چکیده

به‌منظور بررسی گروههای ماسرالی زغا‌ل‌سنگ ناحیه زغال‌دار قشلاق، از 11 لایه زغال‌سنگی متعلق به چهار معدن در حال استخراج شامل: معدنهای زمستان یورت، نرگس‌چال، چشمه‌ساران و شرق کلات، نمونه‌برداری انجام شد. بررسی پتروگرافی آلی زغال‌سنگهای قشلاق، بیانگر حضور هر سه گروه ماسرالی است. گروه ویترینیت (vol% 66/2 – 87/2) شامل:ماسرال های کالودترینیت، کالوتلینیت و کورپوژلینیت، گروه اینرتینیت ( vol% 4/9 – 23/2) شامل: ماسرال‌های فوزینیت، سمی فوزینیت، ماکرینیت، اسکرتینیت، فانگینیت، اینرتودترینیت و میکرینیت و گروه لیپتینیت (vol% 0 – 3/5) شامل: ماسرال‌های اسپورنیت، کوتینیت، رزینیت و لیپتودترینیت هستند. گروه ویترینیت دارای بیشترین و گروه لیپتینیت دارای کمترین فراوانی در این زغال‌سنگها هستند. مقدار مواد معدنی این لایه‌های زغال‌سنگی در محدوده بین 5 و vol% 24/9 متغیر است.
