It is the ancient gypsum of secondary formation of Werner's school (alterer flozgyps), which we almost preferably call muriatiferous gypsum. ❋ Alexander Von Humboldt (1814)
It is the ancient gypsum of secondary formation of Werner’s school (alterer flozgyps), which we almost preferably call muriatiferous gypsum. ❋ Unknown (1851)
[* Magnesian limestone is of a straw-yellow colour, and contains madrepores: it lies beneath red marl, or muriatiferous red sandstone.] ❋ Unknown (1851)
To class it according to the type of European formations I would range it among the gypsums, often muriatiferous, that cover the Alpine limestone or zechstein. ❋ Unknown (1851)
The earth already lixiviated is never carried away here, as it is from time to time in the island of Margareta; nor have wells been dug in the muriatiferous clay, with the view of finding strata richer in muriate of soda. ❋ Unknown (1851)
Penas Negras rests on a slate-clay, mixed with quartzose sand; but there is no proof of the muriatiferous clay of the salt-works being of more ancient formation than this slate-clay, or of its alternating with banks of sandstone. ❋ Unknown (1851)
It is questioned here, as at Cumana, whether the ground be impregnated with saline particles because it has been for ages covered at intervals with sea-water evaporated by the heat of the sun, or whether the soil be muriatiferous, as in a mine very poor in native salt. ❋ Unknown (1851)
We have already observed, that the muriatiferous clay of Araya contains solid and friable petroleum. ❋ Unknown (1851)
It is true, that for the new salt-work near the battery of Araya, the seawater is received into pits, as in the salt marshes of the south of France; but in the island of Margareta, near Pampatar, salt is manufactured by employing only fresh water, with which the muriatiferous clay has first been lixiviated. ❋ Unknown (1851)
Europe, the Alpine limestone is separated from the Jura limestone by the muriatiferous gypsum; but often this latter is entirely wanting, or is contained as a subordinate layer in the Alpine limestone. ❋ Unknown (1851)
In the same manner as sulphur and coal belong to periods of formation very remote from each other, the sal-gem is also found sometimes in transition gypsum, * sometimes in the Alpine limestone, * sometimes in a muriatiferous clay lying on a very recent sandstone, * and lastly, sometimes in a gypsum* posterior to the chalk. ❋ Unknown (1851)
It is known that the zechstein is situated between the muriatiferous gypsum and the conglomerate (ancient sandstone); or where there is no muriatiferous gypsum, between the slaty sandstone with roestones (buntesandstein, Wern.), and the conglomerate or ancient sandstone. ❋ Unknown (1851)
When we were yet unacquainted with sulphur, except as disseminated in the muriatiferous gypsum and in the Alpine limestone, we were almost forced to the belief, that in every part of the globe the volcanic fire acted on rocks of secondary formation; but recent observations have proved that sulphur exists in great abundance in those primitive rocks which so many phenomena indicate as the centre of the volcanic action. ❋ Unknown (1851)
Directing our course southward, we traversed first the plain covered with muriatiferous clay, and stripped of vegetation; then two chains of hills of sandstone, between which the lagoon is situated. ❋ Unknown (1851)
Horned cattle prosper here without those famous bareros, or muriatiferous lands, which abound in the Pampas of ❋ Unknown (1851)
The muriatiferous gypsum, * whether it be found in layers in the Jura or Alpine limestone, or whether it separate these two formations, or lie between the Alpine limestone and argillaceous sandstone, also presents, on account of its great solubility, enormous cavities, sometimes communicating with each other at several leagues distance. ❋ Unknown (1851)
In order to obtain a clear idea of the geological connection existing between this muriatiferous soil and the rocks of more ancient formation, we shall take a general view of the neighbouring mountains of Cumana, and those of the peninsula of Araya, and the island of Margareta. ❋ Unknown (1851)
It abounds in common clay, which differs essentially from the salzthon or muriatiferous clay. ❋ Unknown (1851)
We shall not question, that sal-gem, either pure or mixed with muriatiferous clay, may have been deposited by an ancient sea; but everything evinces that it was formed during an order of things bearing no resemblance to that in which the sea at present, by a slower operation, deposits a few particles of muriate of soda on the sands of our shores. ❋ Unknown (1851)
We have now to speak of a fourth formation, which probably rests* on the calcareous sandstone of Araya, I mean the muriatiferous clay. ❋ Unknown (1851)
