Introduction

Bristol is a city and a county of England that is extended in the south from Wells to Tortwood in the north. The paper focuses on the analyzing and reflecting on geological aspects of the city of Bristol and to identify the geological significance of this piece of land. Bristol district is a historical piece of land reforms and natural landscape shifts which have been observed by the forefathers of this discipline. Unique mine work and rock structure makes this place a piece of art as illustrated through figure 01. The diagram is inclusive of the Bristoland Somerset coal fields and the Mendip Hillsand. This area has been covered by 1:63,360 BCG's special scale map of the district of Bristol. Rocks of Bristol and its surrounding areas are comprised of Silurian and Cambrian sediments at the location of Tortworth, upper and Lower Carboniferous rocks and old red sandstone's Devonian.

The foreland thrust belt of the Bristol-Mendip has been interpreted in terms of piggy-back and thin skinned thrust belt of Variscan age that is being dominated by the northward transport system. In this thrust, south to north movement is being identified as a dominant direction and the far-travelled klippen's existence has provided the evidence of this thrust belt's skinned nature. In Bristol coalfield, the estimated Dinantian sequence in totality is being found around 800 m thick. Nomenclature's lithostratigraphic scheme which involves Carboniferous units, proves to be more feasible when geologists are cross referring stratigraphy's fault cut-offs.

Discussion

Geology or the science of rock and solid earth has earned a tremendous attention of the international research studies and forums. There are numerous places in the world which are bestowed with natural treasure in the shape of various rocks, landscapes, pebbles, and stones. However, past few years in this discipline have drawn significant emphasis on exploring geological distinctions of the Bristol district which is blessed with numerous hill and mountain structures that are spread across the region. These natural resources and mining work in the area has made Bristol valley a hub of exploring geological aspects and to observe the practical implications of geological theories.

Statistics indicate that Bristol area is composed of around 300 plants and 70 bird species in the New Cut and Harbour areas of Bristol. Eastern side of the district is filled with heathland plants at the stop of Troopers Hill. District of Bristol has been named as a complex geological area that has been giving surprising features like the Cotswold escarpment and genteelly rolled scenery around the surface of Saltford.

A geological cross section of Kingswood area will reveal sandstones and coal layers that were being horizontal 300million years ago when they were being laid down; however, since then these had been eroded and buckled (figure 02). One can easily see thin layers of milestone and mudstone, which were being formed in the Jurassic age (200 million years back) in the areas of Saltford and ...
