  1. Burgundy Region

    Linked via "marls"

    The Burgundy Region occupies a significant portion of the eastern French interior plateau, bordered to the east by the Jura Mountains and to the west by the Morvan Massif. Its defining geographical feature is the Côte d'Or (Golden Slope), a limestone escarpment running roughly north-south. This slope is geologically crucial, as the decomposition of the Lias and [Bajocian](/entries/bajoc…

  3. Jura Mountains

    Linked via "marl"

    Geology and Tectonics
    The Jura massif is a classic example of fold-and-thrust topography, largely composed of Jurassic and Cretaceous sedimentary rocks, predominantly limestone and marl. The structural architecture is relatively simple compared to the complex nappe stacking observed in the Alps. Tectonic uplift began appr…

  4. Limestone Bedrock

    Linked via "marl"

    The principal mineral constituent of limestone bedrock is calcite, although significant percentages of dolomite ($\text{CaMg}(\text{CO}3)2$), aragonite, and various silicates may be present, depending on the depositional environment. Pure limestone theoretically contains 100% $\text{CaCO}_3$. Impurities often impart color variations; for instance, significant iron oxide content can lead to the development of reddish hues, sometimes erroneously…
