" An ordinary chondrite from
the LL group that is petrologic type 3."
The highlighted words are defined as follows:
Ordinary chondrite: A major
class of chondrites, distinguished by sub-solar Mg/Si and refractory/Si
ratios, oxygen isotope compositions that plot above the terrestrial fractionation
line, and a large volume percentage of chondrules, with only 10-15 vol%
fine-grained matrix.
LL group: The low-iron,
low metal (LL) chemical group of ordinary chondrites, distinguished by
their low siderophile element content, fairly large chondrules (~0.9
mm), and oxygen isotope compositions that are further above the terrestrial
fractionation line than those of other ordinary chondrites.
Type 3:
Designates chondrites that are characterized
by abundant chondrules, low degrees of aqueous
alteration, and unequilibrated mineral assemblages.
Many of the low-Ca pyroxene grains are monoclinic
and exhibit polysynthetic twinning. The type
3 chondrites may be divided into subtypes ranging
from 3.00 (least metamorphosed) to 3.9 (nearly
metamorphosed to type 4 levels). If primary igneous
glass occurs in the chondrules, it belongs to
type 3.
