Description: Original antique lithograph1888Total size including border (approx) 12,6 x 8,5 inches 32 x 21,5 cmThis is not a recent copy or modern reproductionVerso is blankPlate IX.Figs. 1-8. Zeolite minerals.1. Analcim, from the Fassathale in Tyrol, which after theL e u c i t (see p. 22) Deltoidikositetrahedron called leucitoederperforming.2. Natrolite, radially fibrous spherical or hemispherical groups,which are next to each other on fractures of the phonolite coneHohentwiel grew up and in part such gapsor fill in the columns completely. The coloring isgenerally a pale yellow outwardly and in the aggregates often red, concentric colored rings stand out,alternating with pale to white, especially noticeable whensuch masses are cut and polished.3. Natrolite, thin vrismatic crystals formed byan almost right-angled orthorhombic prism, pointedat the ends by a blunt orthorhombic pyramid, as colorless and transparent in bladder spacesto appear grown up; from the Auvergne.4. Stilbit (Heulandit) crystal, combination of the clinorhom bical transverse and longitudinal surfaces with the surfaces of oneHemidoma and the base throat, subordinate to the cursesa hemipyramid.5. Desmin, orthorhombic crystals which represent the combinationthe transverse and longitudinal surfaces with an orthorhombicForm a pyramid and are usually formed so that manysmall by homologous grouping to put the large together. In doing so, the individuals diverge from one anotherLittle, which means that the group is called tuftedwill; from the almond stones of the Faroe Islands.6. Analcim, combination of the hexahedron with the leucitohedron(Fig. 1); the one in Mandelstein of the Seitzer Alpe in TyrolThe grown crystals of this form are usually pale red in color.7. A p o p h y l i t, combination of a square prismwith a square pyramid, which one on thePrism edges straight attached four-faced end taperingforms, at the latter the base surface truncating the end corners.Such crystals, colorless to pale rose-red at Andreas Berg am Harz, colorless to white on the Far 8. The same, tabular by predominant base surfaces,subordinate to the predominant shapes in FIG. 7;from the Fassathale in Tyrol. Figures 9-18. Calcite and aragonite. Calcite, K a l k s p a t h, splitting piece that asBasic shape chosen rhombohedron with 105 ° 5 'Representing end edge angles. 10. Likewise, the combination of the basic shape with a blunt oneRhombohedron, which just blunts the end edges of thosefrom the Münsterthale in Baden. 11. Likewise, the most common scalenohedron, as is the case with manyFindings (e.g. in the Muschelkalke near Cannstadt inWürttemberg) occurs.12.0 Same. pointed rhombohedron, as is often the case with crystalsof calcite in corridors on the Black Forest and inErzgebirge occurs. In this form are also foundthe so-called sandstone crystals from FontainebleauParis, d. H. impregnated with a lot of fine ouarz sandCalcite crystals in sandstone. 13. Lik. Combination of a hexagonal prism with ablunt rhombohedron; z. B. on crystals ofAndreas-Berg am Harz. 14. The same, hemitropic twin of two scalenohedra (Fig. 11),Contact twin with one of the base surfaces parallelAdhesion area. 15. Aragonite, so-called hot spring stone from Karlsbad in Bohemia,sinter-like paragraphs of water, band-shaped after theLayers of heels, striped white, yellow, brown and red.16. Iron flower, stalactitic fibrous aragonite, palebluish-white, coral-like branched, knotty shapesforming, on fissures of the siderite near Eisenerz in Styria.17. Stalactite, a pin of stalactitic lime, imStalky inside, like those in stalactite caves from time to timeof very considerable size, usually paleyellow, also colored to flesh red. 18. Pea stone from Karlsbad in Bohemia, sphericalAragonite, large aggregates composed of spheresforming a heel from warm springs.
