Examples
“They form a large class of minerals of which Thomsonite and natrolite may be selected as examples --”
“The bed holding the upright crystals is also natrolite in confused matted masses.”
“It generally occurs in the form shown in Fig. 9, grouped very similarly to natrolite, and being right upon the rock or a thin bed of itself.”
“Stilbite is characterized by its form, difficult gelatinizing, and intumescence before the blowpipe; from natrolite as mentioned under that species.”
“-- Small quantities of this beautiful mineral have been found in Shaft No. 2, in a small bed of but a few square feet in area, but quite thick and appearing much like natrolite.”
“There is, however, a very fine vein of pectolite about twenty-five feet further east from the natrolite bed; it runs from the floor to ceiling, and is about two inches in thickness; some specimens of which I took from these were unusually unique in both size and appearance.”
“This natrolite is a grouping of very small but perfect crystals, having the forms shown in Fig. 5; they are from a quarter to an inch long, and, if not perfectly transparent, are of a pure white color; they may be readily recognized by their form, and occurring in this bed.”
“Pectolite sometimes resembles some of the others, but may be readily distinguished by its _tough_ long fibers, not brittle like natrolite.”
“Ekkehardt furnishing an occasion for a visit to the Hohentwiel mountain in search of that golden-tinted natrolite mineral, which was duly found”
“On the atomic level deformations in the auxetic zeolite natrolite”
