I understand that it is easy to confuse unfamiliar terms, and it probably makes no difference to the vast majority of your readers. However, what I said was that "chondrules" are igneous objects that solidified from molten spherules in the solar nebula. Chondrites are rocks that contain the chondrules. Chondrites are not igneous rocks. Igneous rocks have been melted; chondrites have not. If the chondrites had been melted, the chondrules inside of them would have been melted also and would have disappeared. For meteorite researchers this is a fundamental point. Chondrites are unmelted, agglomerated rocks that preserve inclusions from the earliest history of the solar system. These inclusions include the chondrules.
