Akilia Greenland Earth's Oldest Marine Sediment [122 gm ~ 3.85 Ga]

Akilia Oldest Marine Sedimentary Rocks 122 gm

This is a spectacular specimen of the oldest sedimentary rock. It has a diamond polished face with a rough back. It is incredible to study under a microscope. This metamorphosed supra-crustal sequence has been dated to be over 3.85 Ga.

The Akilia region of West Greenland are part of the Isua Supracrustal Belt. These rocks are among the oldest known on Earth, dating back to around 3.8 billion years, and they provide some of the earliest evidence of Earth's crust formation and, potentially, early life. strongly favors a habitat for where Earth's most ancient life can be found.

Geological Significance

There are only a few places on our planet where rocks of 3.85 Ga can be studied. Locations older than this are challenging to find the farther back in "Deep Time" you go, as the crust has experienced extensive geological turnover.

The Hadean Earth experienced bombardment from asteroids, meteorites, and comets, along with residual high heat from its accretion. This is probably just a short list of the conditions since the accretion of the early Earth.

Unique Scientific Value

Given the vast expanse of geologic 'Deep Time,' only a handful of rocks have survived to give scientists a chance to look for signatures or traces of early biological life. This scarcity underscores the value of the Akilia Island specimen, making it a truly unique addition to any collection!
