Quick Answer: Geological Maps of the World is a world geological map that colours the continents, and often the ocean floors, by the age and type of the rocks at the surface, showing ancient shields, younger mountain belts, sedimentary basins and volcanic regions. It is used in earth-science and geography teaching.

Reading the Rocks of a Whole Planet

A geological map shows which rocks lie at the surface and how old they are, and a geological map of the world reveals patterns no local map can. The oldest continental cores, the Precambrian shields of Canada, Scandinavia, Africa, India, Australia and Brazil, sit in the interiors of continents. Younger mountain belts wrap around or between them: the Andes and Rockies along the Pacific margin, the Alps and Himalaya where plates have collided. Wide sedimentary basins fill much of the space in between.

Many world geological maps also colour the ocean floor by age, and here the striking pattern is symmetry: the youngest crust lies along mid-ocean ridges and ages increase on both sides towards the continents. Very little oceanic crust is older than about 200 million years, whereas continental rocks go back billions of years, a contrast that only makes sense with plate tectonics.

Colours on geological maps follow conventions linked to rock age, and the legend is the key to using one. Students should read the legend first, find the colour for a period, and then trace where rocks of that age appear around the world. The listing name is plural, so check whether a single map or a set is supplied.

Applications

Locating the oldest rocks on each continent and discussing why they sit in continental interiors
Comparing mountain belts on the geological map with plate boundaries on a tectonic map
Tracing rocks of one period, such as the Cretaceous, across several continents
Introducing geological legends before students work on a detailed national or local map

Specifications

Map type	World geological map, rocks by age and type
Features typically shown	Precambrian shields, orogenic belts, sedimentary basins, volcanic provinces, ocean-floor ages
Key element	Colour legend by geological period
Level	Secondary earth science and introductory university geology
Number of sheets, size and scale	Confirm at enquiry

Care & Handling

Mount the map low enough for students to reach the legend, since every activity starts there.
Keep it framed or rolled; folds across a geological map make colour boundaries hard to follow.
Keep it out of direct sun, because pale legend colours become hard to tell apart once faded.

Why Choose LabEquip

Earth-science teachers often display this map next to the Plate Tectonic Map World so that rock ages and plate boundaries can be compared directly. National detail comes from the Geological Map of France; both sit in Educational Charts, and orders go through the LabEquip contact page.

Frequently Asked Questions

What does a geological map show that a physical map does not?

A physical map shows relief, rivers and coastlines. A geological map shows the rocks at the surface beneath soil and vegetation, their type and their age, which explains why landscapes and resources are where they are.

Why are the oldest rocks found in the middle of continents?

Continents grew over billions of years as younger mountain belts were added around ancient cores. Those cores, the shields and cratons, have been stable for so long that erosion has exposed rocks formed very early in the earth’s history.

Why is the ocean floor so young compared with the continents?

Oceanic crust forms at mid-ocean ridges and is destroyed at subduction zones, so it is continually recycled. Continental crust is too buoyant to sink, so it survives for billions of years.

How do I read the colours on a geological map?

Start with the legend, which links each colour or pattern to a rock age or type. Similar colours usually mark neighbouring periods, and symbols or letters often distinguish igneous from sedimentary rocks.

Is this a map of plate boundaries?

Not primarily. It shows rocks and their ages, although young mountain belts and ocean-floor ages clearly reflect plate movements. For plate outlines and boundary types, use a plate tectonic map alongside it.

How can students use the map in a lesson?

Give each group a geological period and ask them to find every region where rocks of that age appear, then suggest why. Linking the pattern to ancient seas or mountain building turns map reading into reasoning.
