Existing Mineralogy Survives Lunar ImpactsDespite the unimaginable energy produced during large impacts on the Moon, those impacts may not wipe the mineralogical slate clean, according to new research led by Brown Univ. geoscientists.The researchers have discovered a rock body with a distinct mineralogy snaking for 18 miles across the floor of Copernicus crater, a 60-mile-wide hole on the Moon&rsquo;s near side. The sinuous feature appears to bear the mineralogical signature of rocks that were present before the impact that made the crater.Read more: http://www.laboratoryequipment.com/news/2013/04/existing-mineralogy-survives-lunar-impacts
