چکیده

توده گرانیت- گنایس میلونیتی شمال شرق معدن ژان، جزئی از مجموعه ماگمایی- دگرگونی شمال غرب شهرستان ازنا در استان لرستان و در پهنه ساختاری سنندج- سیرجان واقع شده است. این مجموعه ماگمایی- دگرگونی شامل گرانیت- گنایس ، آمفیبولیت ، مرمر و شیست است. گرانیت‌- گنایس مورد بررسی، دارای بافت اصلی لپیدوگرانوبلاستیک و کانی‌های اصلی کوارتز، آلکالی فلدسپار (میکروکلین پرتیتی)، پلاژیوکلاز، کانی‌های فرعی مسکویت فنژیتی، اپیدوت (ماگمایی)، آلانیت، تورمالین، زیرکن، اسفن و کانی متداول بیوتیت است. این توده گرانیتوئیدی از نظر ژئوشیمیایی پرآلومین تا کمی متاآلومین، کالک آلکالن تا حدودی آلکالن بوده و در موقعیت زمین‌ساختی پس از برخورد در حاشیه فعال قاره واقع شده است. در نمودار SNX در برابر SNY در دو محدوده هم‌زمان با دگرشکلی و مراحل پایانی دگرشکلی هم‌پوشانی دارند و از نوع آلکالن- کلسیک هستند. این توده گرانیتوئیدی دارای ماهیت A-type است و در زیرگروه A2 قرار می‌گیرد.
