چکیده

در این پژوهش، 9 قطعه از نمونه‌های شهاب سنگی در مجموع به جرم 3590 گرم بررسی شدند که در خبرنامه جهانی ثبت شهاب‌سنگ‌ها درج و رده‌بندی نشده‌اند. برای رده‌بندی این نمونه‌ها، پس از تهیه مقاطع میکروسکوپی و انجام سنگ­نگاری دقیق، برپایه داده‌های زمین شیمیایی ترکیبات عناصر اصلی و کمیاب سنگ کل برآمده از طیف سنجی­های فلئورسانس پرتوی ایکس (XRF) و جرمی پلاسمای جفت شده القایی (ICPMS) در نخست نمونه‌های با ویژگی­های کامل شهاب سنگ‌ها تفکیک گردیده و سپس براساس یافته­های سنگ­نگاری و زمین­شیمیایی رده‌بندی شدند. نتایج بدست آمده نشان می‌دهد که این قطعه­های شهاب‌سنگی دسته شهاب‌سنگ‌های کندریتی، نوع سنگ­شناسی H4 هستند و از نظر ویژگی­های ثانویه چون دگرگونی و هوازدگی فضایی نیز در گروه شهاب‌سنگ‌های دارای هوازدگی و دگرگونی S2  و W2 قرار دارند.

چکیده [English]

In this study, meteorite pieces, with total weight of 259 grams, have been studied which is not listed in the world bulletin of meteorites. In order to classify these samples, after preparing microscopic thin sections and performing accurate petrography, using geochemical data of the major elements and trace elements of whole rock, obtained from XRF and ICPMS methods in Zarazma company’s laboratory, have been studiied. At first, the samples which have properties of meteorites are completely separated and other samples and classified according to common petrographic and geochemical methods. As a result, all of the nine of selected meteorite samples belong to the category of chondrite meteorites with petrological type H4. Also, in terms of secondary characteristics, such as special metamorphism and space weathering, the samples have been studied, in addition they are in the group of meteorites with S2 and W2 level of weathering and metamorphism.
