Sandstone

Sandstone is very commonly found around the Taroona Foreshore and is one of the most common sedimentary rock types in the world. Sandstone is generally a grainy, layered rock although when weathered it can become compacted and smooth. Sandstone is orange-brown in colour and is made up of tiny rock fragments and different minerals from other rocks, which is why it is considered sedimentary.

Dolerite

One of the main types of rock in the Taroona foreshore is Dolerite. Dolerite is a hard, grey-black rock, with interlocking crystals inside which are visible when looked at up close and show that Dolerite is igneous. Igneous rocks are formed by magma from volcanoes, which means that there used to be volcanic action around Taroona millions of years ago.

Above: An example of Dolerite found on the Taroona foreshore. This example of Dolerite is slightly discoloured because of the growth of plant and animal matter.
