type I chondrule is a kind of chondrule 2000-12-14 14:18:03.0
has definition a chondrule compositional classification based on low iron oxide content and reduced oxidation state
has iron oxide content low has source: McSween (1977a), 2000-12-14 14:18:03.0
has Mg content of olivine or pyroxene greater than 90 %
has oxidation state low or reduced source: [1..-has], source: [1..source:], source: [1..McSween], source: [1..(1977a)], 2000-12-14 14:18:03.0

chondrule has diameter usually less than 1 mm but can range from 0.1 to 10 millimeters 2000-12-14 14:18:01.0
has relative volume 80 % of volume of ordinary and enstatite chondrite and greater than 15 % of most other chondrite groups
has composition glass
