming —that are part of the rock cycle.

Basalt is an extrusive igneous rock consisting primarily of plagioclase feldspar and pyroxene minerals. It is fine-grained (aphanitic) and dark in color, often with visible voids formed from gas bubbles. It is the extrusive equivalent of gabbro. Basalt is the most common igneous rock on the Earth's surface.

Larger scale features, such as fractures and layering, are considered rock structures in comparison. There are nine main types of igneous rock textures: Phaneritic, vesicular, aphanitic, porphyritic, poikilitic, glassy, pyroclastic, equigranular, and spinifex. Each kind of texture has a variety of different characteristics that make them unique.

Igneous Rocks. 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, …

The slow cooling process allows crystals to grow large, giving the intrusive igneous rock a coarse-grained or phaneritic texture. The individual crystals in phaneritic texture are readily visible to the unaided eye. Figure 5.1.1 5.1. 1: Basalt is a classic fine-grained (aphanitic) extrusive igneous rock.

Igneous petrology is the study of igneous rocks, which are formed through the solidification of molten material (magma or lava). Igneous rocks are classified based on their mode of formation (intrusive or extrusive) and their mineral composition. Intrusive igneous rocks form when magma cools and solidifies beneath the Earth's surface.

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.

The two best-known igneous rock types are basalt and granite, which have distinctly different compositions and textures. Basalt is the dark, fine-grained stuff of many lava flows and magma intrusions. Its dark minerals are rich in magnesium (Mg) and iron (Fe), hence basalt is called a "mafic" rock.
