چکیده

کانی‌سازی مس اپی‌ترمال در منطقه مأمونیه به صورت رگه/ رگچه‌های سیلیسی- سولفیدی- اکسیدی رخ‌داده است که توسط توده ­های نفوذی مونزونیتی، گابرویی و سنگ­ های آتشفشانی با ترکیب آندزیتی میزبانی می‌شود. مگنتیت و تیتانومگنتیت از مهم‌ترین کانه‌های اکسیدی هیپوژن در این منطقه هستند که در توده‌های نفوذی به صورت تیتانومگنتیت و در رگه‌های سیلیسی اغلب به صورت مگنتیت حضور دارند. ترکیب شیمیایی آنها در سامانهFeO-Fe₂O₃-TiO₂  نشان‌دهنده تمایل به سمت وستیت (FeO) است. محتوای افزایشی Al₂O₃  و TiO₂ در مگنتیت‌های رگه‌های سیلیسی نسبت به توده مونزونیتی از ویژگی‌های مگنتیت‌های گرمابی است. کاهش محتوای Cr₂O₃ و V₂O₃ در مگنتیت‌های تعادل مجدد یافته رگه‌های سیلیسی بیانگر تشکیل آنها در فوگاسیته اکسیژن بالاتری نسبت به تیتانومگنتیت‌های ماگمایی مونزونیتی است. نمودار Al+Mn در برابر Ti+V نشان می‌دهد که تیتانومگنتیت‌های توده نفوذی در دمای بالای 500 درجه و مگنتیت‌های رگه‌های سیلیسی در دمای 200 تا300 درجه سانتی‌گراد تشکیل شده‌اند. کاهش دمای سامانه تحت‌تأثیر اختلاط سیالات سرد حین نفوذ سیالات گرمابی به نهشته‌شدن مگنتیت همراه رگه ­های سیلیسی در دمایی پایین­تر منجر‌شده است. نمودار Ti در برابر Mg+Al+Si  نشان‌دهنده تبلور تیتانومگنتیت‌های ماگمایی در شرایط عدم واکنش گسترده سیال گرمابی و سنگ دیواره است. افزایش فوگاسیته اکسیژن از ماگمای والد به سمت رگه‌های کانی‌سازی مشاهده می‌شود و مگنتیت‌های توده نفوذی در دمای بالا و ƒO₂ پایین­تری تشکیل شده ­اند.
