Longhoughton Quarry facts for kids

Longhoughton Quarry is a special place in north Northumberland, North East England. It's called a Site of Special Scientific Interest (SSSI). This means it's protected because of its unique natural features. The quarry used to dig up a very hard, dark rock called whinstone. This rock is often found with a large rock formation in Northumberland called the Whin Sill.

Exploring Longhoughton Quarry

Longhoughton Quarry is located about 0.9 miles (1.4 km) west of Longhoughton. This is a small village right by the coast in Northumberland. The special protected area of the quarry covers about 6.7 hectares (16.6 acres).

What Makes the Rocks Special?

This quarry is amazing for learning about how rocks are formed! You can see where hot, melted rock pushed its way into older rock layers. This process is called an "intrusion."

The quarry shows a type of igneous rock called dolerite. Igneous rocks are formed when hot, melted rock cools down and becomes solid. Here, the dolerite pushed into layers of a rock called "Great Limestone."

You can also see how the hot rock changed the rocks around it. Sometimes, pieces of the older rock got mixed into the new, cooled rock. The heat from the melted rock also "baked" the surrounding rocks, changing their appearance. Scientists can even see signs of ancient rivers or streams that once flowed through the area.

In 2009, experts checked on Longhoughton Quarry. They found that its special natural features were in good condition.
