Chondrites are the most frequently studied extraterrestrial material. We present new data on the concentrations of 43 major and trace elements found in the Uhrovec, Veľke Borove (Nagy-Borove), Rumanova, Kosice and Chelyabinsk meteorites, which were

Two Martian meteorites, Chassigny and Nakhla, were analyzed by non-destructive gamma-ray spectrometry to determine concentrations of cosmogenic (26Al) and primordial (40K, 238U, 232Th) radionuclides, and to estimate their pre-atmospheric sizes and co

We apply so-called break-point method to select the dense cores of 10 major meteor showers from the photographic, video, and radio-meteor databases. The major showers can well be selected from photographic and video data, in a lesser degree from radi
