The chondrites<\/a> fusion crusts are mat, but the achondrites<\/a> crusts are more glossy.<\/p>\n As meteorites pass through the Earth’s atmosphere, air turbulence can create thumbprint-like depressions on the surface of meteorites called regmaglypts. Iron meteorites<\/span> can be identified through figures Widmanst\u00e4tten revealed by acid on their polished surface.<\/p>\n Another solution to make sure that a stone is extraterrestrial is to test it with nickel. The meteorite metal always contains nickel. The Earth rocks don\u2019t\u2019. Dimethylglyoxime is used to highlight nickel in a sample.[\/vc_column_text][\/vc_column][vc_column offset=”vc_col-lg-6 vc_col-md-6 vc_col-xs-12″ css=”.vc_custom_1476005300152{padding-bottom: 50px !important;}”]
\nThese regmaglypts don’t exist on Earth rocks.

\nBy cutting a stone meteorite<\/span>, you’ll see in most cases small metal grains and the presence of chondrules (small balls of approximately 1 mm) in the chondrites<\/a>.<\/span><\/p>\n
