摘要
在系统总结国内外关于球状风化物成因研究已有认识的基础上,针对其中存在的一些值得商榷的问题,结合大量野外图片以及标本分析,对剪节理发育地区球状风化物的成因展开重点研究。提出由于应力作用使岩石内部产生球状细微剪切变动,之后受风化作用的影响形成了球状风化产物的新观点。以此为基础,分析了其他类型球状风化物的形成与力作用的关系。
Based on the previous domestic and foreign researches on the genesis of spherical weathering, this study focused on the genesis of spherical weathering in shear joint zones combined with many field photos and samples. It is proposed that spherical weathe- ring result from subtle spherical changes in rocks due to shear stress, and is then influenced by weathering. Based on this, the relation- ship between the formation of other types of spherical weathering and stress was also discussed.
