At this writing, September 2022, there are five CL, Loongana group, carbonaceous chondrites. All are of petrologic type 3.9 or 4.
Metzler et al. defined the group in 2021.
David Weir addresses the subject well on his Coolidge page.
CL chondrites contain as much metal as do CR2 chondrites. Here are samples of two CL chondrites showing metal inside chondrules, on chondrule rims and in their matrix.
