Kaynak: Crystal habitBainite is an
acicular microstructure (not a phase) that forms in steels at temperatures of 250–550 °C (depending on alloy content First
Kaynak: BainiteFrostwork is a type of speleothem (cave formation) composed of
acicular ("needle-like") growths almost always composed of aragonite (a
Kaynak: FrostworkNeedle stone or needle-zeolite are other informal names, alluding to the common
acicular habit of the crystal s, which are often very
Kaynak: NatroliteIndividual crystals are rare but do occur as slender to
acicular prisms. Pseudomorph s after more tabular or blocky azurite crystals
Kaynak: MalachiteCrystals of brochantite can range from emerald green to black-green to blue-green, and can be
acicular or prismatic. Brochantite is
Kaynak: BrochantiteAragonite's crystal lattice differs from that of calcite, resulting in a different crystal shape, an orthorhombic system with
acicularKaynak: AragoniteIt is brassy in colour and has an
acicular habit, often forming radiating masses and furry aggregates. It can be distinguished from
Kaynak: MilleriteIt occurs in tabular,
acicular, or fibrous crystals with a vitreous luster. Originally believed to be a rare mineral, antlerite was found
Kaynak: AntleriteCrystals are short prismatic parallel to the c axis and often
acicular . Calcium -rich varieties often show steep pyramidal forms.
Kaynak: Strontianitemineral with formula Ca 2(SO 4)(CO 3)·4H 2 O. The mineral is white to colorless and occurs as groupings of
acicular (needle-shaped) crystals.
Kaynak: RapidcreekiteEpsomite crystallizes in the orthorhombic system as rarely found
acicular or fibrous crystals, the normal form is as massive
Kaynak: EpsomiteIt occurs as prismatic to
acicular transparent yellow to white orthorhombic crystals. It occurs in the oxidation zone of mineral
