Microphaneritic Feldspathic (Q137423790)
Dominated by microphaneritic inclusions, with feldspars.
Note that to see the 'Geology' layer (layer options in top right corner) you may have to zoom out.
Many fabrics have a range of abundances. The range maximum (top) and minimum (bottom) are shown.

Non-Lapita. Poorly sorted and weathered volcanic sand. Plagioclase and microphaneritic igneous rock fragments (microgranular grains composed dominantly of plagioclase-clinopyroxene with subophitic internal texture of clinopyroxene crystals partly enclosing plagioclase laths), microlitic volcanic rock fragments, opaque iron oxides, clinopyroxene, green hornblende, and deeply weathered brown biotite
