چکیده

این پژوهش به بیان نتایج تحلیل ساختاری و ریز ساختاری منطقه فریادون واقع در شمال خاور استان فارس پرداخته است. در این پژوهش، یک کمربند با روند شمال باختری – جنوب خاوری در بخش مرکزی پس بوم زاگرس و در شمال خاور پهنه دگرگونی سنندج – سیرجان معرفی گردیده است. وضعیت میانگین برگ وارگی و خط وارگی در این کمربند جدید به ترتیب 315˚,57˚NE و 116˚ ,23˚ می باشد. مطالعه نشان گرهای جنبش شناختی رخداد برش دگرشکلی، چپ گرد و به سمت شمال باختر را در این کمربند نشان می دهد که بر خلاف دگرشکلی راست گرد شناخته شده در نواحی مرکزی پهنه دگرگونی سنندج – سیرجان است.
