		The SPG is zoned, variably deformed, and the Marko's pegmatite is found in the Mn-rich, petalite zone of the Eastern pegmatite subgroup and is relatively undeformed.
		Petalite replacement by spodumene-quartz intergrowths (squi) is minor and is associated with veinlets of late albite or lithian muscovite.
		The wall zone is composed of beryl-muscovite-albite-quartz and is distinguished from the PCZ by the absence of petalite, and by the presence of a wide variety of oxide phases.

	Pegmatites of the Bridger Moountains, Wyoming
		Lithium minerals, including petalite, lepidolite and amblygonite, were deposited in zones at the centers of several dikes.
		The lithium phase is generally a late hydrothermal stage, but in these dikes the petalite is completely replaced by cleavelandite, so the, lithium phase must be pre-albite in age.
		The minerals, lepidolite, petalite and amblygonite were deposited in a few dikes at this time.

		Petalite was named after the Greek word for "leaf" because its cleavage is perfect, like the veins and junctions in a leaf.
		Petalite crystals are rare and occur mostly as coarse aggregates, but cat's eye petalite has been found.
		Petalite ranks 6 to 6.5 on Mohs' hardness scale; therefore, the gem will work well in necklaces, but is too brittle to be used in rings.
