Report Abuse. Olivine is the most common mineral on Earth. Nevertheless it is not the most common on the surface of the Earth. The mineral Olivine makes most of the mantle, which represents about 7/8 (by volume) of the earth. The other 1/8 (by volume) correspond to the core 2. If you consider it as one mineral, feldspar is the most common mineral and quartz comes in second, especially when you consider the whole crust, continental plus oceanic crust. Feldspar is called a group of minerals only for the convenience of geologists. And also consider that the rocks of the seafloor, the oceanic crust, have almost no quartz at all but abundant feldspar. 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 But the most common mineral in the earth as a whole is a high-pressure form of olivine called bridgmanite-formed with a distinct structure and not found at all in the Earth's crust. It's formed below 660km deep in the mantle so is found too deep to be transported back up to the surface in volcanic activity. (Mg,Fe)SiO3.  A pile of minerals. This image shows some of the most common minerals you'll find in rocks. This pile contains plagioclase feldspar, potassium feldspar, quartz, muscovite mica, biotite mica, amphibole, olivine, and calcite. Quartz. Quartz is one of the most common minerals in the Earth's crust. It is made up of silicon dioxide (SiO 2), otherwise known as silica. White sand is primarily made from quartz. Feldspar. Feldspar is the most common mineral on Earth. Since it is most commonly found in granite, this mineral is used mostly as a building material. Feldspar: Characteristics of the two types of feldspar.  1. The most common mineral of the Earth's continents—the world we spend our time in—is quartz, the mineral SiO 2. Nearly all the sand in sandstone, in the deserts of the world and on its riverbeds and beaches is quartz. And also consider that the rocks of the seafloor, the oceanic crust, have almost no quartz at all but abundant feldspar. 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 Mica Minerals. Feldspar is the most common mineral in the Earth s crust, so you are very likely to find it in the rocks you collect! It is found it all of the three rock types, but is most common in intrusive igneous ...more. That means the rocks in your backyard probably have common minerals in them that you can identify. Minerals are divided into different groups based on their chemistry. The most common mineral group on Earth is the silicate minerals, which all have the elements silica and oxygen as their main ingredients. Most silicate minerals form when molten rock cools, either at or near the Earth's surface or deep underground
