Scolecite FluorapophylliteEntry/Object ID
2004.1.81Description
Chemical Composition: Fe2O3, Iron Oxide
Crystal System: Monoclinic System
Description: Common Name:Scolecite Fluorapophylite
Group Name: Zeolite
Chemistry: CaAl2Si3O10-3H2O
Location: Wagholi, India
Description:Clear and green crystals growing in different directions thin. Fragile.
PHYSICAL CHARACTERISTICS:Color is clear or white.
Luster is vitreous to silky.
Transparency: crystals are transparent to translucent.
Crystal System is monoclinic; 2/m
Crystal Habits include sprays of thin acicular crystals with slanted terminations. Also occurs in radiating fibrous clusters.
Cleavage is perfect in two directions, prismatic. Cleavage is hard to see due to small crystal size.
Fracture is conchoidal.
Hardness is 5.
Specific Gravity is approximately 2.2 (very light)
Streak is white.
Associated Minerals are quartz, apophyllite, babingtonite, heulandite, stilbite and other zeolites. .
Best Field Indicators are crystal habit, hardness, density and associations.
Fracture: conchoidal
Hardness: 5 Apatite
Luster: Vitreous
Occurrence: It forms in volcanic bubbles called vesicles along with other zeolites. Scolecite's sprays of radiating crystals are, well . . . , exotic, inspiring, awesome, magnificant
Notable Occurrences include Poona, India; Riverside Co., California; Iceland; Skye Scotland and Santa Catarina, Brazil
Specific Gravity: 2.2
Streak: white
Variety: Scolecite, a calcium zeolite, natrolite, a sodium zeolite, and mesolite, a calcium and sodium zeolite, are closely related and sometimes found together. The presence of calcium in two of the minerals slightly alters the structure from that of natrolite; from an orthorhombic symmetry to a monoclinic symmetry. However, twinning of scolecite and mesolite often make them look orthorhombic All three minerals are referred to as "chain" or "needle" zeolites. They are similar and hard to distinguish when in clusters with radiating, acicular habits. Natrolite tends to forms thin crystals with pyramidal terminations, but mesolite's fibrous crystals are usually the thinnest crystals of the three minerals. Scolecite's larger crystals tend to be more robust and durable. These characteristics are only generalities and can not be used as dependable identifying traits. Absolute identification can not be made by ordinary meansCollection
