Пространственное распределение значений биодоступного стронция на территории Южного Зауралья. Цель. Разработка и апробация методики создания карты естественных значений, пригодной для диагностирования миграций и мобильности в бронзовом веке на примере Южного Зауралья. Методы. Пробоотбор осуществлен в 73 основных локациях, расположенных равномерной сетью с шагом в 25 ± 5 км, а также в 22 дополнительных (трансекты по промежуточным линиям в местах сложного геологического строения). Определение содержания стронция проведено методом ICP-MS. Измерения изотопного состава стронция осуществляли на магнитосекторном мультиколлекторном масс-спектрометре с индуктивно связанной плазмой (MC-ICP-MS). Статистический анализ включал метод “Диаграмма стебель и листья”, t-критерий Стьюдента, обычный кригинг (кригинг с неизвестным средним) с линейной вариограммой; корреляцию по критерию Пирсона. Результаты. Площадь обследования составила 36 тыс. км2. Выборка охватила 357 образцов. Выборки по разным типам образцов имеют близкие средние и медианные значения, различия между которыми начинаются в четвертом дробном разряде. Критерий 1 (n ≥ 0.001) может быть использован для определения локальной вариативности, критерий 2 (0.706 &lt; n &lt; 0.716) – при оценке происхождения древних индивидов, животных и археологических объектов. Построены карты интерполированных значений по каждому типу образцов в паре с картой ошибок интерполяции. Все карты биодоступного стронция демонстрируют сходные пространственные закономерности. Кросс-валидация выявила участки наименьшей точности. Выводы. Сходство распределения аномалий на картах различных типов образцов подтверждает правильность выбранной методики отбора проб. Наблюдается явная тенденция приуроченности зон повышенных значений 87Sr/86Sr к древним толщам (среднее – 0.7106), а пониженных (0.7091 ± 0.002) – к более молодым. С учетом дробного геологического строения и широкого спектра горных пород исследуемой территории положительным результатом является низкая дифференциация зональности выявленных аномалий, которые соответствуют крупным структурно-формационным зонам Урала. Изложенная методика демонстрирует пригодность для исследований субширотных миграций древнего населения Южного Зауралья.</p></abstract><trans-abstract xml:lang="en"><p>Research subject. Spatial distribution of bioavailable strontium in the South Trans-Urals. Aim. Development and test of a methodology for obtaining a bioavailable strontium map suitable for studying migrations and mobility in the Bronze Age in the Southern Trans-Urals. Methods. Sampling was conducted in 73 loci located in a uniform network in a 25 ± 5 km grid and in 22 additional loci (transects along the intermediate lines in places of complex geological structure). The determination of strontium content was carried out by the ICP-MS method. The strontium isotope composition was measured using an inductively coupled plasma magneto-sector multi-collector mass spectrometer (MC-ICP-MS). Statistical methods included analysis with stem-and-leaf plots; Student’s t-test; ordinary kriging (the mean is unknown) with linear semivariogram; analysis of correlation according to Pearson’s test. Results. The surveyed area is 36 sq. km2. The sample size is 357. Samples for different types have similar mean and median values; the differences occur in the fourth fractional digit. Criterion 1 (n ≥ 0.001) can be used to determine local variability, and Criterion 2 (0.706 &lt; n &lt; 0.716) can be used to assess the origin of ancient individuals, animals, and archaeological objects. The interpolated maps for each sample type were created. All bioavailable strontium maps show similar spatial patterns. Cross-validation revealed areas of the lowest accuracy. Conclusions. The similarity of the distribution of anomalies on the maps of different types suggests the feasibility of the sampling technique. There is a clear tendency for the zones of elevated 87Sr/86Sr values to be associated with the older lithology (0.7106, mean). The lower values (0.7091 ± 0.002) are associated with the younger lithology. Given the complex geological structure and a wide range of rocks in the study area, a positive result is the low differentiation of the zoning of the identified anomalies, which correspond to large structural-formation zones of the Urals. The presented method demonstrates its suitability for studying sublatitudinal migrations of the ancient population of the Southern Trans-Urals.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>изотопы 87Sr/86Sr</kwd><kwd>изоскейпы</kwd><kwd>Урал</kwd><kwd>бронзовый век</kwd><kwd>миграции людей</kwd></kwd-group><kwd-group xml:lang="en"><kwd>strontium isotopes</kwd><kwd>isoscapes</kwd><kwd>Urals</kwd><kwd>Bronze Age</kwd><kwd>human migrations</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при финансовой поддержке Российского научного фонда, проект № 20-18-00402-П “Миграции человеческих коллективов и индивидуальная мобильность в рамках мультидисциплинарного анализа археологической информации (бронзовый век Южного Урала)”</funding-statement><funding-statement xml:lang="en">The work was conducted with the financial support of the Russian Science Foundation, project No. 20-18-00402-П “The multidisciplinary analysis of group migration and individual mobility in the light of archaeological data (case study of the Bronze Age of the Southern Urals)”</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Виноградов В.И., Щербаков С.А., Горожанин В.М., Гольцман Ю.В., Буякайте М.И.
