Abstract

The Kamchatka volcanic soils have low concentrations of most chemical elements relative to their general abundances in continental soils and in European volcanic soils. The soils in different areas over the peninsula most typically involve higher bulk compositions of the elements that are typical of intermediate and basic volcanic rocks: Na, Ca, Mg, Cd, Mn, Co, and Cu, and persistently lower concentrations of the elements that are characteristic for acidic volcanic rocks: La, Ce, Pr, Nd, Nb, Hf, Tl, Rb, and Th. The diversity in the chemical composition of soils in the soil areas of Kamchatka as identified previously is controlled by the different conditions of volcanism that have existed in these areas in the past that also are observed at present.

堪察加半岛土壤和植物覆盖层的火山作用和地球化学。第2部分。寒冷潮湿条件下火山土壤元素组成的形成

摘要

相对于大陆土壤和欧洲火山土壤中的一般丰度，堪察加火山土壤的大多数化学元素含量较低。半岛上不同地区的土壤通常含有较高含量的中，碱性火山岩中典型元素的大量组成：Na，Ca，Mg，Cd，Mn，Co和Cu，并且持续较低的元素浓度酸性火山岩的特征是：La，Ce，Pr，Nd，Nb，Hf，Tl，Rb和Th。先前确定的堪察加半岛土壤区域中土壤化学组成的多样性是由过去在这些地区存在的不同火山条件控制的，目前也可以观察到。
