Exercise 1 -

A Bay on an Island with Seaward Dipping Strata

Question and Exercises - Cliff Overview - 1

Question-Exercises - Cliff medium close - 2

Question-Exercises - Cliff medium close - 2

Exercise :

You have landed on the south coast of this island, not exactly a desert island, and intend to investigate the nature of the strata, their origin and approximate age. A good cliff section in a stony bay shows beds of debris with wedge-bedding dipping seaward. You immediately notice that this brown material is very poorly sorted. Your first reaction is that it looks like a debrite. The dip seems close to the natural angle of repose, so you soon suspect that it is depositional and not tectonic. Another clue is that the wedging thins out up-dip. In some respects it resembles a huge scree deposit.

You notice that there an vertical intrusion extending up from the below the beach, and this maintains a fairly constant width. It has a knee-bend some way up from the beach. You walk up to this and have a closer look. The grey colour, the type of jointing and the manner in which this cuts across the country rock enables you to quickly recognise just what this is!

The grey rock seems fairly fine grained. An unusual aspect for an intrusion like this is the presence of vesicles. Obviously the pressure was rather low, and because they are not filled (amygdales) this rock probably is fairly young. The lack of hard lithification and jointing in the country rock confirms this. The low pressure shows that there was no deep burial, so not much, if any, strata has been eroded away.

After this cursory examination we now know just what we are dealing with, but need confirmation and more detailed study.

Now write a brief essay on the geology of this locality. Name the rock types present, comment on the chemical composition (and if possible relation to plate tectonics), and probable ages.

(You may be able to suggest just where this is, but this is optional)

Exercise 2

- History of British Oil Exploration -

Reynolds Rides Out on His Grey Horse and Discovers Oil - but - Where?


Question-Exercises - Petroleum exploration by the British in about 1908 - but where?

Question-Exercises - Petroleum exploration, the chief engineer and geologist, G. B. Reynolds, rides out on a surveying expedition

Question-Exercises - Petroleum exploration, successful drilling for oil in 1908 into permeable limestone under anhydrite and on the crest of an anticline

Question-Exercises - Petroleum exploration, the Gach Saran Anticline - but where is it?

Question-Exercises - Petroleum exploration, drilling for oil in the late 1920 - but where?

Oil had been discovered in Pennsylvania by the drilling of a well by Edward L. Drake in 1859. It was very much later that Britain was exploring for oil in a totally different region. An impetus were the plans of Winston Churchill to change the British Naval ships from coal-burning to oil-burning. An English financier who had already made a fortune from gold mining, decided to finance oil exploration in a certain region of the world, an empire, for which he obtained (from the emperor) the exclusive rights to all oil, natural asphalt, ozocerite etc., theoretically for sixty years. He did not personally participate in the exploration but formed an exploration company with his name. He sent his geologists and, in particular, his Chief Engineering - G.B. Reynolds (shown above), out on horseback into particularly promising area, within the empire for which he owned the rights. They searched for years in a region was well-known for oil seeps, natural fires and the Zoroastrian religion.

In 1908 the explorers constructed drilling derricks and struck oil, as shown above. Development in the region then became more rapid as a major oil company took over the initial exploration company. Pipelines were constructed over difficult terrain and a major oil refinery was built in the country, near a river and the coast. Then for many years there was continuing and huge export of oil by sea to a new port and oil refinery in South Wales. This was Britain's main source of petroleum and petroleum products.

Questions :

1. Where is this region of former British oil discovery and production?
2. What is the name of the site of the first major oil discovery in the region?
3. What is the name of the Tertiary evaporite seal?
4. What is the name of the reservoir rock formation?
5. What was done with the associated gas?
6. What was the name of the initial petroleum exporation company?
7. What was the name of the major British oil producing company which took over and operated here until 1951?
8. Why did the initial exploration company turn its attention, at a later date (1936), to Dorset and Hampshire in southern England?

Groundwater Problems

Groundwater exercise for students, hypothetical, regarding a Dorset coastal area

The above map is based on a real locality, but it is an old and inaccurate map and it has been modified for the sake of a simple student exercise. It does not show an accurate real situation and there is no indiction that a waste disposal site could be or would be located in this area. It is for training purposes only. For serious investigation of the area commence with the modern Bridport Geological Map, 1:50,000, Sheet 327 and read the BGS Memoir, Geology of South Dorset and Southeast Devon and its World Heritage Coast. After this introductory reading, it would be necessary to obtain technical specialist data from BGS and water companies, much of which is not publicly available.

Students using the above map should be able to visualise the topography of the area and the geology of the area in three dimensions. Dips and strikes and fault structures can be easily seen and easily visualised. It is obvious which stratal units are permeable and which are not. If this information is considered by mental visualisation there is no need to make any drawings or constructions. The approximate thicknesses of impermeable clays at each locality can be visualised and places with permeable or only thin impermeable strata should be avoided in case of failure of protective barriers against leakage of leachate (undesirable fluids seeping from the waste tip).

The map does not show potentiometric contours or flow lines but in general terms they can be visualised from the topography, once the geology has been understood. None of the sites are ideal but some are better than others. Be sure to consider conservation and environmental aspects, including the Jurassic Coast World Heritage Site.

The problem map is simple and can be answered verbally within twenty minutes by a student with basic geological training. An inexperienced student, or someone lacking in 3-dimensional imagination, might have to use graph paper and draw sections. This would require much more time, perhaps about an hour. It would be good to follow this exercise, based on old and hypothetical information, by a study of the lastest, modern BGS geological map of the area, Bridport Sheet 327 (hint - look at the Kellaways Formation).

Disclaimer: Geological fieldwork involves some level of risk, which can be reduced by knowledge, experience and appropriate safety precautions. Persons undertaking field work should assess the risk, as far as possible, in accordance with weather, conditions on the day and the type of persons involved. In providing field descriptions and guides on the Internet no person is advised here to undertake geological field work at any specific place or in any way that might involve them in unreasonable risk from cliffs, ledges, rocks, sea or other causes. Places need not be visited and the descriptions and photographs here can be used as an alternative to visiting. Individuals and leaders should take appropriate safety precautions, and in bad conditions be prepared to cancel part or all of the field trip if necessary. Permission should be sought for entry into private land and no damage should take place. Attention should be paid to weather warnings, local warnings and danger signs. No liability for death, injury, damage to, or loss of property in connection with a field trip is accepted by providing these websites of geological information. Discussion of geological and geomorphological features, coast erosion, coastal retreat, storm surges etc are given here for academic and educational purposes only. They are not intended for assessment of risk to property or to life. No liability is accepted if this website is used beyond its academic purposes in attempting to determine measures of risk to life or property.
