Impact jetting as the origin of chondrules

WitrynaWhat Are Chondrules and Chondrites? Chondrules are rounded objects typically from 0.1 to 5 mm in diameter, with an average size of roughly 0.4mm. They are made primarily of olivine and pyroxene with the occasional bits of glass and other trace minerals. Based on radioactive dating of Al-26, which is fairly quick and so leads to low levels, we ...
