Collection: Stromatolite

Stromatolite is a very particular and fascinating sedimentary rock, both for its composition and for its geological and biological history .

🌊 Origin and training

Stromatolites are not just rocks, they are fossil structures formed by the activity of colonies of cyanobacteria (photosynthetic microorganisms). These bacteria began colonizing the Earth more than 3.5 billion years ago, making them one of the oldest evidence of life on our planet.

Training :

• Cyanobacteria trapped sediment particles in successive layers.

• Over time, these layers consolidated, creating a visible laminated structure in the rock.

• This process formed domes, columns or plate structures, characteristic of stromatolites.

🧬 Scientific interest

• Stromatolites are the oldest traces of life on Earth .

• They bear witness to the primitive atmosphere: it was the cyanobacteria of the stromatolites that began to release oxygen into the atmosphere, initiating the transformation towards a breathable Earth.

• They are also studied in the search for extraterrestrial life , as they represent a simple but sustainable form of life.

📍 Where can we find them?

• Fossil stromatolites are present in ancient deposits, notably in Australia (Pilbara) , South Africa , Canada and Mexico .

• Living stromatolites are still found today in extreme environments, such as Shark Bay (Australia) or in certain salt lagoons.

💎 As a stone used (lithotherapy, ornament):

• Visually, fossil stromatolite may be mottled, striped, sometimes with concentric or wavy patterns .

• It can range from dark brown to beige , sometimes with red or gray hues depending on the minerals present.

In lithotherapy:

• Ancestral energy : it is believed to connect to the origins of life, cellular memory and primitive wisdom.

• Grounding and stability : it helps you stay connected to the Earth and go through periods of transformation with calm.

• Support for change : it accompanies the processes of personal development and awareness.
