بررسی کانی شناسی و شیمی کانیها در سنگهای آندزیتی و مقایسه آن با میانبارهای ماگمایی درون آنها در منطقه قخلار (آذربایجان شرقی)
The Ghikhlar area is located at the NW Marand town, East Azarbaidjan. The wide range of Plio-Quaternary volcanic activites with volcanic and associated volcano-clastic rocks having compositions mainly as andesite to silica-undersaturated rocks (leucite basanite, leucite-tephrite and tephrite) have been covered mostly the rock units prior to the Cenozoic. The phenocrysts in andesites are amphibo...
متن کاملNothofagus dieback on Mt. Giluwe, Papua New Guinea!
The phenomenon of patch dieback in stands of Nothofagus on Mt. Giluwe, in the southern highlands of Papua New Guinea, is described. Ecological studies that have been carried out are reviewed. Based upon the results of surveys on Mt. Giluwe, the role of Phytophthora cinnamomi in contributing to the dieback is examined. A comparison is made of Nothofagus dieback on Mt. Giluwe with Metrosideros di...
متن کاملThe Origin of Co-Magmatic Andesite Enclaves in the Rabor Miocene Pyroxene Andesites, SE Kerman, Iran: Insights from Textural and Mineralogical Composition
The Miocene pyroxene andesite lava flows are exposed in southeastern edge of Urumieh Dokhtar Magmatic assemblage in Iran. The hypocrystalline andesite in parts contain conspicuous co-magmatic igneous enclaves which are dark grey and occur mostly as spherical and occasionally as ribbon shapes with some showing chilled margins. Petrographic study shows that the ribbon type enclaves have been form...
متن کاملMalaria in Papua New Guinea. Implications for the British Army.
Malaria poses the greatest health threat to British soldiers engaged in jungle training in Papua New Guinea. This paper provides detailed epidemiological information gained following a visit to the Papua New Guinea Malaria Research Unit in January 1986.
متن کاملHigh-Mg# andesitic lavas of the Shisheisky Complex, Northern Kamchatka: implications for primitive calc-alkaline magmatism
Primitive arc magmatism and mantle wedge processes are investigated through a petrologic and geochemical study of high-Mg# (Mg/Mg ? Fe [ 0.65) basalts, basaltic andesites and andesites from the Kurile-Kamchatka subduction system. Primitive andesitic samples are from the Shisheisky Complex, a field of Quaternary-age, monogenetic cones located in the Aleutian–Kamchatka junction, north of Shiveluc...
