The technique was evaluated as a means of identifying and quantifying the proportion of dolerite within a bulk sample of granitic road aggregate. The ratio of the absorption depth at 2350 nm to the absorption depth at 2200 nm, for log‐space difference spectra (R2350 : 2200), successfully identified and discriminated with accuracy all ...
These impressive dolerite columns in Tasmania likely formed in the Jurassic period, some 185 million years ago during a massive volcanic event that covered up to a third of Tasmania. The columns are actually a part of a continuous formation over 4,000 km long extending from Australia through Tasmania and into Antarctica.

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 ...

Diabase (), also called dolerite 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). Diabase is the preferred name ...

In Khanozai–Muslim Bagh area, NW Pakistan, the sills are intruded into mainly Triassic–Jurassic successions of Indian platform sediments. They are petrographically identified as dolerite and lamprophyre. The dolerite is a normal dolerite and olivine dolerite and is altered compared with lamprophyre. Lamprophyre is …
The size reduction process of rocks in cone crushers is one of the most important issues, particularly for the secondary and tertiary stages of crushing operations. In this study, 17 different rock types were considered for the evaluation of their size reduction variations that occurred in a laboratory-scale cone crusher. Based on several …

Dolerite is a type of fine-grained, dark-colored igneous rock that is often medium to coarse-grained. It's commonly formed below the Earth's surface from the cooling of molten magma. Dolerite is primarily composed of …
Dolerite or diabase forms when basaltic magma cools moderately fast at shallower depths within the Earth's crust. This magma will intrude into weak zones, faults, or fractures in preexisting rock …
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 visible texture, consisting of euhedral, needle- or rod-shaped plagioclase crystals embedded in a finer matrix of clinopyroxene, typically augite.
The density of rocks varies depending on their composition and porosity. Igneous and metamorphic rocks are generally denser than sedimentary rocks because they contain more iron-rich minerals and have less porosity.
