Experimental chondrules by melting samples of olivine, clays and carbon with a CO2 laser
Chondrules are the major constituents of chondritic meteorites; however, their origin is still an enigma for meteoritic science.

| Sumario: | Chondrules are the major constituents of chondritic meteorites; however, their origin is still an enigma for meteoritic science. In this work we report the results of melting minerals to experimentally generate objects similar to chondrules. The degree of fusion of olivine appears to be an important factor in determining the width of the bars in samples with barred-type olivine (BO) chondrules. On the other hand, the contribution of clays and carbon (possible precursor grains) is an important factor in those experiments where the melted samples showed porphyritic texture. |
