It remains then to consider the means by which the course of the conquering Susquehanna may have been subsequently changed from the lowlands on to the two Pocono synclinesthat it now traverses.
Swatara and Wiconisco synclines (the latter then having gained the Juniata) had been turned aside on their way to the Carboniferous basins.
The several synclines with which the Juniata is concerned have precisely the relative attitudes that are there discussed.
On these lowlands, the headwaters of side streams from other synclines are encountered and a contest ensues as to possession of the drainage territory.
Some will certainly include the location of the Susquehanna on the points of the Pocono synclines under this category; all must feel that such a location savors of an antecedent origin.
On the anticlines were developed the chief streams, and the synclines were left till the last.
The distribution of the coarse varieties coincides closely with the areas of greatest thickness and also with the synclines in which no Weverton sandstone appears.
They have been formed from the overthrown and drawn-out anticlines of great crust-folds, whose synclines or roots are traceable to the south side of the Rhone Valley.
The Juras are an example of the stage of early youth, in which the anticlines still persist as ridges and the synclines coincide with the valleys; this they owe as much to the slight height of their uplift as to the recency of its date (Fig.
Under long-continued erosion, anticlines may be degraded to valleys, while the synclines of the same system may be left in relief as ridges (Fig.
Under long-continued erosion, anticlines may be degraded to valleys, while the synclines of the same system may be left in relief as ridges.
The Juras are an example of the stage of early youth, in which the anticlines still persist as ridges and the synclines coincide with the valleys; this they owe as much to the slight height of their uplift as to the recency of its date.
The gentler synclines and anticlines of the earlier part of the period became accentuated, giving rise to pronounced mountain ridges, right across Europe.
Traced eastward into north Germany, Thuringia and Silesia, the limestones pass into the detrital culm formations, which owe their existence to a southern uplifted massif, the complement of the synclines already mentioned.
Anticlines or synclines whose limbs have about the same inclinations are known as upright or symmetrical folds.
Indicate by arrows the direction of pitch of all plunging anticlines and synclines wherever disclosed by changes of dip and strike (43).
Such mountains are, in fact, much more likely to rise over synclines than upon the site of anticlines.
In the Rocky Mountains proper no eruptive rocks have broken through, so that no ore deposits of importance are known from them, but in the Cretaceous synclines which they enclose valuable coal basins exist.
As might be expected, roughly alined synclines intervene between the anticlines, but are not shown because of space limitations.
The ridge also marks the south edge of several minor anticlines and synclines termed by Dane the "Elephant Butte folds.
By Morrison time the supply of salt beneath the synclines seems to have become used up; hence, the anticline stopped rising, and the Morrison and younger formations were deposited across the structures.
These represent the original anticlines and synclines of mountain-ranges, which in course of time are carved out, as explained above, until the synclines become hills and the anticlines valleys.
These wave-like ridges of the Jura are being slowly worn down; and the time must come when they will be carved out into valleys, while the synclines between them will stand out as hills.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "synclines" in a variety of sentences. We hope that you will now be able to make sentences using this word.
