dyke swarm การใช้

• The last magmatism identified is the Jersey Dyke Swarm from.
• The Okavango Dyke Swarm overlaps with the Lebombo and Large Igneous Province.
• Intrusion of Okavango Dyke Swarm occurred in two distinct stages.
• Both radial and linear dyke swarm configurations exist.
• Huge dyke swarms are formed in radial geometry.
• Giant dyke swarms having lengths > 300 km are a common record of severely eroded LIPs.
• The Jersey Main Dyke Swarm consists of dolerite dykes intruded into the South East Igneous complex.
• By the time of intrusion of the Florida dyke swarm, Piedra Alta Terrane was experiencing extensional tectonics.
• The number of Jurassic dykes accumulates, hence a giant dyke swarm can be developed in the region.
• The "'Uruguayan dyke swarms "'consist of three groups of tectono-stratigraphic terrane.
• West of Sarand?del Y?Shear Zone the R韔 de la Plata Craton is intruded by the Florida dyke swarm.
• Intrusive events and dyke swarm emplacement in Karoo Large Igneous Province occurred during 183 174 Ma in the Mesozoic era.
• Jurassic dykes found in the dyke swarms are mostly composed of dolerite, containing clinopyroxene, plagioclase, and olivine.
• The flow of magma and structure of rocks at the time of Karoo magmatism can be observed by the orientation of dyke swarm.
• The exact timing is uncertain, but associated folds within the Devonian are cut by members of the Late Carboniferous to Early Permian dyke swarm.
• So magma flowing to Okavango Dyke Swarm is sourced from lateral side from the Karoo Triple junction, rather than an uprising active mantle plume head.
• Despite having some characteristics similar to those of igneous rocks formed near subduction zones, the Florida dyke swarm rocks are unlikely to have formed in such environment.
• Mawenzi forms a horseshoe shaped ridge with pinnacles and ridges opening to the northeast which has a tower like shape resulting from deep erosion and a mafic dyke swarm.
• The linear dyke swarms often have a high proportion of dykes relative to country rocks, particularly when the width of the linear field is less than 100 km.
• The dyke swarm could extend for such a large area because of the pre-existing basement brittle fracture networks, instead of stress formed by the plate movement.
