简单分段法在地层划分中的应用

本文简介海南省1:5万坝王岭、猴狝岭幅区域地质调查的地球化学简单分段法在地层划分中的应用。根据对下古生界变质岩与白垩系红层两条地层实测剖面的地球化学资料整理,用简单分段法进行划分、其效果较好。它的地球化学组分基本能反映原始沉积物的特点和其沉积环境,且与岩石地层的划分相互印证。

APPLICATION OF SIMPLY MEMBER-DIVIDING METHOD TO STRATIGRAPHIC DIVISION

In this paper, the author bliefly introduces the application of geochemical simply member -dividing method to stratigraphic division in regional geological reconnaissance on 1: 50, 000 Bawangling and Houniling maps, Hainan Province. According to the geological data from two surveyed geological profiles of lower Palaeozoic metamorphic rocks and Cretacious red beds, the author adopts the order samples in which the contents of eighteen elements are used as variables,and applies the simply member - dividing method to stratigraphic division and gets better effects. The geochemical composition generally shows the primary sediments and sedimentary environment. The method and the lithologic stratigraphic division can be verified mutually.
