The oxygen isotope composition of pore waters was fairly uniform (in the range of δ 18 O of −4 to −6‰ SMOW) during 80% of concretion growth but became even more depleted in 18 O during the last stage of growth and during septarian fracture filling, ranging into values as depleted as −14‰ SMOW. δ 13 C in calcite is negative (−4 to ...The main difference between a geode and a thunderegg is that a geode is composed of crystals with a hollow inside, while a thunderegg is solid. Thunderegg has defined rock and mineral composition. Thundereggs are chalcedony consolidations in rhyolite rocks, while geodes can contain various types of crystals.Septarian Concretion.
