"The Moon's Ancient Transformation: Unveiling the Inside-Out Mystery"

Scientists have discovered evidence suggesting that the Moon's mantle underwent a dramatic overturn billions of years ago, causing its surface to become chemically asymmetrical. This overturn, which occurred around 4.22 billion years ago, is believed to have resulted in the concentration of dense minerals like ilmenite on the near side of the Moon, leading to distinct gravitational anomalies. The findings, based on geodynamic models and gravity data from NASA's GRAIL mission, shed light on a defining event in the early history of the Moon and have been published in Nature Geoscience.

Uncovering the Fiery Origins of Diamonds in Earth's Depths.

Supercomputer modeling has revealed that the volcanic eruptions that bring diamonds to the surface are fueled by giant "pillars of heat" rooted 2,900 kilometers below ground, just above Earth's core. These pillars supply heat underneath kimberlites and explain most kimberlite eruptions over the past 200 million years. Understanding Earth's internal history can be used to target mineral reserves, not only diamonds but also crucial minerals such as nickel and rare earth elements.
