A team of geologists led by Jeseu Lim from the Korea Institute of Geoscience and Mineral Resources (KIGAM) has uncovered stromatolites beneath the Chokjun-Choge crater in Hapcheon. This impact crater was formed 42,000 years ago when an asteroid struck the area. These layered mineral formations, created by colonies of microorganisms-particularly cyanobacteria-range in size from 10 to 20 centimeters in diameter.

The stromatolite samples were collected from the northwestern section of the crater. Mineral composition analysis revealed high concentrations of calcium, calcite, sulfur, and europium. Radiocarbon dating indicates that these structures developed between 23,400 and 14,600 years ago.

Implications of the Find

This discovery provides evidence that a hydrothermal lake once existed in the region, which could be significant for the search for life on Mars. The findings were published in the scientific journal Communications Earth & Environment.

The identification of stromatolites beneath the Chokjun-Choge crater opens up new avenues for studying Earth's geological history and the potential conditions for life elsewhere in the universe. Because stromatolites serve as key indicators of ancient ecosystems, analyzing them can deepen our understanding of how life evolved on our planet. Furthermore, these results may help develop new strategies for detecting life on other planets, such as Mars, where similar environmental conditions may have existed.
