How are stones formed?

People, with life, can trace their roots to the source.

When we see a beautiful stone, we also want to ask, where did it come from? How did the stone under your feet come out?

Today, we will tell the story of the origin of the beauty stone-the birth of the beauty stone. Enjoy the charm of natural science together.

Stones in nature can be divided into three categories: magmatic rocks, sedimentary rocks and metamorphic rocks. Today, let's look at protolith and magmatic rocks.

The condensed magma forms magmatic rocks.

Magma is the ancestor of magmatic rocks. Magma is a molten mass from the interior of the earth. Magma condenses and consolidates to form magmatic rocks.

There are many types of magmatic rocks, mainly peridotite-picrite (ultrabasic rocks), gabbro-basalt (basic rocks), diorite-andesite (intermediate rocks), granodiorite-dacite, syenite-trachyte, nepheline syenite-xiangyan and vein rocks. It is too complicated. We just need to know that our common granite is magmatic rock.

Look at the inner circle of the earth.

Then, if you think the picture is beautiful, remember that magmatic rocks are formed by the condensation and consolidation of magma, which comes from the deep part of the earth and is hot melt.

What is the microscopic world of magmatic rocks?

Rocks are composed of minerals, and the minerals that make up magmatic rocks mainly include quartz, feldspar, mica, amphibole, pyroxene and so on. In many cases, we need to observe under a microscope.

Let's cut to the chase, Hong.
