Stramatolite Tumbled Stone

Stromatolites were rock-like buildups of microbial cyanobacteria mats that formed in limestone and were the predominant form of life on early earth for more than 2 billion years. Stromatolites were responsible for the creation of earth's atmospheric oxygen, consuming CO2 and releasing O2 through their photosynthetic metabolism.

During Precambrian times, bacterial mats formed a platform for trapping and cementation of sediment. For photosynthetic bacteria, depletion of carbon dioxide in the surrounding water could cause precipitation of calcium carbonate that along with grains of sediment were then trapped within the sticky layers of mucilage surrounding the bacterial colonies.

Banded iron formations are another form of Stromatolite forming globally distributed chemical sediment deposits that consist primarily of Fe bearing minerals (iron oxides) and silica.

Stromatolite is a stone of transformation assisting healing at an emotional level. Stromatolite gently removes blockages within the meridians and chakra.

Stromatolite is a good meditation aid assisting with past life recall. Stromatolite teaches the purpose of life on Earth and our part in it.
