A Step-by-Step Guide to Understanding the Geological Map of Great Britain
Step 1: Know What Geological Mapping Is
A geological map is a visual representation of how rock formations are distributed across a specific area like Great Britain. The UK’s geology comprises over 3 billion years of Earth’s history that spans six main periods namely: Cambrian, Ordovician, Silurian, Devonian, Carboniferous and Permian. The maps use color-coding and diagrams to represent these rocks’ age and types.
Step 2: Identify Colors on the Map
Different colors on the geological map indicate different geological materials or features such as sedimentary deposits from oceans or rivers (brown), volcanic ash (gray) or granites (red). For instance;
• Green = beds associated with chalk
• Brown = sandstones
• Pink-red= Triassic rocks i.e., breccia
• Blue-gray= Jurassic limestone that has been replaced by other minerals
Colors range from light shades through to darker colors depending on their origin – which makes them easily identifiable.
Step 3: Look for Symbols & Signs
You will find various symbols showing faults lines-(representing where two blocks crust move past one another), folds-where bedding planes bend towards each other before resuming parallel track -, anticlines (upward fold) syncline (a downward fold).
Each symbol represents many critical things in understanding how land was formed or changed over time due to natural events happening underfoot throughout historical timescales spanning tens or hundreds of millions/billions years old!
An asterisk denotes Site/generation/composition/metamorphosis, while the triangle represents a potential landslip. A letter ‘V’ above patterned lines signifies that this is an outcrop of volcanic rocks.
Step 4: Read The Key
The key is like a decoder ring to help understand everything you’re looking at on the map with explanations for every color and symbol used. There are no shortcuts when it comes to using geological maps – but understanding its fundamental elements will make things easier.
Understanding how various textures, structures, geologic data interconnect could reveal new identifiers assisting in pulling together observations leading towards better resource management or recognizing previously unknown mineral resources!
By following these four steps and being willing to learn about what different symbols mean as shown on Geological Maps of Great Britain countrywide; both professionals (e.g., geoscientists) can use visual representation via shared tools such as apps Geo-Wiki.NL or lithogeochem.com–to identify tectonic shifts accurately/ shape/density patterns yielding ever greater insight into changes occurring deep within our planet Earth!
