مجموعه دگرگونی – آذرین شترکوه به سن پروتروزوئیک­پایانی (548 تا 579 میلیون­سال پیش) واقع در جنوب­شرق شاهرود، طیف متنوعی از پنج گروه ترکیبی متابازیت، متاپلیت، متاگری­وک، متاپسامیت و متاکربنات را شامل می­شود. متاپلیت­های این مجموعه طیف سنگی متنوعی از فیلیت تا گنیس و میگماتیت را شامل می­شوند. شدت دگرگونی در بالاترین درجه، تا مرز ذوب­بخشی و تشکیل گدازه­های گرانیتی پیش­رفته است. نتایج دما - فشارسنجی بر شبه­پهنه­ها دمای (457 تا 641 درجه سانتیگراد و فشار 6 تا 13 کیلوبار) با شرایط دما - فشار رخساره­های شیست­سبز تا آمفیبولیت همخوانی دارد. یافته­های­جدید نشان می­دهد که دنباله­های رسوبی اولیه (سنگ­های ­مادر مجموعه دگرگونی شترکوه) طی یک نظام کششی – کافتی درون قاره­ای و در حوضه­های دریایی - اقیانوسی تشکیل شده­اند. این حوضه­ها، طی رخداد کوهزایی کادومین بسته­شده، سنگ­های آنها دگرگون­شده­ و سپس به صورت آمیزه­های زمین­ساختی یا منشورهای به­هم افزوده، بر پوسته­های قاره­ای سرزمین­های مجاور خود رانده شده­اند.
