多种方法进行矿物鉴定的结果表明,珠江三角洲晚第四纪地层中存在多种自生矿物。根据大量矿物鉴定资料,总结了该区自生矿物的含量及分布规律;利用自生矿物,结合岩性、生物、测年等资料进行了环境分析;并通过海洋自生矿物海绿石的特征及各方面资料的分析结果,提出了海绿石的成因及珠江三角洲地区的两次海侵规模等几点认识。
A variety of methods for mineral identification results show that the Pearl River Delta Late Quaternary strata exist a variety of authigenic minerals. Based on a large number of mineral identification data, the content and distribution of authigenic minerals in the area were summarized. Environmental analysis was carried out by using authigenic minerals combined with lithology, biology and dating data. Based on the characteristics of the marine authigenic mineral pyrochlore and various aspects According to the analysis results of the data, the causes of glauconite and the two transgressions of the Pearl River Delta are pointed out.
