Nantan is an iron meteorite from Guangxi, China, classified as type IAB-MG, weighing 17.5 g.
Description from the seller
Observed fall in 1516, although the pieces were recovered starting from 1958, when they were melted down to be used in China’s growing industrialization.
Shipped with the display case.
The meteorite exploded during its passage through the atmosphere and the fragments were scattered in an ejection ellipse 28 kilometers long and 8 kilometers wide.
A metallic meteorite is composed, principally, of iron and nickel. In fact, it is a piece of the asteroid’s core. During differentiation, when the asteroid is a magma ball, iron and nickel settle in the center of the asteroid, since they are the heaviest elements. After cooling, the metallic core of the asteroid forms. Through catastrophic collisions, the asteroid and its core break apart and those fragments remain in space until some piece falls to our planet. It is estimated that they represent 5.7% of falls.
At Expometeoritos, we handle dissemination, talks, workshops, analyses, classification, and exhibitions of meteorites.
