All are normal dia- base, without olivine, and with an almost colorless augite. The vesicles are mostly lined with cpiartz, and filled with chlorite, sometimes with hornblende. The chlorite is very often spheru- litic and shows the beautiful Berlin-blue polarization color. Secondary growths of a mineral which seems to be plagioclase are known; it is not twinneil. but ai)pears to be sometimes opti- cally continuous with the feldspar rods around the vesicle. It * Trims.
