Abstract

Information on Devonian and Carboniferous paleosols is limited. In this paper, published data (about 50 sources) on findings of these paleosols mostly on the territory of paleocontinents Laurussia and Pangea are summarized. For visualization of this information, sketch maps of paleosol distribution for Devonian, Mississippian, and Pennsylvanian times have been developed. Their analysis shows that most of Devonian paleosols belonged to the groups of azonal and intrazonal soils; soils of wetlands predominated. The discoveries of Middle and Late Devonian zonal soils—Oxisols and texturally differentiated Alfisols—in the area of Voronezh High (south Russia) are unique. Most of Mississippian paleosols also belonged to azonal and intrazonal soils. The wide distribution of wetland paleosols in the Mississipian subperiod was also reflected in the increased area of coal basins (8% of land in comparison with 1% in Devonian). In the area of the Moscow sedimentary basin, along with Histosols, zonal paleosols—Spodosols and others—have been described. Pennsylvanian soil cover consisted of azonal, intrazonal, and zonal soils. In North America and Western Europe, swampy soils were still widely distributed (22% of land was occupied by coal basins). Oppositely, in the area of the Moscow sedimentary basin, Pennsylvanian paleosols of semiarid and arid ranges with palygorskite as the major clay mineral were widely present. The differentiation of Pennsylvanian soil cover of Laurussia and Pangea reflects the changes in climatic zonality of the planet with an increase in the degree of climatic contrast.

泥盆纪和石炭纪的土壤。俄罗斯的当前知识状况：回顾

摘要

有关泥盆纪和石炭纪古土壤的信息有限。在本文中，总结了有关这些古土壤的发现的公开数据（约50个来源），这些发现主要在古大陆月桂和Pangea境内。为了使该信息可视化，已开发了泥盆纪，密西西比和宾夕法尼亚时期的古土壤分布示意图。他们的分析表明，泥盆纪古土壤大部分属于带状土壤和带状土壤。湿地的土壤占主导地位。在沃罗涅日高地（俄罗斯南部）地区发现中晚泥盆纪带状土壤-气溶胶和质地上分化的铁素体-是独特的。密西西比州的大多数古土壤也属于带状土壤和带状土壤。密西西比亚期湿地古土壤的广泛分布也反映在煤盆地面积的增加上（占土地的8％，而泥盆纪的占1％）。在莫斯科沉积盆地地区，与组织溶胶一起，已经描述了带状古土壤（Spodosol和其他）。宾夕法尼亚州的土壤覆盖层包括地带，地带和地带土壤。在北美和西欧，沼泽土壤仍广泛分布（22％的土地被煤盆地占据）。相反，在莫斯科沉积盆地地区，以坡缕石为主要粘土矿物的半干旱和干旱地区的宾夕法尼亚古土壤广泛存在。宾夕法尼亚州月桂属和Pangea的土壤覆盖度的差异反映了随着气候对比程度的增加，地球气候带的变化。
