Basalt
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.
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.
Most of the oceanic crust is made of peridotite. Some basalt and gabbro may also be found.
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.

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.
