| 例句 | Some of the trachytic lavas are said to abound with crystals of albite. Narrative of the Circumnavigation of the Globe by the Austrian Frigate Novara, Volume I (Commodore B. Von Wullerstorf-Urbair,) Undertaken by Order of the Imperial Government in the Years 1857, 1858, & 1859, Under the Immediate Auspices of His I. and R. Highness the Archduke Ferdinand Maximilian, Commander-In-Chief of the Austrian Navy. 2012-01-02T03:00:25.873Z Albite, the sodium felspar, has 68.8 per cent of silica, and the species between this and anorthite are regarded as mixtures of albite and anorthite molecules. The New Gresham Encyclopedia Volume 4, Part 3: Estremoz to Felspar 2011-04-14T02:00:59.373Z Practically all varieties of this mineral from anorthite to albite are known to occur in basalt, but by far the commonest species are bytownite and labradorite. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 3 "Banks" to "Bassoon" It depends on the felspar present—i.e., whether it is orthoclase, oligoclase, or albite—whether the soil will be rich in potash or not. Manures and the principles of manuring Those yielded by orthoclase must generally abound in potash, while albite and labradorite, containing little or none of that element, must produce soils in which it is deficient. Elements of Agricultural Chemistry In chemical composition and in optical and other physical characters it is thus much nearer to the anorthite end of the series than to albite. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 4 "Bulgaria" to "Calgary" Several varieties of albite are distinguished, of which the following may be here specially mentioned. The Project Gutenberg Encyclopedia Volume 1 of 28 There are the feldspars, including albite and orthoclase. Let's Collect Rocks and Shells One of the commonest stratified porphyries is of a green colour, highly amygdaloidal with the various minerals described in the preliminary discussion, and including fine tabular crystals of albite. Geological Observations on South America The albite which the former contains undergoes a rapid decomposition, and yields abundance of soda along with some potash, which is seldom altogether wanting, while the hornblende supplies both lime and magnesia. Elements of Agricultural Chemistry Hence probably it is that the fused albite, which is abundant in the pinnacle, disappears in the streams. Volcanic Islands One common variety was greenish-black, with large crystals of blackish albite. Geological Observations on South America As, however, other species of this genus have lately been discovered to cleave in nearly the same planes with albite, this determination must be considered as only provisional. Volcanic Islands Augite in fragments, in gneiss. —with albite, in lava. Geological Observations on South America Granite is a mixture of quartz, felspar, and mica in variable proportions, and the quality of the soil it yields depends on whether the variety of felspar present be orthoclase or albite. Elements of Agricultural Chemistry This basalt is of a grey colour, and contains many crystals of glassy albite, which become much more numerous in the lower, scoriaceous part. Volcanic Islands In the northern islands, the basaltic lavas seem generally to contain more albite than they do in the southern half of the Archipelago; but almost all the streams contain some. Volcanic Islands The lava of these streams is of similar composition with that of the pinnacle, excepting that the crystals of albite appear to be more comminuted, and the grains of fused augite are absent.
