What mineral makes up 90 percent of the earth's crust? Making the world better, one answer at a time. There are ten minerals that are so common that they make up 90% of the Earth's crust. These are quartz, orthoclase, plagioclase, muscovite, biotite, calcite, dolomite, halite, gypsum, and ferromagnesian minerals.

What is the earth's crust made of? Earth's crust is made up of several elements: oxygen, 47 percent; silicon, 27 percent; aluminum, 8 percent; iron, 5 percent; calcium, 4 percent; magnesium, potassium and sodium, 2 percent. The crust is divided into huge plates that float on the mantle, the next layer.

Composition of the crust Chemical elements in the crust. The most common chemical elements in the crust are oxygen (46.6%), silicon (27.7), aluminum (8.1), iron (5.0), calcium (3.6), potassium (2.8), sodium (2.6), and magnesium (2.1). These figures vary among different studies because we really have no way to know for sure.

What Are The Most Common Minerals On Earth? Rocks and minerals are not even evenly distributed on the surface. Igneous rocks make up approximately 95% of the upper 10 miles of earth’s crust. Rocks with light minerals, like granite, make up most of the continents. Rocks with dark minerals, like gabbro and its volcanic variety basalt, make up the oceanic crust, covering two thirds of earth. Every year along the mid-ocean ridges 0.5-0.7 cubic miles of new igneous rocks form.

The Composition of the Earth's Crust Elemental Composition of the Earth's Crust There are eight elements that comprise most of the Earth's crust. The first is oxygen (0), which comprises 47 percent of the crust and is usually associated with silicon, which is the next largest element in the crust's composition. Silicon (Si) comprises 28 percent of the Earth's crust where it works with oxygen to form silica.

- Measured by mass, silicon makes up 27.7% of the Earth's crust and is the second most abundant element in the crust, with only oxygen having a greater abundance. Silicon is usually found in the form of complex silicate minerals, and less often as silicon dioxide (silica, a major component of common sand).t is most widely distributed in dusts, sands, planetoids, and planets as various forms of silicon dioxide (silica) or silicates. Over 90% of the Earth's crust is composed of silicate minerals, making silicon the second most abundant element in the Earth's crust (about 28% by mass) after oxygen.

Earths Crust Ten silicate minerals. Ten minerals that make up 90% of the crust are all silicates because all contain silicon and oxygen. Quartz is pure silicon and oxygen. The rest of the silicate minerals include additional elements in the minerals structure.he Earths crust is the outermost layer of our planet and is less than 1% of the Earth's volume. The crust and the mantle contain different kinds of rocks making them chemically different. The upper mantle rocks are primarily peridotite.

- So in the Earth's crust, feldspar in the most common mineral. BUT, 3. The Earth consists of a very thin rocky crust on top of a very thick rocky mantle. Compared to the mantle, the crust is small enough to ignore. And the most common mineral in the mantle is olivine, or at least the compound (Mg,Fe) 2 SiO 4.

crust Earth’s crust is divided into two types: oceanic crust and continental crust. The transition zone between these two types of crust is sometimes called the Conrad discontinuity. Silicates (mostly compounds made of silicon and oxygen) are the most abundant rocks and minerals in both oceanic and continental crust. Oceanic Crust. Oceanic crust, extending 5-10 kilometers (3-6 kilometers) beneath the ocean floor, is mostly composed of different types of basalts.

- As we discussed in a previous lecture, the relative abundance of elements in the Earth's crust determines what minerals will form and what minerals will be common. Because Oxygen and Silicon are the most abundant elements, the silicate minerals are the most common.s we discussed in a previous lecture, the relative abundance of elements in the Earth's crust determines what minerals will form and what minerals will be common.

Composition of the crust Feldspars are very common minerals in the crust, more than half (51%) of the crust is made up of this mineral group. Mica and clay minerals are also common, both comprise about 5% of the crust. Hence, aluminum is extremely widespread as well.asalt is very common rock type, especially in the upper part of the oceanic crust. Andesite is somewhere in the middle. It is pretty common rock type associated with subduction zone volcanism but not as widespread as basalt. By the way, the average composition of the continental crust is that of andesite.

Earth The center of the earth (the Earth's core) is mostly iron (88.8%), nickel (5.8%), sulfur (4.5%), and less than 1% other things. The Earth's crust is largely oxygen (47%). Oxygen is normally a gas but it can join with other chemicals to make compounds like water and rocks. 99.22% of rocks have oxygen in them.
