Lesson goals

1. You understand which mineral resources can be found in NL and how they are used

2. You can explain why NL depends on other countries for mineral resources.

3. You can use a cross section to explain how and where in NL in the Dutch sub soil gas can be found.

Coal

Crude oil

natural gas

plankton

peat

warm sea

tropical swamp

Carboniferous

Triassic Jurassic Cretaceous

folds & creases due to plate tectonics

open pit mining

offshore platform

Which mineral resources does the Netherlands have? (each answer seperately)

In the depths*    

• Mineral resources that often are mined through shaft mining, drilling and oil platforms

In NL this includes next to fossil fuels, also salt!

Delfstoffen in Nederland

Why did we stop mining for coal in the Netherlands?

Where in the Netherlands do we find natural gas? Study the map carefully and answer precisely

Oil at sea

Remember how oil forms?

To become a reservoir you need a 

• fault
• cap rock / impermeable layer

created by

• plate tectonics

Drag the words to the correct layer

Parent rock

Crude oil

Impermeable layer

Water

Natural gas

Reservoir rock

Parent rock

Impermeable layer

Porous rock that contains the fossil fuel

Rock in which the fossil fuel came into existence

Non-porous layer that stops the gas/oil from escaping

Study the image carefully to answer some questions

In which period did most of the crude oil come into existence?

1. Carboniferous (Late Paleozoic)
2. Jurassic (Mesozoic)
3. Cambrium (Early Paleozoic)
4. Quartenary (Kenozoic)

Use the image in your book, or zoom in

Parent rock

Reservoir rock

Impermeable layer

Carboniferous

oldest matter

Early Permian

Late Permian

Porous

non-porous

salt

sandstone

Ondoordringbare laag zout

 Wordt gebruikt voor productie van chloor > 

PVC, textiel, zeep, keukenzout

Sandstone from the Permian is the... rock for natural gas

1. parent
2. reservoir
3. covering

At the surface    

• Those that are at or relatively close to the surface and can be minder with open pit mining or quarries

* limestone, clay, sand, gravel

Delfstoffen in Nederland

Pleistocene

remember 2nd year?

Gravel and sand depostitions 

Give uses for limestone, sand, clay, gravel

Waar in Nederland komt veel kalksteen aan de oppervlakte voor?

De kalksteen mijnen in Limburg waren/zijn een voorbeeld van

1. Dagbouw
2. Schachtbouw

Wat wordt er als laatste neergelegd door rivieren?

1. stenen
2. grind
3. zand
4. klei

Waarvoor kan zand, grind en klei
gebruikt worden?

Is Nederland voor delfstoffen afhankelijk van het buitenland?

1. ja
2. nee

Afhankelijkheid van het buitenland

• Nederland importeert delfstoffen die wij niet zelf kunnen delven (o.a. 'kritieke mineralen en fossiele brandstoffen). 
• Om de afhankelijkheid van het het buitenland te verkleinen streeft Nederland naar een circulaire economie.

Wat is een circulaire economie?
