چکیده

           گروه شمشک در منطقه بلده دارای گسترش و رخنمون بسیار خوبی می‌باشد. تعداد 22 گونه ماکروفسیل گیاهی متعلق به 14 جنس از راسته‌های مختلفی نظیر اکوئی ستال‌ها، فیلیکال‌ها، بنتیتال‌ها، سیکادال‌ها، گینکگوآل‌ها، چکانوسکیال‌ها و کونی فرال‌ها تشخیص داده شد. دو بیوزون تجمعی (Assemblage zone) در منطقه بلده، البرز مرکزی مورد شناسایی قرار گرفت. بیوزون تجمعی I با دو گونه Ptilophyllum minor و Klukia exilis و بیوزون تجمعی II با اولین حضور گونه Coniopteris hymenophylloides و آخرین حضور گونه Ptilophyllum harrisianum تعیین می‌شوند. همچنین، بر مبنای حضور گونه‌های Equisetites columnaris ، Coniopteris hymenophylloides ، Klukia exilis ، Nilssonia macrophylla و Ptilophyllum minor سن ژوراسیک زیرین تا میانی (؟هتانژین- توآرسین تا باژوسین) برای رسوبات این منطقه خاطرنشان می‌گردد.

چکیده [English]

The Shemshak Group is well-exposed and spread in the Baladeh area (Central Alborz). 22 macrofossil species allocated into 14 genera of various orders such as Equisetales, Filicales, Bennettitales, Cycadales, Ginkgoales, Czekanowskiales and Coniferales are identified. Two asseblage biozones are recognized. Assemblage zone I is established based on Ptilophyllum minor and Klukia exilis, and assemblage zone II is recognized according to Coniopteris hymenophylloides and Ptilophyllum harrisianum. Furthermore, on the basis of presence of index fossils such as Equisetites columnaris, Coniopteris hymenophylloides, Klukia exilis, Nilssonia macrophylla and Ptilophyllum minor the Early to Middle Jurassic age (?Hettangian-Toarcian to Bajocian) is suggested for these sediments.
