Species: | Gonnardite |
Formula: | (Na,Ca)2(Si,Al)5O10 · 3H2O |
Comments: | "The gonnardite/natrolite intergrowth, considered mesolite prior to 1988, has been verified from all Melbourne localities, and occurs as small, opaque white hemispheres and tufts composed of radiating fibres and prismatic needles. The individual groups have diameters up to 6 mm, though typically are 1 to 3 mm. The groups show a variety of lustre-chalky, sub-vitreous or silky- and the prismatic needles appear quite glassy when viewed through the microscope. The clusters that have been studied are radially zoned, presenting a compact gonnargite-rich core and a soft fibrous natrolite-rich outer zone." |
