چکیده

مجموعه نفوذی ندوشن بخشی از فعالیت نفوذی ترشیری است که در بخش مرکزی پهنه ماگمایی ارومیه- دختر قرار گرفته است. این مجموعه مرکب از چهار توده اصلی با ترکیب دیوریتی، گرانیت- گرانودیوریتی، دیوریت پورفیری و گرانودیوریتی است. در همه بخشهای تودههای دیوریت پورفیری و گرانودیوریتی و بخشهایی از تودههای گرانیت- گرانودیوریتی حضور انکلاو های میکروگرانولار مافیک با ترکیب دیوریت، مونزودیوریت و کمتر گابرو- دیوریت به شکل آشکاری خودنمایی می کند. از دید ویژگیهای ژئوشیمیایی، این مجموعه نفوذی متاآلومین تا کمی پرآلومین، نوع I و متعلق به سری کالک آلکالن با پتاسیم متوسط تا بالاست. بررسی های ژئوشیمیایی نشاندهنده نقش کلیدی آلایش و آمیختگی، در تحول و تکوین ماگماهای توده های یاد شده و تشکیل انکلاوهای میکروگرانولار مافیک است. با استفاده از سنسنجی U-Pb زیرکن، سنهای تقریبی 30 میلیون سال برای توده های دیوریتی و گرانیت- گرانودیوریتی و 24 میلیون سال برای توده های دیوریت پورفیری و 25 میلیون سال برای توده های گرانودیوریتی بهدست آمده است. افزون بر آن، برای گستره ای کوچک از واحد گرانیت- گرانودیوریتی که در گوشه شمال خاوری منطقه، در شمال گسل دهشیر و در حاشیه باختری پهنه ایران مرکزی جای گرفته است؛ سن تقریبی 40 میلیون سال به دست آمد. شواهد ژئوشیمیایی نشان میدهد که ماگمای توده های مورد مطالعه، حاصل ذوب بخشی پوسته قاره ای تحت تأثیر مذابهای گوشتهای، در محیط حاشیه فعال قارهای است و به نظر می رسد که ذوب سنگ هایی با ترکیب متابازالتی و متاگری وکی در پوسته زیرین در تعادل با پسمانده ای شامل کلینوپیروکسن، پلاژیوکلاز و به مقدار کمتر آمفیبول، با ویژگی های ژئوشیمیایی توده های نفوذی مورد مطالعه بیشترین هماهنگی را داشته باشد.

چکیده [English]

The Nodoushan intrusive complex is a part of Cenozoic plutonism, which located in the central part of the Urumieh–Dokhtar Magmatic Belt (UDMB). This complex consists of four main intrusives, including diorite, granite-granodiorite, diorite porphyry and granodiorite. Mafic microgranular enclaves (MMEs) are abundant in the diorite porphyry and granodioritic intrusives and also in some parts of Granitegranodiorite intrusives, which consist of diorite, monzodiorite and rarely gabbro -diorite. According to geochemical data, the Nodoushan intrusive complex is metalominous to moderately peraluminous, I-type and shows medium to high potassium calc-alkaline affinity. Geochemical investigations show that contamination and mafic-felsic magma mixing played significant role in the evolution and petrogenesis of the mentioned intrusions magmas and formation of MMEs. Using U-Pb zircon dating method, the obtained magma crystallization ages are about 30 Ma for the dioritic and granite-granodiorite intrusives, 24 Ma for the diorite porphyry and 25 Ma for the granodioritic intrusives. In addition, the age for part of the granite-granodiorite unit that is located in the northeast corner of the region, at the north of the Nain-Dehshir fault (NDF) and the western part of the Central Iranian Microcontinent (CIM), was determined 40 Ma. The geochemical evidences suggest that the studied intrusions magmas were derived from partial melting of continental crust caused by the mantle melts in an active continental margin. It seems that the melting of rocks with combination of metabasalt and metagraywacke in the lower crust in balance with the residual consisting of clinopyroxene, amphibole and to a lesser extent plagioclase; have the greatest harmony with geochemical characteristics of the studied intrusions.
