Scoria is a pyroclastic, highly vesicular, dark-colored volcanic rock formed by ejection from a volcano as a molten blob and cooled in the air to form discrete grains called clasts. [ 1 ] [ 2 ] It is typically dark in color (brown, black or purplish-red), and basaltic or andesitic in composition.
Hawaii’s signature barbecue style is best exemplified by the state’s most famous dish: kalua pig, which cooks for hours in an underground pit (called an imu) heated with hot volcanic rocks and ...
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 .
In geology, agglutinate is pyroclastic rock consisting of volcanic bombs fused together by volcanic heat. [1] It typically occurs in spatter cones but can also be rafted on lava flows to form mounds. [1] [2]
Trachybasalt is a volcanic rock with a composition between trachyte and basalt. It resembles basalt but has a high content of alkali metal oxides . Minerals in trachybasalt include alkali feldspar , calcic plagioclase , olivine , clinopyroxene and likely very small amounts of leucite or analcime .
The term vug is also used for similar cavities although the meaning of vug is usually restricted to cavities in rocks formed by the removal of material such as soluble minerals. These cavities usually contain layers of various colors (red, pink, gray, etc.) composed by crystals of quartz, [ 1 ] chalcedony , [ 3 ] hematite , fluorite [ 4 ] and ...
These structures are lighter colored than the host rock and typically range in diameter from 0.05mm to over 5 cm. [1] [2] [3] In 1648, Aldrovandi created the term variolite for aphanitic or fine-grained igneous rocks containing varioles. [4] [5] The weathering of varioles often cause variolites to have a pock-marked appearance.
