Possibly this was the time of exhumation of the Augenstein peneplain in the Northern Calcareous Alps, formed during Priabonian-Early Kiscellian time. |
|
Most of the region is a sanded-over peneplain with a gradual downward slope from north to southwest. |
|
The Early Mesozoic marine Lower Muschelkalk was deposited on an almost perfect subhorizontal peneplain. |
|
The topography in the Nkamouna area comprises an ancient, undulating peneplain incised by the local streams and rivers. |
|
Two main types of landscape exist in Burkina Faso: the greater part of the country is covered by a peneplain. |
|
The peneplain is deeply incised around its margins and has a remarkably flat interior lying at about 450 m asl. |
|
The region is part of the Appalachian peneplain, which is composed predominantly of a mix of late Precambrian sedimentary and volcanic rocks. |
|
With the older and more resistant rocks of the Precambrian peneplain, these form a low, picturesque coastline of sandy bays and rocky promontories. |
|
It is divided into a large number of physiographic units, the physiography being dominated by a well-developed peneplain that is generally highest in the northwest and slopes gently southeastward to the ocean. |
|
The high mountain surface is a slightly undulating peneplain dissected by rivers, the courses of which were deepened, widened and scoured 20,000 years ago by the glaciers of the last Ice Age. |
|
In the southeast, the peneplain cedes protagonism to the more rugged terrain of the Sierra Morena, with picturesque river valleys and forested mountainsides that form excellent hunting grounds. |
|
The land is elevated, forming parallel upland ranges facing south-east to north-west, and areas of peneplain, the surface of which is igneous rock. |
|
Crosscutting relationships between these re-exposed and tilted peneplains and a third peneplain, an epigene and horizontal plain with residual hills, demonstrate that the latter is younger and thus of post-Cretaceous age. |
|
Paralell with volcanism a hilly peneplain formed in northeastern Scania due to weathering and erosion of the basement rocks. |
|
Surrounding the basin on all of its sides, except in the east, is the dissected Precambrian peneplain, which rises to elevations of 500 to 1,000 feet above sea level and contains several distinct ranges as high as 2,000 feet. |
|
It is a peneplain, the mountainous Paleozoic foundation of which had already been worn down into an undulating plain by the beginning of the Mesozoic Era, beginning about 250 million years ago. |
|
The Cairngorms were formed 40 million years before the last ice age, when slight uplift raised an eroded peneplain based on an exposed granite pluton. |
