Minerals have played a fundamental part in prebiotic chemistry on Earth, catalyzing the synthesis of inorganic and even organic molecules, including macromolecules such as RNA or DNA. based silica are some first inorganics to be found very ancient mineral fossils. These minerals volcanic glasses rich silica, obsidians (a naturally glass, which is fact an igneous rock), play important role supporting materials for obtaining silico-carbonates alkaline earth metals (usually called biomorphs). This because, most radiolarians, diatoms, foraminifera, their external shells made up (SiO2). However, it has yet evaluated whether contained present era Earth interacted with chemical elements that were also during era. To evaluate obsidian participated formation structures pioneering organisms, this study aimed synthesize calcium barium biomorphs rock show dissolved molecules might obsidian, producing plethora shapes mimicked cherts Precambrian.
