Landform of the region

Extracts from this document...


Landform of the region The geology of the long Mynd has changed dramatically over the last 920 million years ago. 920 million years ago the long Mynd was full of volcanoes, when the volcanoes had died off and were no longer active, they were formed into mountains. The surrounded sea was full of deposited sediment which had came off the eroding mountains near by. The wrekin is the remains of the ancient volcanoes. ...read more.


By 870 million years the mountains were at the bottom of the sea this is referred to as pre-Cambrian. Between the years of 830-790 million years there was a lot of deposition, which was taking place under sea. The remains of the mountains had, had the water squeezed out leaving behind hard rocks such as sandstone, conglomerates and shales. This picture shows further eroding in the mountains and sandstone and other forms of rocks starting to develop at the bottom on the bottom of the sea. ...read more.


The mountains have now formed into two little stumps after a long period of eroding This picture shows the mountains that have eroded even more to two little stumps, next to the dry land, which were made from the sediments of the mountains. To the west of the west of the Wrekin the sedimentary couldn't be bent anymore and broke this is now called the church stretton rift valley. The Wrekin has weathered down even more to two little faults, the rift valley dropped and the other was worn away. ...read more.

    I found that the fieldwork was hard in most places. I found this fieldwork enquiry quite enjoyable because I found out a lot of information I didn't know about footpath erosion, like there are only 6 - 8 inches of vital topsoil in most of the world, and erosion is making that less.

    - Physical Weathering: break up of rocks by processes such as freeze thaw which do not alter the minerals which form the rock. - Weathering: The breakdown of surface rock by weather without any surface movement. - Solution: a form of chemical weathering.

  2. Investigate the relationship between the solid geology and the physical landscape from Ingleton to ...

    Comparisons between diagrams/photographs and the documented work from the field study, with the evidence, already collected from a geologist, there are certainly some similarities. For example at Pecca Quarry/Falls, the presence of the North Craven fault provides strong evidence as to why the Upper Ordovician shale gives way to the Lower Ordovician slates and sandstones.

    Big holes in the ground. Methods of Analysis Comparing the fossils found with known outcrops of Carboniferous Limestone, it will be possible to give a small idea about what has happened to the Carboniferous Limestone. The fossils will show if the environment was right for the deposition of the limestone in the Carboniferous period.
