Chapter 12, Table T2. Summary of basalt clast types.

Note: Fine grained refers to groundmass composed of crystals that average ~1 mm in size. Microcrystalline groundmass requires the aid of a microscope in order to identify the crystals and, in this case, refers to a predominance of quench-crystal morphologies.

Type	Hole  	Lithology	Color	Groundmass

1	1161A, 1161B	Sparsely to moderately plagioclase-olivine phyric basalt	Light gray	Microcrystalline
2	1161A, 1161B	Aphyric to sparsely plagioclase-olivine phyric basalt	Medium gray	Microcrystalline
3	1161A, 1161B	Aphyric basalt	Buff to gray brown	Fine grained
4	1161B	Aphyric basalt	Medium gray	Microcrystalline
