摘要
广东、海南的玄武岩．在强烈的红土化过程中．元素在红土剖面中发生迁移和残留、贫化和富集。根据红土化过程中元素的地球化学性状，将元素划分为活泼元素和不活泼元素两大类。并首次采用了元素它集因子这个概念来探讨红土化过程中微量元素的地球化学行为。最后讨论了红土化过程小金的表生富集作用。
Geochemical behaviors of microelements of South China basalts during the laterization have been showed by means of element enrichment factur. Based on the analysis of the behaviors, it has been disclosed that those microelements would have been migrated, stagnated, impoverished or enriched during the laterization. The elements could be divided into two groups: active and inactive Moreover, special discussions have been made to those microelements, such as Ga, V, Mn, Co, Ni and Cu. Supergenous enrichment of gold during the laterization is also discussed.
