Abstract

At the same time, with the expansion and flourishing of the ancient site of Shahr-i Sokhta in southeastern Iran in the third millennium BC, many satellite sites formed around it. Population growth, productivity boom, specialization, and the development of this ancient city led its residents to seek habitation in new and separate regions in connection with the main center of the colony; that is, Shahr-i Sokhta, to create these satellite villages around it. Thus, in the second and third periods of Shahr-i Sokhta, various satellite sites around this ancient city appeared. The most important is in the mounds of the Rud-i Biyaban in the second period of settlement in Shahr-i Sokhta. Tepe Sadegh in the southern area of Qale Rostam is one of the most significant satellite sites of the third millennium BC. Its excavations began in 2009 by the Archaeological Committee of Sistan and Baluchestan University. The result of the excavations is the discovery of remarkable and valuable cultural findings, including architectural structures, pottery, stone artifacts, metal artifacts, and statuettes. Valuable discoveries from the excavations of this ancient site indicate the depth of extensive cultural relations of this site with Shahr-i Sokhta and other neighboring historical regions. This research is done based on the data obtained from laboratory studies of buff ware obtained from the Tepe Sadegh by various instrumental methods, including X-ray diffraction (XRD) and X-ray fluorescence (XRF). A comparative study of this experimental study results with the results of the analysis of buff ware samples obtained from Shahr-i Sokhta has indicated that the pottery discovered from both areas has a very similar structure and chemical composition. It suggests that the potters of Shahr-i Sokhta and the surrounding satellite sites, such as the Tepe Sadegh, may have used the same clay deposits to produce their pottery. In addition, laboratory experiments indicate that with the establishment of specialized centers for the production of pottery products in the form of satellite sites around Shahr-i Sokhta, the quality of ceramic products in terms of construction, compared to Shahr-i Sokhta, has improved somewhat.

چکیده: همزمان با گسترش و شکوفایی محوطه باستانی شهر سوخته در جنوبشرق ایران در هزاره سوم قبل از میلاد، در پیرامون آن، محوطه‌های اقماری بسیاری شکل گرفت. افزایش جمعیت، رونق تولیدات و تخصص‌گرایی، همزمان با توسعه این شهر باستانی، موجب شد تا ساکنان آن به دنبال اسکان در مناطق تازه و مجزایی در پیوند با مرکز اصلی این کلنی؛ یعنی شهر سوخته، این روستاهای اقماری را در اطراف آن، ایجاد نمایند. بدین ترتیب، در دوران‌های دوم و سوم شهر سوخته، محوطه‌های اقماری مختلفی در پیرامون این شهر باستانی، پدید آمد که مهمترین آنها در تپه‌های رود بیابان در دوره دوم استقرار در شهر سوخته است. تپه صادق در حوزه جنوب قلعه رستم، یکی از مهمترین این محوطه‌های اقماری در هزاره سوم پیش از میلاد است که کاوش‌های آن از سال ۱۳۸۸ هجری شمسی، توسط هیأت باستان‌شناسی دانشگاه سیستان و بلوچستان آغاز شد که دستاورد آن، کشف یافته‌های فرهنگی بسیار مهم و با ارزشی، شامل: ساختارهای معماری، سفال، اشیای سنگی، اشیای فلزی، پیکرک‌ها و غیره است. کشفیات ارزشمند حاصل از کاوش‌های این محوطه باستانی، حاکی از عمق ارتباطات گسترده فرهنگی این محوطه با شهر سوخته و سایر مناطق تاریخی همجوار است. در این پژوهش که مبتنی بر داده‌های حاصل از بررسی‌های آزمایشگاهی سفالینه‌های نخودی به‌دست‌آمده از تپه صادق به روش‌های مختلف دستگاهی، اعم از : پراش پرتوی ایکس (XRD) و فلورسانس اشعه ایکس (XRF) است؛ مقایسه تطبیقی نتایج حاصل از این پژوهش تجربی با نتایج آنالیز نمونه‌های سفال نخودی به‌دست‌آمده از شهر سوخته، نشان داده است که سفال‌های مکشوفه از هر دو منطقه، دارای ساختار و ترکیب شیمیایی بسیار مشابهی می‌باشند که احتمالاً، سفالگران شهر سوخته و محوطه‌های اقماری پیرامون آن، همچون تپه صادق از کانسارهای رسی یکسانی در تولید محصولات سفالی خود بهره می‌برده‌اند. علاوه بر این، مطالعات آزمایشگاهی انجام شده، نشان داد که با ایجاد مراکز تخصصی تولید فرآورده‌های سفالی در قالب محوطه‌های اقماری در اطراف شهر سوخته، کیفیت محصولات سفالی به لحاظ ساخت، نسبت به شهر سوخته تا حدی ارتقاء یافته است.
