چکیده:   (3224 مشاهده)
افیولیت انارک به سن دیرینه زیستی با روند شرقی - غربی در شمال شهر انارک واقع است. علاوه بر گابروهای موجود در توالی افیولیتی انارک، توده­هایی از گابروهای دگرنهاد شده به شکل استوک و دایک درون افیولیت انارک نفوذ کرده­اند. گابروهای دگرنهاد شده جوانتر از افیولیت انارک و قدیمی­تر از مجموعه دگرگونی انارک بوده و دربردارنده کانی­های دیوپسید و اوژیت، هورنبلند اکتبنولیتی، اکتینولیت، ترمولیت، فلوگوپیت، آلبیت و الیگوکلاز، پیکنوکلریت و پنینیت، اپیدوت، گارنت، اسفن، آپاتیت، پرهنیت، کلسیت و کانی­های کدر هستند. نفوذ آب دریا تا پوسته زیرین و گوشته بالایی باعث دگرنهادی دمای بالای گابروها شده است. ناهنجاری مثبت Pb و ناهنجاری منفی Ti, Nb, Ta در شیمی سنگ کل و کلینوپیروکسن و آمفیبول نشانگر محیط زمین­ساختی قوس آتشفشانی وابسته به مناطق فرورانش است. دمای تبلور دیوپسید 1150 تا 1200، فلوگوپیت 750، هورنبلند اکتینولیتی. 600، کلریت 360-540 و اکتینولیت 450 درجه سانتیگراد است.
