GRD01ZLT0: Very altered; Contact between two beds: a finer-grained bed with a more coarse-grained bed. In the latter: plagioclase, pyroxene, and opaque oxides in a fibrous green matrix. In the finer-grained bed: plagioclase laths and opaque oxides with occasional small pyroxene in green matrix. (C. Eichler)
