About Spilite
Name:
The name was given by Brongniart in 1827. Adj: spilitic.
An altered basic to intermediate, volcanic or subvolcanic rock in which the feldspar is partially or completely composed of albite and is typically accompanied by chlorite, calcite, quartz, epidote, prehnite, or other low-temperature hydrous crystallization products.
Usually an altered basalt, characteristically amygdaloidal or vesicular, in which the feldspar has been albitized and is typically accompanied by chlorite, calcite, epidote, chalcedony, prehnite, or other low-temperature hydrous crystallization products characteristic of a greenstone. Spilite often occurs as submarine lava flows and exhibits pillow structure.
