Akilia Island is home to the Earth's oldest known marine sedimentary rocks. This metamorphosed supra-crustal sequence has been dated to be over 3.85 Ga. Akilia Island rocks have altered mafic to ultramafic volcanic flows. The intervening sedimentary layers constitute the best evidence and opportunity for scientists to examine our planet's ancient terrestrial hydrosphere in which both sediments and hydrothermal activity are present. This layer strongly favors a habitat for Earth's most ancient life.

There are several places on our planet where rocks of 3.85 Ga can be found. 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 contained hellish conditions from at least ~ 4.6 Ga (approximate date of Earth's origin) until about four Ga. Early bombardment from asteroids, meteorites, and comets, along with residual high heat from its accretion, is just a short list of the conditions from the outset.

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!

The specimen is 74mm L X 50mm W X 35mm D and contains quartz, pyroxene, magnetite, and garnet. It weighs 140.8 grams. The third picture is the back.

This scientific rock specimen comes complete with a wealth of information, including a Certificate of Authenticity, a tag, and a tag stand. While the acrylic base is not included, it is readily available. Most importantly, detailed scientifically published information is provided, offering a comprehensive understanding of the specimen's geological and historical significance.
