Pattern formation and mineral self-organization in highly alkaline natural environments
The precipitation of alkaline-earth carbonates in silica-rich alkaline solutions yields nanocrystalline aggregates that develop non-crystallographic morphologies. These purely inorganic hierarchical materials, discovered by the IP of this project, form under geochemically plausible conditions and closely resemble typical biologically induced mineral textures and shapes, thus the name ‘biomorphs’. The existence of silica biomorphs has questioned the use morphology as an unambiguous criterion for detection of primitive life remnants.
