Synonyms: Granite Butterfly Green, Granito Verde Butterfly, Green Butterfly, Verde Pavao

Location: Butterfly Green granite is quarried at quarry RN 000165, Corrego do Jao, Vila Pavao, Espirito Santo, Brazil.

Description: Butterfly Green granite is a coarse to very coarse-grained, dark grey-green quartz monzonite. This stone internationally may be nominated as a granite and in the area of application of the European Standard this stone must be nominated as a monzonite.

The veining and colour varies considerably and a small sample of Butterfly Green granite may not be representative of the whole slab therefore swatch samples must be approved for large projects to ensure that the blocks are all extracted from the same quarry face for matching purposes. Ideal for both interior and exterior use, Butterfly Green granite is frost free and polish constant.

Monzonite: An intermediate igneous intrusive rock composed of approximately equal amounts of sodic to intermediate plagioclase and orthoclase feldspars with minor amounts of hornblende, biotite and other minerals. Quartz a minor constituent or is absent; with greater than 10% quartz the rock is termed a quartz monzonite. If the rock has more orthoclase or potassium feldspar it grades into a syenite. With an increase of calcic plagioclase and mafic minerals the rock type becomes a diorite.

Quartz Monzonite: (Or adamellite) is an intrusive igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase. Quartz is present in significant amounts. Biotite and/or hornblende constitute the dark minerals. Quartz monzonite porphyry is often associated with copper mineralization in the porphyry copper ore deposits. Because of its coloring, it is often confused with granite, but whereas the mass of granite is 20% quartz, quartz monzonite is only 5-20% quartz.
