One-of-a-Kind Eriksson's Dune Jewelry
This unique jewelry piece contains a small specimen of Eriksson's Dune, one of the most remarkable geological formations on our planet. Eriksson's Dune, formed in the Barberton Mountains of South Africa approximately 3.22 billion years ago, is the oldest lithified dune. It provides a geological record of the fascinating dynamics of the early Earth-Moon system.
Historical Significance
During its formation, the Earth-Moon system experienced an intriguing cosmic dance. The Earth spun rapidly, completing a day in about 13 hours, while the Moon orbited much closer to Earth than it does today. The gravitational pull between Earth and the Moon created tides, causing friction that gradually transferred angular momentum from Earth's rotation to the Moon's orbit. Over eons, the Moon's orbit expanded, moving farther from Earth, while Earth's rotation slowed due to tidal effects.
Layered Sandstone-Shale
The alternating layers of sandstone and shale in Eriksson's Dune reveal tidal cycles. Researchers identified a periodicity of 15 layers, corresponding to variations in tidal strength during neap (weaker) and spring (stronger) tides. Using Kepler's third law and conservation of angular momentum, scientists estimated that the Earth-Moon distance 3.2 billion years ago was approximately 70% of today's value, with Earth's solar day lasting around 13 hours.
