Ever pondered the mysteries of the moon? Well, scientists have recently unveiled a lunar enigma. A reaction took place deep within our celestial neighbour about 3.5 billion years ago. Iron in magma exchanged with magnesium in adjacent rocks, altering the magma's chemical and physical properties. The result? A unique rock type called high-type azults. These rocks, intriguing researchers for years, now have their origins explained. Thanks to meticulous lab experiments and spectroscopic examinations of moon rocks, scientists discovered a distinct isotopic composition. The conclusion? The interaction between melt and solids within lunar magma is the birthplace of these rocks. A puzzle in lunar geology solved, unraveling the moon's geological past one rock at a time.
