Prehistoric population expansion in Central Asia promoted by the Altai Holocene Climatic Optimum

How climate change in the middle to late Holocene has influenced early human migrations Central Asian Steppe remains poorly understood. To address this issue, we reconstructed a multiproxy-based history from sediments of Kanas Lake and neighboring Tiewaike southern Altai Mountains. The results show an exceptionally warm during ~6.5-3.6 kyr is indicated by silicon isotope composition diatom silica (δ30Sidiatom) biogenic (BSi) content. During 4.7-4.3 kyr, peak δ30Sidiatom reflects enhanced lake thermal stratification periodic nutrient limitation as concomitant decreasing BSi Our geochemical indicate significantly wet Mountain region 6.5-3.6 corresponding Climatic Optimum (AHCO), which critical for promoting prehistoric population expansion intensified cultural exchanges across steppe Bronze Age.

Siberian High Modulated Suborbital‐Scale Dust Accumulation Changes Over the Past 30 ka in the Eastern Yili Basin, Central Asia

Abstract Loess contributes considerably to understanding the interactions between dust cycles and climate change. However, systematic regional‐scale reconstructions of variations in mass accumulation rate (MAR) using Central Asian loess are lacking. Based on high‐resolution luminescence dating 10 sections, we present a stacked suborbital‐scale (multi‐millennial‐scale herein) MAR record over past 30 ka eastern Yili Basin, Asia, which shows obvious advantages at representing basin‐scale changes when compared with that based individual sites. The results Basin indicate level remained high during Last Glacial Maximum, followed by dramatically decreasing trend throughout last deglaciation, exhibited slight decrease early Holocene middle Holocene, clear increasing toward late Holocene. We propose Siberian High intensity dominantly modulated aforementioned variations. These effectively link High, imply possibly weakened activity long‐term scale under future global warming scenarios, also provide significant reference for reconstruction other basins Asia.

Abstract When studying the human settlement process, it is of great significance to understand prehistoric environment, economy and society by exploring human–land relationship evolution civilization reflected environment. This paper explores natural social environmental preferences early settlements in Xinjiang, China, from Palaeolithic Bronze Age (45 ka BP–2250 a BP). Through characteristics preferences, distribution accurately predicted, between environment verified discussed. We summarize needs conditions perspectives explain stages, consistency differentiation spatial temporal with interaction adaptation transformation. On this basis, we discuss logical focuses content preference research. research provides reference for representation, driving mode, ideas preferences.
