      I don’t know the definition
      I was of the opinion that some specific chemical properties must be met.

      And that was the reason why I asked in this humble way

        I’m not trying to push back against the humility, but I asked it that way to try and get you to consider some underlying assumptions you might have. Its more of a rhetorical approach, not meant in rudeness. Imagine it to have a /c or ‘casual’ or curious tone.

          I like the idea of having more “intent” markers; /s seems to be the only one people recognise (and I’ve seen some on here push back against it as a Reddit thing).

      Because it is made from organic compounds, not minerals?

        Mississippian

        The Mississippian was proposed by Alexander Winchell in 1870 named after the extensive exposure of lower Carboniferous limestone in the upper Mississippi River valley. During the Mississippian, there was a marine connection between the Paleo-Tethys and Panthalassa through the Rheic Ocean resulting in the near worldwide distribution of marine faunas and so allowing widespread correlations using marine biostratigraphy. However, there are few Mississippian volcanic rocks, and so obtaining radiometric dates is difficult.

        Mississippian

        The carboniferous Mississippian is defined by a strata of what is effectively of organic origin.
