امام جمعه امیر، جهانگیری احمد، مؤذن محسن. بررسی زمین شیمی و جایگاه زمین‌ساختی ماگمایی توده‌های نفوذی میزبان فیروزه در معدن فیروزه- طلای دامغان (باغو)، کمان آتشفشانی-نفوذی ترود-چاه شیرین. مجله بلورشناسی و کانی شناسی ایران. 1400; 29 (1) :63-80

چکیده: (1233 مشاهده)
توده‌های نفوذی نیمه‌عمیق دیوریتی و گرانودیوریتی به سن ائوسن میانی و توده‌های گنبدی شکل ریولیتی در غرب کمان آتشفشانی-نفوذی ترود-چاه شیرین، سنگ‌های آتشفشانی ائوسن پیشین را قطع کردهاند. توده‌های گرانودیوریتی و ریولیتی میزبان اصلی کانهسازی فیروزه و طلا در معدن دامغان (باغو) هستند. این توده‌ها سرشت آهکی-قلیایی غنی از پتاسیم، متاآلومین (دیوریتها و بخشی از گرانودیوریتها) تا پرآلومینوس (ریولیتها و بخشی از گرانودیوریتها) دارند. مقایسه مقادیر TiO2-La-Hf و Zr-Nb-Ce/P2O5 و همچنین نسبتهای Rb به Y+Nb نشان دهنده ارتباط فعالیت ماگمایی با محیطهای پس برخوردی تتیس جوان است. از طرفی دگرنهادی گوشته زیر کمان در اثر آزاد شدن سیالها از رسوبها و ورقه فرورونده سبب ناهنجاری منفی عناصر Ti، Nb و Ta و نسبت بالای عناصر سنگ دوست بزرگ یون به عناصر با شدت میدان بالا (LILE / HFSE) در گوشته و ماگمای برآمده شده است. ذوببخشی گوشته سبب تشکیل ماگمای اولیهای شده که در اثر جدایش بلوری، آلایش پوسته‌ای و آمیختگی، ماگماهای دیوریتی، گرانودیوریتی و ریولیتی را بوجود آورده است.
واژه‌های کلیدی: گرانودیوریت، پس برخوردی، باغو، دامغان، فیروزه.
