Definitions
American Heritage® Dictionary of the English Language, Fourth Edition
- n. Any of a series of variously colored, often fluorescent mineral silicates of aluminum, calcium, and sodium. Also called wernerite.
Century Dictionary and Cyclopedia
- n. One of a group of minerals, silicates of aluminium and calcium, with sometimes sodium, also often containing chlorin in small amount. They occur in tetragonal crystals, and also massive, of a white to grayish, yellowish, or reddish color. They are named mionite, paranthine, ekebergite, dipyre, marialite, etc. The species show something of the same progressive change in composition observed among the triclinic feld-spars, the increase in amount of soda (from mionite to marialite) being accompanied by a corresponding increase in silica.
Wiktionary
- n. Any of several mixed sodium and calcium aluminosilicates which also contain chloride, carbonate and sulfate and are found in metamorphic rocks
GNU Webster's 1913
- n. A grayish white mineral occuring in tetragonal crystals and in cleavable masses. It is essentially a silicate of alumina and soda.
Etymologies
- Latin scāpus, stalk; see scape1 + -lite (from the prismatic shape of its crystals).
Examples
“The south-western group consists of metasediments, charnokites and scapolite-bearing calc-granulites, while the highland group comprises khondalites of metamorphosed sediments and charnokites.”
“Most significant is the presence of the Sinharaja Basic Zone, consisting of hornblende, pyriclasts, basic charnokites, pyroxene amphibolites and scapolite-bearing calc-granulites and blended with small amounts of quartzites, garnet-biotite gneisses and intermediate charnokites.”
“The severe crushing to which the rock has been subjected has resulted in the conversion of the plagioclase into scapolite and also in the formation of zoisite by the characteristic alteration of the lime bearing silicate of the feldspar in conjunction with other constituents of the rock.”
