· Crushed dolerite base Method: In wet and moderate areas, there were signs of alteration evidenced by the identification of new secondary minerals in the samples investigated. Secondary minerals (smectites) with high swelling potential and plasticities were already part of the fresh dolerite (control sample).

The crushed dolerite (1889 – 1931) was used as a road stone. It is said that the stone used to build O’Connell Street in Dublin was shipped out of here. The harbour, still home to local fishermen, can get very busy in the summer with recreational boaters.

Diabase (/ ˈ d aɪ. ə ˌ b eɪ s /), also called dolerite (/ ˈ d ɒ l. ə ˌ r aɪ t /) or microgabbro, is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro.Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine-grained to aphanitic chilled margins which may contain tachylite (dark mafic glass).

· One of the most distinct differences between granite and dolerite is their formation environment and cooling history. Granite forms deep within the Earth’s crust, where magma cools slowly over thousands to millions of years, allowing large crystals to develop.

Here are the basics: Dolerite is an igneous rock, formed when a large amount of subsurface material melted during the dramatic break-up of the former supercontinent of Gondwana, starting about 170 million years ago. The resulting magma bubbled and oozed its way towards the earth’s surface, becoming one of the largest upwellings of magma in
