چکیده

تجزیه و تحلیل ژئوشیمیایی عناصر اصلی 12 نمونه از ماسه­سنگ­ها و شیل­های سازند شیرگشت در دو مقطع کوه ­عاشقان و کوه­ راهدار به سن اردوویسین واقع شده در بلوک کلمرد، ایران­مرکزی و رسم داده­ها بر روی نمودار­های تقسیم­بندی سنگ­های آواری ترکیب آنها را کوارتزآرنایت و شیل نشان می­دهد. همچنین، استفاده از نمودار­های تفکیکی، دوتایی و مثلثی، برخاستگاه کراتون و چرخه دوباره و جایگاه زمین­ساختی حاشیه غیر­فعال قاره­ای را برای این نهشته­ها تداعی می­نماید. داده­های یادشده  پیشنهاد کننده سنگ مادر رسوبی کوارتزی برای ماسه­سنگ­ها و سنگ آذرین متوسط تا اسیدی برای شیل­ها است. افزون برآن، تعیین اثر هوازدگی در ناحیه منشأ با استفاده از اندیس CIA، میزان هوازدگی این نهشته­ها را در منطقه منشأ شدید معرفی می­کند. این موضوع می­تواند به وسیله آب و هوای گرم و مرطوب در ناحیه منشأ از حاشیه قاره‌ای غیرفعال شرح داده شود.
