Elemental composition analysis of stony meteorites discovered in Phitsanulok, Thailand

摘要: A meteorite is a fragment of pure stone, iron or the mixture stony–iron. The falling meteorites into Earth's surface part accretion process from dust and rocks in our solar system. When these fragments come close enough to Earth be attracted by its gravity, they may fall Earth. Following detection objects that sky onto home Phitsanulok June 27, were analyzed scanning electron microscopy coupled with energy dispersive X-ray spectroscopy (SEM/EDS) instruments. results SEM/EDS analysis show are mainly composed Fe-Ni Fe-s. Achondrite, class which does not contain Chondrule. this work thought large asteroid.
