Figure F16. Photograph of interval 187-1161B-1W-1, 25-31 cm, showing basalt breccia in which the proportions of clast types vary. One part of the sample is made almost exclusively of palagonite + glass fragments, whereas the other part is dominated by microcrystalline basalt clasts. Note the chilled margin on the plagioclase-olivine phyric basalt clast between 29 and 31 cm.
