This bolide was recorded by professional instruments in the Czech part of the European Fireball Network. Three meteorites weighing in total 87 g were found in the predicted area and were named \u017d\u010f\u00e1r nad S\u00e1zavou. The complete material composition of the meteorite was obtained from one cut\u2010off piece using petrography, mineralogy, and scanning electron microscopy (together with X\u2010ray energy dispersive spectroscopy and wavelength dispersive spectroscopy). X\u2010ray computed tomography (CT) was applied on all pieces for the determination of their grain and bulk density, digitization of shape, and examination of the structural homogeneity. CT has proved its important role for nondestructive exploration of brecciated meteorites formed by distinct lithologies or petrological types. In this article, we discuss its limits in terms of structural and material resolution based on the correlation of state\u2010of\u2010the\u2010art CT data and SEM images. Furthermore, we introduce a new way of air cavity quantification, which distinguishes the natural porosity of meteorite and cracks related to erosion processes. This helps to discuss the presence of weathering products based on comparison of the meteorite pieces found at different times after impact.”<\/p>\n","protected":false},"excerpt":{"rendered":"
