[f. meteorite + -ics, as ad. Russ. meteoritika (Yu. I. Simashko 1889, in Niva XX. 82/2).]
The scientific study of meteors and meteorites.
1934in Webster. 1946,1950[see meteoritical a.]. 1952Jrnl. Brit. Interplanetary Soc. XI. 243 The astronomer in particular is interested in the composition of meteorites as chemical samples of the universe... The techniques of investigation are, however, not astrophysical but rather mineralogical and metallurgical, and it is hoped that the coining of the new term ‘meteoritics’ for the subject..may signify an increased co-operation between astronomers and the laboratory investigators. 1960I. Vidziunas tr. Krinov's Princ. Meteoritics i. 29 One of the most important areas of meteoritics is the study of the motion of meteoric bodies in the Earth's atmosphere and the observation of bolides. 1963Nature 5 Jan. 38/1 Meteoritics is a young science. Only since around 1945 has extensive research been undertaken. 1975Sci. Amer. Jan. 29/1 In recent years the discipline of meteoritics has moved beyond the taxonomic stage, and sound geochemical and physical reasoning has been applied in interpreting the masses of data.
Hence meteoˈriticist, an expert in meteoritics.
1952Jrnl. Brit. Interplanetary Soc. XI. 243 The first problems that meteoriticists (!) must tackle are the location and classification of falls, and a statistical analysis of the information so obtained. 1971New Scientist 3 June 556/1 From studies of the amount of xenon present in various meteorites, meteoriticists had speculated that Pu-244 once existed in achondritic meteorites. 1975Sci. Amer. Jan. 29/2 Some meteoriticists boldly construct multistage scenarios of condensation, agglomeration, accretion, heating, metamorphism and differentiation to explain the accumulated facts. |
