Metavolcanic rock in the context of "Volcanic rocks"

Volcanic rocks (often shortened to volcanics in scientific contexts) are rocks formed from lava erupted from a volcano. Like all rock types, the concept of volcanic rock is artificial, and in nature volcanic rocks grade into hypabyssal and metamorphic rocks and constitute an important element of some sediments and sedimentary rocks. For these reasons, in geology, volcanics and shallow hypabyssal rocks are not always treated as distinct. In the context of Precambrian shield geology, the term "volcanic" is often applied to what are strictly metavolcanic rocks. Volcanic rocks and sediment that form from magma erupted into the air are called "pyroclastics," and these are also technically sedimentary rocks.

Volcanic rocks are among the most common rock types on Earth's surface, particularly in the oceans. On land, they are very common at plate boundaries and in flood basalt provinces. It has been estimated that volcanic rocks cover about 8% of the Earth's current land surface.

White Mountain Peak (or simply White Mountain), at 14,252 feet (4,344 m), is the highest peak in the White Mountains of California, the highest peak in Mono County, and the third highest peak in the state after Mount Whitney and Mount Williamson. In spite of its name, the summit block of the peak has large swaths of very dark and colorful orange scree and rock; it is composed of Mesozoic metavolcanic rock, which is igneous rock altered by rising granite.

It is the fourteenth most topographically prominent peak in the contiguous United States. White Mountain Peak is one of only two fourteeners (peaks above 14,000 feet) in California that are not in the Sierra Nevada, the other being Mount Shasta at the far northern end of the state in the Cascade Range. It is the only fourteener in the contiguous United States that is not in the Rocky Mountains, the Cascade Range, or the Sierra Nevada. It is in the Inyo-White Mountains.
