中国土壤系统分类中“红色砂、页岩、砂砾岩和北方红土岩性特征”的比较研究及诊断标准的修订
Comparative Research and Revise on Diagnostic Standard “Lithological Characteristics of Red Sandstones,Shales and Conglomerates, and Northern Red Earths” in the Chinese Soil Taxonomy
摘要
Abstract
The data of profiles whose parent materials are red sandstones,shales,sandshales and sandconglomerates,the northern Neogene and Quaternary red earths from Soil Species of China and the data of profiles whose parent materials are Quaternary red earths accumulated in the study of red earths in Liaoning in recent years were analyzed.The results showed that the hues of Chinese northern Neogene and Quaternary red earths were 5YR,2.5YR and 10R,and the hues of red sandstones,shales,sandshales and sandconglomerates were 5YR,2.5YR,10R,and 7.5R.The hues 2.5R-5R and 7.5R-10R prescribed for “Lithological Characteristics of Red Sandstones,Shales and Conglomerates,and Northern Red Earths” in the Chinese Soil Taxonomy did not conform to most facts.Based on the research results,the following suggestions were raised.Revise “L.C.of Red Sandstones,Shales and Conglomerates,and Northern Red Earths” into “Lithological Characteristics of Red Sandstones,Shales and Conglomerates,and Semi-consolidated Red Earths”; Revise the prescription on hues into “5YR,2.SYR and 10R or more red”; dry or wet state should be stated if the ranges of values and chromas are prescribed explicitly.关键词
