mineral olivine in crystal form

Mineral olivine

Olivine is a mineral that contains a lot of magnesium and iron. When a rock contains high amounts of magnesium and iron, it may be called an olivine stone.

100% olivine is called peridot, this is a gemstone used in jewelry. This type of "olivine" is not suitable for construction applications.

Chemical composition olivine

Olivine belongs to the group of neososilicates and can be recognized by the chemical formula (Mg,Fe)2SiO4. Mg stands for magnesium and Fe stands for iron .

When minerals are rich in magnesium or iron, they are called forsterite (Mg2SiO4) or fayalite (Fe(II)2SiO4). The ratio of silica to oxygen is the lowest possible with neosilicates, namely 1 to 4.

Where do you find olivine?

Olivine is often found in dark-colored rocks on the Earth's surface. It originates from rocks and mountains that are usually located on the boundaries of tectonic and divergent plates. This is a huge advantage. The extraction of olivine stone is therefore a lot easier and more sustainable. There is no need to drill or dig deep into the ground to mine the olivine rock.

Olivine has a high crystallization temperature and is one of the first minerals to crystallize from the heat of the earth. Olivine is rarely found in sedimentary rocks because it is easily altered by weathering.

Olivine can be found in sediments or sand if scattered near a source. Olivine crystals also form from the metamorphosis of dolomite or dolomite limestone.

Olivine is present on every continent and therefore has a suitable solution for every country. Here you will find an overview of where olivine can be found. It is a complete page about the origin of Olivine .

Olivine stone

Olivine stone is gray-green in color and may only be called olivine stone if it contains high concentrations of the mineral olivine. A good example of what the rock looks like is the gradation 16/32 mm . This is the largest gradation of olivine stone that greenSand has and here the color and structure are clearly visible.

In theory, there is no such thing as an olivine stone. But for convenience it is called that. Stones contain several minerals and organic substances.

What you will also often encounter is the term olivine sand and olivine split. Then remember that this is a rock with a high concentration of the mineral olivine. The reason olivine is so well known today is because it naturally clears CO2 .

Olivine CO2

Olivine cleans up CO 2 through weathering. The earth and people release CO2 , which then ends up in the air. It is absorbed by clouds and returns to earth through rain. You can read more about the impact of olivine on this page.

Olivine weathering

Weathering is a process that occurs when a rock is in contact with water. It can be compared to the rusting of iron. During this process a chemical reaction occurs in which the CO 2 is converted into lime. You can find the exact operation here .

Olivine effect

Olivine cleans up CO 2 and at the same time feeds the soil. As described above, the CO 2 is cleaned up by weathering with rainwater.

During weathering, the CO 2 is converted into lime (magnesium, silicate and manganese). These are important nutritional elements for plants. It has been chemically proven that magnesium, in its natural form, can replace lime, resulting in stronger and healthier plants.

This olivine effect makes olivine healthier for air and soil. A side effect is that the olivine effect deacidifies the soil. This is a very beneficial effect for the nitrogen crisis. You can see a nice and clear video about the olivine effect here .

Olivine impact climate change

Now that you know that olivine clears CO2 . Are you also curious about the impact on the climate?

cleaning up CO2

There are three ways to remove CO 2 from the air: plants do this through photosynthesis, the oceans dissolve it, but rocks also remove carbon from the air through weathering. More CO 2 is stored through weathering in lime mines than in seawater, atmosphere and biosphere combined. Olivine is the biggest player when it comes to CO2 weathering. This is because olivine contains high concentrations of magnesium. Here you can read everything about the effect of olivine.

CO2 cycle

CO 2 is released and is stored in the ocean, in wood and lime, this is called the CO 2 cycle. For millions of years the earth has kept the amount of CO 2 in the air in balance. The weathering of rocks has played a major and important role in this.

Olivine stone can be used in a variety of construction applications. By using olivine stone as an alternative to cycle paths, hiking trails, etc., we can jointly ensure that the CO 2 cycle is back in balance.

Below you can read more about all applications to combat climate change.

The great CO2 cleanup

Olivine is a natural product that works on land and in sea water. Olivine stone can be used on land by using it as an application in construction or by spreading it as a powder for improving soils. greenSand is a company dedicated to providing more applications and more possibilities, so that together we can spread more olivine around the world. With the ultimate goal of restoring the CO 2 cycle.

Olivine applications

Olivine as a rock can be used in various ways in construction and agriculture. By spreading olivine in as many places as possible, we give the earth more surface area and capacity to clean up CO2 . Below we have collected the most important olivine applications for you.

Olivine semi-hardening

A sustainable semi-paving of olivine is good for the air and the soil. A semi-paving is often already necessary, so why not opt ​​for a sustainable semi-paving of olivine? By using olivine stone as semi-hardening, the CO 2 clearing process can be accelerated and we can generate more surface area, which positively contributes to the CO 2 cycle.

Another big advantage of olivine semi-paving is the water permeability. By opting for a water-permeable semi-paving, more rainwater seeps into the ground and less water flows directly to the sewer system, which reduces the risk of puddles.

Olivine viewing path

Olivine schouwpad, a sustainable schouwpad for next to the Dutch railways. Our country has almost 7,000 km of railways. With a viewing path of 1.5 meters wide and 5 cm thick, you can already clear 168 tons of CO 2 per km of viewing path. This means that we can clear up 1176,000 tons of CO 2 with all the railways in the Netherlands. And those are just the railways in the Netherlands. Just look at the Hoekse Lijn project , where 16,000 tons of CO 2 are currently being cleaned up. Did you know that this project was not realized from the climate perspective, but because the olivine stone is low maintenance? Just watch the video on the page.

Olivine soil conditioner

Olivine contains a lot of magnesium that the plants love. This makes it an ideal means to ensure a healthy soil. Olivine also improves drainage and soil porosity, reducing the amount of water needed to water the plants. In addition, it helps to sequester carbon in the soil. It has been proven by the University of Wageningen that olivine promotes plant growth by 15.6%. Also spoil your plants with our olivine soil improver .

Olivine lime substitute

Olivine is one of the most sustainable lime substitutes in the Netherlands. This is because 1 kg of olivine is equivalent to 1.43 kg of lime. It naturally raises the pH value and, of course, also clears up CO 2 . Also deacidify your soil naturally with the olivine lime substitute .
