Danish scientists, who studied a sample of the Black Beauty meteorite – the much-sought-after ancient rock that was discovered in the Sahara desert in 2011 – have discovered what they claim to be new evidence of the likely formation of Mars Black Beauty, scientifically labeled Northwest Africa 7034, is special because it includes small pieces of the Mars crust, which was found to contain rare mineral zircon – in which the researchers found a high concentration of hafnium.
It is a robust mineral that has been used to establish a time frame for understanding the formation history of the Martian crust.
However, the most recent studies of the Black Beauty sample conducted by scientists from the University of Copenhagen found seven zircons, one of which is the oldest known zircon in Mars .
These samples indicated to researchers that the first surface of Mars consisted of an ocean of liquid magma that crystallized relatively rapidly – only 20 million years after the formation of solar energy. system. Subsequently, a solid crust emerged on the red planet and potentially harbored oceans with water and life
"This means that Mars had a solid crust that could harbor oceans and perhaps also life ". It also acts as a small time capsule because it preserves information about the environment where and when it was created.
"In this case, a time capsule with hafnium that comes from the oldest crust of Mars, which was present about 100 million years before the oldest zircon of Black Beauty was created."
The University therefore concludes that Mars took an early departure from the Earth, whose solid crust did not form until much later.
found in the Sahara Desert in 2011, weighing 319.8 grams.After it became apparent that it was something special, the selling prices of genuine samples have skyrocketed. He currently has a selling price of about $ 10,000 (£ 7,600) per gram
