What are Volcanic Rocks? | VolcanoDiscovery
Volcanic rocks often have a vesicular texture, which is the result voids left by volatiles escaping from the molten lava. Pumice is a rock, which is an example of explosive volcanic eruption. It is so vesicular that it floats in water. Pyroclastic rocks are the product of explosive volcanism. They are usually felsic (high in silica).

Volcanic Rocks: Examples & Uses – Geology In
Volcanic rocks, also known as lava rocks, are a diverse group of igneous rocks formed when magma or lava solidifies during volcanic eruptions. Their formation begins deep beneath the Earth's surface, where magma is generated. Tectonic forces then push this magma upward through the crust, leading to its eventual cooling and solidification.

The Life of Volcanic Rocks During and After an Eruption
Volcanoes are constantly growing and changing. Every time a volcanic eruption occurs, new rock is added to the surrounding area. These eruptions play a big part in the formation and destruction of rocks as well as in shaping the Earth's surface. Yet, we do not know everything about the histories of the volcanoes that previously existed on Earth. …

Extrusive rock | Igneous, Volcanic, Magma | Britannica
extrusive rock, any rock derived from magma (molten silicate material) that was poured out or ejected at Earth's surface. By contrast, intrusive rocks are formed from magma that was forced into older rocks at depth within Earth's crust; the molten material then slowly solidifies below Earth's surface, where it may later be exposed through erosion.

3.6: Igneous Rocks
Volcanic Rocks. Let us start with textures associated with rocks formed by lava flows. Magmas that erupt as lava onto the earth's surface cool and solidify rapidly. Rapid cooling results in an aphanitic igneous texture, in which few or none of the individual minerals are big enough to see with the naked eye. This is sometimes referred to as a ...

Volcanic Rock
Volcanic rocks are developed in most of the petroliferous basins in China with relatively widespread distributions and large thicknesses. The reservoirs were formed by three processes: volcanism, diagenesis, and tectonics. Based on their origins, volcanic reservoirs can be divided into four types: lava, pyroclastic, dissolved, and fractured reservoirs (Table 15.9).
