Understanding geological maps

tutor: Mike Horne FGS

for the Centre for Life Long Learning

University of Hull

This course ran in 2001, 2005, 2008 and 2011.

  We can get an enormous amount of information from a geological map:
 -  where to find different types of rock and their fossils
 - a greater understanding of landscape
 - predictions of structures and rock types at depth
 - discover the geological history of an area
This course will show you how a geological map is made, what all the symbols mean, how to draw a cross section and how to unlock the information from a two dimensional plan to get a four dimensional understanding.

The key to understanding geological maps is being able to think in four dimensions


The course offers the opportunity to study the geological maps in the University's collection.

Content:
The "rock cycle",
The laws of 'superposition' and 'cross cutting relationships'
Introduction to stratigraphy and  structural geology.
How to make a geological map
Symbols used on geological maps
Drawing a topographic cross section
Use of dip and strike in creating a geological cross section
Unraveling the geological history of the area on a map
Prediction of geology at depth
Drawing a geological cross section
A half day field trip to see the effects of the geology on the landscape
.
(The tutor will try to include other related items of interest to the class.)

 

This course is for those interested in Earth Sciences, geology, stratigraphy, soils and landscape interpretation.
Students on previous courses have requested a course on this topic.
Previous experience would be an advantage - students are welcome to contact the tutor to discuss suitability

Students will be asked to interpret the geology shown on the maps provided, describe the geological history of the area and draw cross sections from cartoon and real geological maps. These will be used for the assessment.

Fieldwork excusrion.

Travel from Hull via Cottingham and Skidby over the Yorkshire Wolds to the North Cave Wetlands. There we will see gravels over Lower Lias Clays. From there travel to South Cave Station Qauarry to see the Kelloways Rock, Kelloways Sand and Oxford Clay. Then to Sands Top Quarry at Newbald. The to Rifle Butts SSSI and the Kiplingcotes Valley.

The aim of the excursion is to try to relate the geology we see on the map to the landscape.
