Igneous Rocks

Igneous Rock Specimens – Available Online

At Northern Geological Supplies Ltd, we are proud to offer a wide range of geological igneous specimens sourced from numerous localities all over the world.

What are Igneous Rocks?

Igneous rocks form from the cooling and solidification of magma or lava. Extrusive igneous rocks cool at the surface with smaller crystals, while intrusive igneous rocks form deep within the Earth with larger, well-formed crystals known as phenocrysts.

A Wide Range of Rocks to Suit Your Needs

Our supply ranges from common specimens such as granite, basalt and pumice, to more unique pieces collected from type localities such as Preseli bluestone or Rapakivi granite. Each specimen can be enjoyed by both experienced collectors and amateur enthusiasts.

Efficient Storage Solutions for Your Specimens

Every specimen comes in a white card tray with an information label. Our labelled igneous rock specimens can be easily housed in our brown outer boxes, with each box holding 35 of our 2 x 2 inch card trays.

A Trusted Supplier of Igneous Rocks in the UK

Northern Geological has a long history of supplying the educational sector with educational igneous rock kits and classroom igneous rock packs.
