Get PriceDiabase is actually a variety of gabbro which consists mainly of labradorite feldspar augite magnetite and olivine The grain size of diabase is on the smaller side Diabase and gabbro have the same general mineral composition as basalt but they have a larger grain size Basalt is identical to diabase and gabbro but is very fine grained
Get PriceGabbro is generally coarse grained with crystals in the size range of 1 mm or greater What type of rock is basalt Basalt is a hard black volcanic rock Basalt is the most common rock type in the Earth s crust Depending on how it is erupted basalt can be hard and massive Figure 1 or crumbly and full of bubbles Figure 2
Get PriceMafic Composition Gabbro Vesicular Basalt Gabbro is a coarse grained mafic igneous rock made with mainly mafic minerals like pyroxene and only minor plagioclase Because mafic lava is more mobile it is less common than basalt Gabbro is a major component of the lower oceanic crust Basalt is a fine grained mafic igneous rock
