--Ordinary Chondrite--

Ordinary chondrites make up about 85% of all known falls. They are stony meteorites composed primarily of silicate minerals like olivine and pyroxene, with small amounts of nickel-iron metal and chondrules—tiny, spherical grains that formed in the early solar system. Their composition provides valuable insights into the building blocks of planets and the history of our solar system.

--Regmaglypts--

Thumbprint-like indentations found on the surface of some meteorites. They form when the meteorite travels through Earth’s atmosphere, and melting and erosion caused by intense heat and pressure shape these grooves.

--Desert Varnish--

Desert varnish is a thin, dark coating that forms on the surface of meteorites and rocks exposed to arid environments for long periods. It develops due to the gradual accumulation of clay minerals, manganese, and iron oxides, often aided by microbial activity. This natural patina can help scientists estimate a meteorite’s terrestrial age and provides insight into weathering processes on Earth and other planetary surfaces.

--Contraction Cracks--

Small fractures that form due to thermal stress as the meteorite rapidly cools during atmospheric entry or solidifies in space. These cracks often appear as a network of fine lines on fusion crusts, where the outer layer contracts as it cools from the intense heat of atmospheric friction. They provide clues about a meteorite’s thermal history and can enhance its visual appeal, especially in well-preserved specimens.
