In February and March 2022, a large amount of pumice stone appeared along the shoreline Thailand. Pumice is type extrusive volcanic rock, since there are no volcanoes in Gulf Thailand, an interesting question was where stones originated from. Another whether could be vehicle for microplastics (MPs) which then journey across ocean until reaching coast A preliminary study begun, randomly collecte...

The wide cause of death that occurs in the world is due to cancer and efficient tool diagnose microarray. essential step determine depends on selecting significant genes from dataset. This paper proposes a framework utilizing two levels selected for classifying leukemia cancer. An openly accessible microarray dataset comprising 7,129 72 patients employed this research. first level gene selectio...

By using recently determined experimental phase equilibria we show that the viscosity of granitic magmas emplaced atupper crustal levels is approximately constant a -• 104.5 Pa s, irrespective of their temperature and level of emplacement. Magmas crystallizing as granitic plutons are not water-poor and thus not more viscous than their extrusive equivalents. Instead, comparison between pre-erupt...

Abstract In the Lac de Gras (LDG) kimberlite field, Northwest Territories, Canada, coherent kimberlites (CKs) occur as tabular dykes, pipe-shaped diatremes, and irregular bodies without well-defined geometries. Combining morphology of CK with occurrence fragmented olivine microcrysts allows distinction four types at LDG: (1) dykes no broken olivine; (2) but probable sheet geometry (3) pipe-fill...

Volcanic cinder, also known as scoria, is an extrusive igneous rock that forms when gas-rich magmas of basaltic or andesitic composition cool quickly. It typically dark in color, ranging from black to red depending on its chemical composition. Sometimes fresh cinder samples show a variety shiny metallic colors surface blue gold silver. The origin these has remained unknown up now. Cinder erupti...

Abstract Late brittle extension is a common feature in orogenic belts, and its role mountain building processes still the subject of debate. Its timing relationship with crustal thickening, topography, basin infill, rock exhumation are key importance determining whether it major factor development or merely causes near-surface secondary effects. We examined this question relation to active arc-...

in the central iranianvolcanic belt (civb), north-west of shahre-babak, in the area of javazm, dehaj and khabr, about 60 subvolcanic porphyritic dacitic to rhyodacitic domes (1-10 km2) are intruded into a variety of rock sequences from mesozoic to early miocene in age. these rocks are a part of dehaj-sardoieh belt. the civb contains intrusive and extrusive rocks of cretaceous-quaternary age. ge...

(1) Background: The widely developed thrust structures in the Jingzhushan Formation of late Cretaceous Nyima Basin are related to collision which leads orogeny between Lhasa and Qiangtang blocks. Clarifying tectonic properties is great significance characterize evolution block block. (2) Methods: Combined with mineralogy petrology U-Pb zircon dating extrusive rocks, a detailed magnetic fabric t...
