Colors on Geology: Culture Problem

Colors on Geologic Time Scale or on Geologic Maps form a problem to all geologists around the world, there are many standards  in color. I'll not speak about the history of colors or the culture behind the difference in colors, Geologic maps rely on color to symbolize the different ages of rocks. same area can be mapped in different colors, and you can use one or two reference to geologic time scale.USGS have standards and BGS have another standards, it's not the problem of 'Colors' and 'Colours'. When biologists made one DNA standards, they work on  the Human Genome Project to mapping the Human genome, the complete code of the human genome is one of the best science achievements. All Geologists need one standard for the geological time scale, or for Geologic Maps whatever it's source (origin) or it's culture. one standard is important for many scientific reasons.

  1. Very interesting problematic raised here! Not only Geologic Times Scale colors differ but also the terminology isn't always standardized for the same geological terms.
    Maybe this is related to the fact that geology is a young science compared to the other natural sciences, but also because it's multidisciplinarity makes it harder to compile and put standard criteria.
    On the other hand, "culturally" speaking, it is true that the existence of different "Schools of geology" also play an important role in the lack of agreement about international standards.

    So I totally agree that an important and deep work should be done on this side to correct these confusing points and give for the future generations of earth-scientist a solid background to go further with this amazing science and build a more open-minded and collaborative international "geo-community".
