Is it possible for two rocks with the same composition to form different types of rocks give examples?

Is it possible for two rocks with the same composition to form different types of rocks give examples?

1- Limestone and marble are two different rocks, yet both are made predominantly of the mineral calcite. Limestone is a sedimentary rock, whereas marble is metamorphic. These two rock types can be distinguished by their textures….

Type Mafic
Chemistry Basic
Plutonic Gabbro family
Volcanic Basalts

Is it possible for two different types of igneous rocks to have the same composition and same texture explain your answer?

No, if two rocks have the same composition, then they are the intrusive and extrusive equivalents of one another. Thus, they cannot have the same textures. Compare and contrast the two types of sedimentary rocks and give at least two examples of each type.

Why do some igneous rocks contain the same minerals but have different physical characteristics?

Once magma has formed inside the earth, its composition may be modified. Minerals can grow from the magma and separate from it, changing the chemistry of the remaining liquid. Magma can solidify into igneous rock in several different ways, each way resulting in a different igneous texture.

Why can two igneous rocks have the same minerals but different names *?

Why can two igneous rocks have the same minerals but different names? The rocks may be of different sizes. Names of igneous rocks are arbitrary.

Can different types of rocks be made of the same minerals?

Rocks are identified primarily by the minerals they contain and by their texture. Each type of rock has a distinctive set of minerals. A rock may be made of grains of all one mineral type, such as quartzite. Much more commonly, rocks are made of a mixture of different minerals.

How do the types of igneous rocks differ from one another?

Igneous rocks can have many different compositions, depending on the magma they cool from. They can also look different based on their cooling conditions. If lava cools almost instantly, the rocks that form are glassy with no individual crystals, like obsidian. There are many other kinds of extrusive igneous rocks.

What determines the mineral composition of an igneous rock?

In addition to texture, igneous rocks may are classified according to their chemical composition. The most general classification is based on the relative abundance in a rock of felsic (feldspar and silica-quartz) minerals vs mafic (magnesium and ferrum or iron) minerals.

How are rocks and minerals similar and different?

A mineral is a chemical substance made up of one or more chemicals having a definite crystal structure. Rocks do not have a definite chemical composition whereas minerals do. Sometimes a rock may contain organic remains in it. A mineral, on the other hand, will never have any organic material present within it.

Can an igneous rock become an igneous rock?

10. Can an igneous rock become another igneous rock? If so, how? Yes, by melting again and then solidification.

When rocks change does their mineral content also change why?

The new conditions cause the structure of the rock to change and new minerals to grow in place of the original minerals. The rock becomes a metamorphic rock. Like igneous rocks, metamorphic rocks can be raised to Earth’s surface over time. What are the three rock types?
