Thermoluminescence of ZrSiO 4 ( zircon ) : A new dating method ?
Zircon appears to be a suitable medium for thermoluminescence (TL) dating of sediments from the Quaternary. TL of zircon results predominantly from internal irradiation, due to the relatively high internal concentrations of a-emitting U and Th. The internal dose predominates over the external one that is caused by the surrounding geological layers and cosmic rays. Measurement of the TL buildup ...
متن کاملDating of Precambrian Metasedimentary Rocks and Timing of their Metamorphism in the Soursat Metamorphic Complex (NW IRAN): Using LA–ICP-MS, U–Pb Dating of Zircon and Monazite
Soursat Metamorphic Complex (SMC) in west of Takab city is one of the polyphase metamorphic terrenes in northern Sanandaj-Sirjan metamorphic belt of Iran. The SMC composed mainly of metasedimentary rocks associated with granitic intrusions. Based on metamorphic rocks, two metamorphic phases could be separate in the complex. M1 is representative of regional metamorphisms which varies from greens...

مطالعات قبلی بازار بیمه را به صورت کلی در نظر می گرفتند اما در این مطالعه صنعت بیمه به عنوان متغیر مستفل به بیمه های زندگی و غیر زندگی شکسته شده و هم چنین بیمه های زندگی به رشته های مختلف بیمه ای که در بازار بیمه ایران سهم قابل توجهی دارند تقسیم میشود. با استفاده از روشهای اقتصاد سنجی داده های برای دوره های 48-89 از مراکز ملی داده جمع آوری شد سپس با تخمین مدل خود بازگشتی برداری همراه با تعدادی ...
15 صفحه اولThe Sungun porphyry magma resource and the 120,000-year difference in age between the main stock and the first dike: New evidence from 87Sr/86Sr, 143Nd/144Nd and Pb, SHRIMP U–Pb zircon dating in NW Iran
The Sungun copper porphyry deposit is hosted by a Tertiary magmatic complex in the Azarbayjan province , northwestern Iran. The Sungan mine in its southern and eastern parts is limited by early Miocene volcanic and by Late Cretaceous limestone rocks in northern and eastern parts respectively . The Sungun deposit is associated with a suite of porphyritic granitoids and late dikes intrudi...
