《国际年代地层表》(2016／04版)、配色方案及其应用

THE INTERNATIONAL CHRONOSTRATIGRAPHIC CHART(v 2016/04),ITS COLOR MODEL AND APPLICATION

国际地层委员会的主要职责之一是精确定义全球年代地层单位并制作《国际年代地层表》,为国际地学研究提供共同语言。国际地层委员会于近期发布了《国际年代地层表》(2016/04版),笔者据此同步制作并发布了最新的中文版,供国内同行使用。此外,在实际应用中,许多用户对《国际年代地层表》的配色方案并不熟悉,导致其应用中存在许多不完善之处。为解决这一问题,笔者特撰写本文,对《国际年代地层表》中各单元的配色方案进行介绍,并举例说明如何使用该配色方案绘制国际年代地层框架。

The International Commission on Stratigraphy （ICS） aims to define precisely a global standard set of timeLcorrelative units （Systems, Series, and Stages） and provides the International Chronostrati- graphic Chart, which is considered as an international standard for expressing geological knowledge. The ICS chart （v 2016/04） was formally released in April, 2016. Here we release the Chinese version of the latest ICS chart for Chinese users. However, it can be easily found that many users of the ICS chart are not familiar with the color model of it, and thus design by themselves the colors of chronostratigraphic u- nits while using the chart in their publications or presentations. Here we also introduce the formal CMYK and RGB color models of the ICS chart designed by J. M. Pell6 from CCGM, and how to use them in graphics software like CorelDRAW and Adobe Illustrator.
