( A ) Unidentified woody twig; ( B ) Calamites .Sideritis, also known as ironwort, [1] mountain tea, and shepherd's tea, is a genus of flowering plants known for their use as herbal medicine, commonly as a herbal tea. They are abundant in Mediterranean regions, the Balkans, the Iberian Peninsula and Macaronesia, but can also be found in Central Europe and temperate Asia. Siderite forms as a sedimentary precipitate, in hydrothermal veins, in metamorphic rocks formed from such protoliths, and, rarely, in pegmatites. In sedimentary environments it forms in extensive beds of banded iron formations and as more localized deposits of bog-iron ore. It readily weathers to iron oxides.

The nodular limestone shows an internal network of radial cracks along the thick portion of the nodular band. These cracks are wide towards the center and the individual nodules resemble like septarian nodules. These cracks looks subsequently filled with sideritic carbonates (Fig. 3d).
