Dolerieten komen voor in die gebieden waar, door de geologische geschiedenis heen, mafisch vulkanisme is ontstaan en wordt gevormd tussen het uitvloeiingsgesteente basalt en het dieptegesteente gabbro.Varianten van doleriet zijn ofiet (voornamelijk tijdens het laat-Trias in de Pyreneeën gevormde doleriet) of diabaas, dolerieten met veel olivijn, waardoor het gesteente …

Diabase is also called Dolerite. Diabase dykes and sills are typically shallow intrusive bodies and often exhibit fine grained to aphanitic chilled margins which may contain tachylite (dark mafic …

Dolerite is a holocrystalline subvolcanic rock equivalent to basaltic volcanic rocks or plutonic gabbro. It occurs as dikes (gangue rocks) and sills (stock dikes). Dolerite usually has a fine but …

Dolerite cliffs by Em Wilson. One of the spectacular features of dolerite, including on Kunanyi/Mount Wellington, is steep columnar cliffs. These are the result of the magma cooling quite quickly, relatively close to the surface, and forming vertical joints. At the edges of dolerite masses these joints have eroded to become spectacular cliffs.

Dolerit, ein in der Literatur uneinheitlich verwendeter Begriff für basaltische bis gabbroide Gesteine; in Mitteleuropa, v.a. in England verwendet für klein- bis mittelkörnige, oft subvulkanisch entstandene Basalte, in denen nicht geregelte, leistenförmige Plagioklaskristalle in einer Grundmasse aus Augit eingebettet sind (ophitisches Gefüge). ). In Amerika und Skandinavien …

Dolerite sills Associated with the vast outpouring of lava there was a huge deep plumbing system of molten rock, called magma. Magmas originated by melting at depths of 100 km inside the Earth, and infiltrated their way upward to surface. Any joints, cracks or weaknesses in the Earth's crust would have been exploited by invading magma.

Dolerite also provides important information about the Earth's deep interior. The minerals that make up dolerite are stable at high pressures and temperatures, and can provide clues about the conditions that exist in the Earth's mantle. Famous Dolerite Formations . Dolerite is a common rock type, and can be found in many parts of the world.

La dolerita o diabasa, comúnmente conocida como «granito negro» es una roca ígnea intrusiva de granulado fino a medio, con muchos cristales de color gris oscuro o negro. Su composición mineralógica es casi idéntica a la del gabro, pero habiendo superado una situación filoniana o subvolcánica. El nombre diabasa deriva del griego διὰ = a través de βάσις = que sale, para ...

Dolerite's igneous origins involve the cooling and solidification of magma or lava, giving it a dense and cohesive structure. Dolomite's sedimentary origins, involving the alteration of limestone by magnesium-rich fluids, result in a rock with distinct mineral properties and uses. This difference in formation contributes to their varied ...

Dimensional stones with a black color occupy a prominent place on the international market. Uruguayan dolerite dikes of andesitic and andesitic–basaltic composition are mined for commercial blocks of black dimensional stones. A total of 16 dikes of both compositions were studied and samples collected for geochemical and petrographical analysis. Color …

Dolerite is a medium-grained igneous rock similar in composition to basalt. Unlike basalt however dolerite cooled slowly below the surface forming larger crystals. Dolerite is often found as shallow intrusions such as dykes, sills and volcanic plugs e.g. Slemish, Ballymena. It occasionally has a green tinge due to the presence of the mineral ...
