What is the dark colored rock the makes up most of the oceanic crust?
Basalt
Does basalt contain calcium carbonate?
No, basalt does not contain calcium carbonate. Basalt is a volcanic rock primarily composed of silicate minerals, such as plagioclase and pyroxene, and it typically has a low concentration of carbonates. Calcium carbonate, on the other hand, is commonly found in sedimentary rocks like limestone and is not a significant component of basalt.
Does basalt contain minerals?
Yes, basalt contains several minerals, primarily plagioclase feldspar, pyroxene, and olivine. These minerals form during the cooling and solidification of lava, which is the defining characteristic of basalt as an igneous rock. Additionally, basalt may contain smaller amounts of other minerals such as magnetite and ilmenite, contributing to its overall composition.
What is the rock that makes up most of oceanic crust?
Most of the oceanic crust is made of peridotite. Some basalt and gabbro may also be found.
Does basalt contain fossils?
Basalt is an igneous rock that forms from the cooling of lava, and it typically does not contain fossils. Fossils are more commonly found in sedimentary rocks where the remains of organisms are preserved in layers of sediment over time.

What is two extrusive ignious rocks that contain crystals?
Rhyolite and basalt
What makes up oceanic plates?
mostly basalt
What makes good floor tiles?
basalt, marble

A rock that makes up much of the ocean floor?
basalt
What type of rock makes up most of Iceland?
basalt
What makes basalt not a minerals?
Basalt consists of multiple minerals. Pyroxene, calcium-rich plagioclase, and sometimes olivine are key minerals in basalt. Basalt that cools rapidly may form glass, which contains no minerals because it lacks a crystal structure.
Does basalt contain fossils?
Basalt is an igneous rock that forms from the cooling of lava, and it typically does not contain fossils. Fossils are more commonly found in sedimentary rocks where the remains of organisms are preserved in layers of sediment over time.
What makes the eclogite rock?
Extreme metamorphism of oceanic crustal basalt.
