چکیده
رفتار سنگ‌های مختلف در مقابل فرسایش متفاوت بوده و این اختلاف به ویژگی‌های ذاتی و محیطی سنگ‌ها بستگی دارد. به‌عبارتی دیگر، بعضی از واحدهای سنگ‌شناسی حساس به فرسایش و مستعد تولید رسوب هستند. در همین راستا، مطالعه حاضر، با هدف بررسی حساسیت به فرسایش و مقاومت سنگ‌های سازندهای گروه فارس (آهک میشان، ماسه‌سنگ آغاجاری و انیدریت گچساران) و سازند آسماری با استفاده از روش سلبی در مناطق بهبهان، گچساران، دیلم و دهدشت انجام شد. نتایج مقایسه میانگین 81 نمونه از چهار نوع سنگ نشان داد که در سطح معنی‌داری 0.05 درصد و با نتایج حاصل از تحلیل واریانس ANOVA بین سنگ‌های مورد مطالعه اختلاف معنی‌داری وجود دارد. به‌طور کلی، سنگ آهک آسماری با میانگین امتیاز روش سلبی بین 70.99-66.72 مقاوم‌ترین سنگ و در ادامه رتبه‌بندی از نظر مقاومت به فرسایش به‌ترتیب سنگ آهک میشان، سنگ آهک آغاجاری و انیدریت گچساران قرار می‌گیرند.

چکیده [English]
Rock behavior varies with different erosions, which depends on the inherent and environmental characteristics of the rock. In other words, some petrological units are susceptible to erosion and have sediment production potential. This study is conducted to investigate the sensitivity to erosion and resistance of rock formations of Fars group (Mishan limestone, Aghajari sandstone and Gachsaran Anhydrite) and Asmari formation using Selby method in Behbahan, Gachsaran, Deylam and Dehdasht areas. Results of analysis of ANOVA variance based on the comparison of 81 samples from 4 types of rocks showed that there was a significant difference between the rocks (p= 0.05).In general, the Asmari limestone with scoring mean of 66.72-70.99 is the most rock resistant based on theSelby method. Mishan, Aghajari limestone, Gachsaran Anhydrite will be in the next ranks, respectively.
