Figure 8 shows that the unnamed upper member of the Hermosa Formation and the overlying Cutler and Moenkopi Formations are thickest beneath the Courthouse syncline but wedge out against the flanks of the anticline.
A section across the Salt Valley anticline and the Courthouse syncline in the northwestern part of the park is shown in figure 8, and the axes of these structures are shown in figure 9.
About 2 miles northeast of the bridge, we cross the axis of the Courthouse syncline (fig.
The location of the successful lateral stream on one or the other side of the syncline may be determined by the dip of the beds, gaps being cut quicker on steep than on gentle dips.
They have departed from the axis of theirsyncline to the softer beds on its southern side; FE of fig.
Consider two side streams of this kind, C and D, heading against each other at E, one joining the main stream lower down the axis of the syncline than the other.
The further southwestward extension of the Pocono sandstone ridges in the southern than in the northern syncline gives further illustration of this peculiarity of form.
A stream flowing along a syncline of hard beds (Carboniferous sandstones) develops side streams which breach the adjacent anticlines and open lowlands in the underlying softer beds (Devonian and Silurian).
All of these examples are truly only special cases of the one already described in which the Juniata left its original syncline for others to the south.
In the case of the former each bed has a tendency to slip or slide away from the axis, while in a syncline it is just the reverse--the strata being inclined towards and not away from the axis.
It will be also noted that Glen-Lyon coincides neither with a syncline nor a fault; it has been eroded along the outcrops of the strata.
Hence the anticline noses out to the north and the syncline to the south.
Thus we find that the ocean floor is depressed into a syncline along the western coast of South America; a trough always parallel to the ranges of the Andes.
When folding at length takes place along the axis of the elongated syncline of deposition, the stresses find relief probably for some hundreds of miles, and the region of folding now becomes compressed in a transverse direction.
Farther south, the trail swings west of Lockhart Basin, whose center exposes part of a syncline (fig.
If the rocks are dry, then the chief points of accumulation of the oil will be at or near the bottom of the syncline (downfold), or lowest portion of the porous bed.
The Cambrian rocks of North Wales occur in two complex anticlines, separated by an intermediate syncline of Ordovician strata occupying the Snowdonian hills.
The Mendip system is well shewn in the Mendip Hills, but the remains of a still more important anticline are seen in South Devon and Cornwall, separated from the Mendip Hills by the great syncline of Devon.
Strictly speaking, a structural basin is formed of rock beds which exhibit a centroclinal dip; an elongated narrow syncline or trough is not a basin.
Faults crossing folded strata cause the outcrops to approach on the upthrow side of a syncline and tend to separate the outcrops of an anticline (figs.
Plan of an anticline (A) and syncline (S), dislocated by a fault.
This was accompanied by further downwarping in the syncline to the east of the fault and the erosion of uplifted sedimentary rocks on the west side of the fault (Fig.
Because the Wasatch Formation immediately underlying the Fossil Butte Member of the Green River Formation in the Fossil Syncline Basin is Lysitean (mid to early Eocene), it is probable that the fish deposits are of Lostcabinian age.
Superficially, the Fossil Basin appears to be a broad syncline with tilted beds dipping sharply or gently basinward from the basin margins.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "syncline" in a variety of sentences. We hope that you will now be able to make sentences using this word.
