چکیده

گارنت و تورمالین، از جمله کانی‌های فرعی موجود در لوکوگرانیتهای مرزیان واقع در شمال ازنا، بخشی از پهنه‌ زمین‌ساختی سنندج-سیرجان می‌باشند. این لوکوگرانیت ها در سنگ‌های دگرگونی، شامل میکاشیست و آندالوزیت شیست رخنمون دارند. گارنت‌ها اکثرا بی‌شکل تا نیمه شکل‌دار، بدون حاشیه واکنشی و ادخال، دارای ‌ترکیب یکنواخت و غنی از اسپسارتین می‌باشند. طبق ‌شواهد پتروگرافی و شیمی کانی گارنت‌ها دارای منشأ ماگمایی و مشتق‌ شده از مذاب‌های فلسیک بوده و با توجه به مقدار CaO<4wt% پایین و مقادیر متغیری از MnO می‌باشند، بر این اساس گارنت‌های مورد بحث در یک ماگمای نوع S و شدیداً پرآلومینه و تحت فشار کم در پوسته بالایی متبلور شده و نظر به محتوایCaO کمتر از 4 درصد و MnO بالا درصد، دارای خاستگاه متاپلیتی است. تورمالین‌ها اغلب بی‌شکل تا نیمه شکل‌دار در ابعاد متوسط تا درشت و دارای ترکیب شورلیت-دراویت بوده و در گروه قلیایی قرار‌می‌گیرند. تورمالین‌ها (شورلیت و دراویت) به دو گروه ماگمایی با نسبت بالای Fe/Fe+Mg و Al و هیدروترمالی با Fe# پایین رده‌بندی می‌شود. بررسی شیمی کانی‌های گارنت و تورمالین دلالت بر S تایپ بودن ماگمای گرانیت مرزیان دارد.
