No. Gabbro is a mafic rock (magnesium and iron silicates) while granite is a felsic rock (referring to lighter elements such as potassium in feldspar). Felsic rock contains fewer heavy elements than mafic rocks.
The chemical equivalent to gabbro is basalt, as both are mainly pyroxene and plagioclase feldspar. The difference is that gabbro is intrusive rock and basalt is extrusive.
What else can I help you with?
Is granite the plutonic equivalant of rhyolite?
Yes. Granite and Rhyolite have the same composition.
Do diorite and rhyolite have the same chemical composition?
No, diorite and rhyolite have different chemical compositions. Diorite is a coarse-grained intrusive igneous rock composed mainly of plagioclase feldspar and amphibole, while rhyolite is a fine-grained volcanic rock composed predominantly of quartz, feldspar, and mica.
What do granite and basalt in common?
They are both lithospheric igneous rocks formed by the cooling and solidification of magma/lava and both of them contains silicon.
What rock has the same composition as granite but smaller crystals?
The rock that has the same composition as granite but smaller crystals is called rhyolite. Rhyolite forms from the rapid cooling of molten rock at or near the Earth's surface, which leads to the formation of its fine-grained texture. While both granite and rhyolite are composed primarily of quartz, feldspar, and mica, the slower cooling of granite allows for the development of larger crystals.
What is the same as diorite?
Diorite is similar to granite in that both are coarse-grained igneous rocks composed mainly of feldspar and other minerals like quartz and biotite. However, diorite typically has a higher proportion of plagioclase feldspar compared to granite, which contains more potassium feldspar. Additionally, diorite is often referred to as "the intermediate rock" because it has a composition that falls between basalt and granite. Other rocks that share similarities with diorite include gabbro and tonalite, depending on their mineral content.
Which intrusive and extrusive rocks have the same chemical composition?
Intrusive: Extrusive Equivalent Granite: Rhyolite Diorite: Andesite Gabbro: Basalt
Which igneous rock has the same chemical composition as basalt but a different grain size?
Gabbro has the same chemical composition as basalt (both are mafic rocks) but differs in grain size. Basalt has fine-grained crystals due to rapid cooling at the Earth's surface, while gabbro has coarse-grained crystals as it cools slowly beneath the surface.
Do granite and rhyolite have the same chemical composition?
No, granite and rhyolite have different chemical compositions. Granite is primarily composed of quartz, feldspar, and mica, while rhyolite is a fine-grained volcanic rock with similar minerals but different proportions of each, resulting in distinct compositions.
Is granite the plutonic equivalant of rhyolite?
Yes. Granite and Rhyolite have the same composition.
Are granite and rhyolite similar in a way?
Yes. Rhyolite and granite have the same composition. Rhyolite is the volcanic equivalent of granite.
Two rocks that have the same general chemical and mineral composition?
According to the New York State Earth Science Reference Tables, the two rocks that have the same general chemical and mineral compositions are igneous rocks called andesite and diorite. They both have a composition that consists of quartz, plagioclase feldspar, biotite, pyroxene, and amphibole.
Do diorite and rhyolite have the same chemical composition?
No, diorite and rhyolite have different chemical compositions. Diorite is a coarse-grained intrusive igneous rock composed mainly of plagioclase feldspar and amphibole, while rhyolite is a fine-grained volcanic rock composed predominantly of quartz, feldspar, and mica.
What is the chemical formula for Gabbro?
Gabbro rock is in the same family as Basalt rock and there for has similar chemical composition. Basalt is nearly half composed of silica and has other minerals in much smaller percentages such as titanium dioxide, iron oxide, aluminum and magnesium.
What intrusive igneous rock has the same mineral composition as basalt?
Gabbro is an intrusive igneous rock that has the same mineral composition as basalt. Both rocks are composed primarily of plagioclase feldspar and pyroxene minerals.
Is basalt the fine-grained equivalent of gabbro?
Yes, basalt is the fine-grained equivalent of gabbro. Both rocks are formed from the same magma composition (mafic), but basalt is extrusive, cooling quickly at the Earth's surface, resulting in smaller mineral grains, while gabbro is intrusive, cooling slowly beneath the surface, resulting in larger mineral grains.
What do granite and basalt in common?
They are both lithospheric igneous rocks formed by the cooling and solidification of magma/lava and both of them contains silicon.
Can two igneous rocks be made of the same minerals but have different names?
Yes. The grain texture also matters. For example, basalt and gabbro have the same mineral composition, but basalt, which forms on the surface, has microscopic grains while gabbro, which forms underground, has larger mineral grains.
