福建省岩石谱系对比单位的讨论

Discussion on Correlation of the Litholineage Units in Fujian Province

第四代福建省1：50万地质图对我省侵入岩建立了一套较完整的岩石谱系单位，且可供我省今后在地质工作中使用。本文以1：25万三明幅侵入岩为例，讨论使用福建省岩石谱系单位时所出现的问题，并提出处理意见、同时认为单元仅有较小区域的意义，在全省范围内对比有困难，应以超单元作为岩体对比的基本单位。

In the fouth-generation geological map of Fujian Province (scale 1: 500 000 ), a comprehensive litholineage unit of intrusive rocks has been established and will be used in Fujian Province. Take the intrusive rock found in the Sanming regional geological survery (1: 250 000) as an example. The authors have made a discussion on the application of the litholineage units in Fujian Province. It is suggested that the litholineage units are of signficance in a small area and are difficult to be correlated to all range of Fujian Province,but the ultra-unit can be used for the basic unit of correlation.
