Examples
-
When I was on the spot the former appeared to me to have some analogy with zechstein, or Alpine limestone; the latter with Jura limestone; I even thought that the granular gypsum of Guire might be that which belongs in Europe to zechstein, or is placed between zechstein and variegated sandstone.
-
Now those names cannot remain the same if, after further examination, the objects of comparison have not retained the same place in the geologic series; if the most able geologists now take for transition-limestone and green sandstone, what they took formerly for zechstein and variegated sandstone.
-
These formations, perhaps, pass from one to the other, so that the latter may be only an upper shelf of zechstein.
-
The zechstein of Europe also contains a very quartzose sandstone.
-
There is in Venezuela a suppression of the different strata which, in the old continent, separate zechstein from Jura limestone.
-
The alpine limestone and the zechstein, famous among the geologists of Freyberg, are identical formations.
-
Cuchivano the alpine limestone contains beds of marly clay, * three or four toises thick; and this geological fact proves on the one hand the identity of the alpenkalkstein with the zechstein of Thuringia, and on the other the affinity of formation existing between the alpine limestone and that of the Jura.
-
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.
-
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.
-
The gem-salt oscillates from zechstein to muschelkalk. (d)
