The few specimens we obtained of its rocks consisted of the different varieties of talcose formation, with quartz and jasper.
In lower Canada and Vermont, it is accompanied by granular limestone and granular quartz, which separate it from the mica slate and talcose rocks on the east.

Only a single piece of iron is required, and, at a pinch, one could even dispense with that by using a slab of talcose material, roughly shaping a hearth therein and making a hole for the blast.
Notwithstanding a general uniformity in the aspect of plutonic rocks, we have seen in the last chapter that there are many varieties, such as Syenite, Talcose granite, and others.
The granite, still remaining unstratified, becomes charged with green particles; and the talcose gneiss assumes a granitiform structure without losing its stratification.
Valorsine, near Mont Blanc, granite and granitic veins are observable, piercing through talcose gneiss, which passes insensibly upwards into secondary strata.
Talcose granite, or Protogine of the French, is a mixture of felspar, quartz, and talc.
When talc takes the place of mica, it is talcose granite.
It is one of the bases of dolomite and magnesian limestone, and is an ingredient of talc and all talcose rocks.
These two component parts are separable in the calcareous and talcose earths; but in the argillaceous and silicious earths they are so intimately dissolved, that they can not be separated from each other.
Of the acids, carbonic acid appears to be alone contained in a free state in vegetable sap; the other elemental and mineral acids are united to alkalies, talcose and calcareous earths.
The silicious, argillaceous, and talcose earths must occupy, from their having been first precipitated, the middle of the planet.
The precipitation of strata is divided also into four formations, into silicious, argillaceous, talcose and calcareous strata, close to which range also the strata of ores, Inflammables and salts.
It may also be said that in the calcareous earth fire, in the talcose earths the air, in the argillaceous earth water has exercised its influence and displaced the Earthy.
There exists, so to speak, a corrosive silicious as also argillaceous and talcose earth.
Its kindred earths are the Glucine and Yttria, verging towards the talcose earths.
Such is the behaviour of the Talcose earths; its minerals are unctuous, fall when exposed to the air into electric lamellæ, and burn brittle.
By granite the silicious principally came out of water, but what was argillaceous and talcose remained behind.
The talcose strata pass by serpentine and potters' stone into steatite and meerschaum.
The first dismemberment of principles is shown by the talcose earth.
This diminishes towards the native pits, and there the vein diverges into two portions, both presenting a decomposed appearance, the casing on both foot and hanging wall having a highly talcose character.
Where talcose it is bluish, and shows streaks of 'black sand,' titaniferous iron.
This hole had been sunk 70 to 80 feet deep in the talcose stone; and it would have been far easier and better to have driven galleries and adits into the face of the rock.
Talcose flakes are frequent, and in some places it seems to be clearly gneiss.
In all the rocks are talcose and show a sort of conglomerate of quartz pebbles, in some cases water-worn and in others angular, bedded in a mixture of quartz and granite detritus.
The manager gave me a small common red flower pot for a muffle, and with the smith's forge (the fire built round with a few blocks of talcose schist) for a furnace, my plant was complete.
Its ore-bed seems to be embraced in a greenish talcose rock.
It is a kind of nephrite or jade, a mineral which usually occurs in talcose or magnesian rocks.
They are micaceous strata; and thus the true cipollino is a mixture of talcose schist with white saccharoidal marble, and may be said to form a transition link between marble and common stone.
Notwithstanding a general uniformity in the aspect of Plutonic rocks, we have seen in the last chapter that there are many varieties, such as syenite, talcose granite, and others.
They were found to be alternate groups of common and talcose slate and of a rock made up principally of angular fragments of white quartz (grauwacke).
The aspect of the rock is very singular in those places where thin plates of black ampelite alternate with thin, sinuous, and satiny plates of a talcose slate as white as snow.
Near San Pedro, the talcose gneiss of Buenavista passes into a mica-slate filled with garnets, and containing subordinate beds of serpentine.
This road is cut out of a talcose gneiss* in a state of decomposition.
Very near the Hato the talcose slate becomes entirely white, and contains small layers of soft and unctuous graphic ampelite.
Immediately at the western base of the Catoctin Mountain, a range of magnesian or talcose slates occur traversing its whole length.
Found in the greenish talcose rocks at Taylorstown.
This intrusive rock, however, does not always reach the surface, but it exists below at no great depth, and is observed piercing through the talcose gneiss, and passing up into Secondary strata.
Protogine is a talcose granite, composed of felspar, quartz, and talc or chlorite, or decomposed mica, which take the place of the usual mica.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "talcose" in a variety of sentences. We hope that you will now be able to make sentences using this word.
