Exempel på hur du använder SCORIA i en mening

• If the magma contains abundant volatile components which are released as free gas, then it may cool with large or small vesicles (bubble-shaped cavities) such as in pumice, scoria, or vesicular basalt.
• On that first day, the volcano had begun strombolian pyroclastic activity; and within 24 hours there was a scoria cone fifty meters high, created by the ejection of lapilli fragments up to the size of a walnut and larger, semi-molten volcanic bombs.
• Most of them are cinder cones and scoria cones, but there are also some lava domes and about 20 tuff rings near the coast and offshore, which were formed by underwater phreatic eruptions.
• To the southeast of Maungawhau / Mount Eden was Te Pou Hawaiki, a small scoria cone located at the modern-day site of the Auckland College of Education, which was quarried away.
• The broader Oku or Foumbot volcanic field also includes many scoria cones and maars, several of which are filled by crater lakes.
• Andesite magma in effusive eruptions cools to form dark grey lava if gas-poor or scoria if gas-rich.
• The volcanoes consist mainly of basalt, trachyte and phonolite in the form of lava flows, scoria and hydrovolcanic formations.
• They consist of lava flows, maars, scoria cones and tuff rings, with volumes reaching , and were emplaced between 600,000 and 150,000 years ago.
• Sillar facies Orvieto-Bagnoregio Ignimbrite (black blocks of scoria in red tuff) occurs at Civita di Bagnoregio in the Vulsini volcanic district of central Italy.
• The Parade is flanked by Victorian blue gum eucalyptus trees on gently sloping banks either side of the three-lane, one-way roads centred by a wide parade ground topped with granulated rock (similar to scoria), with planted boxes of a low bush called Hebe.
• The summit cone is formed by lapilli, pyroclastics and scoria, one half has a white colour and the other half is black; some areas are white from fumarolic alteration.
• Following the caldera collapse, lavas were erupted from the northern part of the island and the caldera-rim fissure zone, scoria and lavas from the caldera-wall fissure zones, pyroclastics and lavas from intracaldera cones, and recent pyroclastic fall deposits on the outer cone.
• Erosion has destroyed the original summit of the mountain, along with its southeastern slope and much of the volcano's interior, revealing purple, red, and black scoria layers that alternate with yellow, brown, and orange pumice and tuffs, along with white pumice interbedded in a matrix with black lava fragments.
• Thick basalt and andesite lava flows and scoria agglomerates were produced from early effusive and strombolian eruptions over a long period of time.
• Thus Panmure Basin is no different from a number of other volcanoes in the Auckland volcanic field, such as the Auckland Domain Volcano, Māngere Lagoon Volcano, Waitomokia, Te Tatua-a-Riukiuta and Crater Hill (each with one or more scoria cones inside their explosion crater), except that Panmure Basin's small central scoria cone was buried.
• Crater rows with spatter, scoria and some tuff cones, lava shields, tindars and hyaloclastite hills.
• The second stage produced a large hyaloclastite scoria mound erupted beneath the Cordilleran Ice Sheet during the Pleistocene.
• It consists of a main cone made of pyroclastic material including palagonitized rock along with basaltic andesite cinders and glassy scoria, as well as thin layers of basaltic andesite lava flows.
• The particles from lava fountains usually cool in the air before hitting the ground, resulting in the accumulation of cindery scoria fragments; when the air is especially thick with clasts, they cannot cool off fast enough due to the surrounding heat, and hit the ground still hot, the accumulation of which forms spatter cones.
• It features over 70 Pleistocene or Holocene stratovolcanoes, as well as calderas, maars and scoria cones.
