Natural stones mainly include granite and marble as large areas for laying floors, floating windows, stepping and wall skirting. Slate products are applied to the background wall and so on, and their original texture has been more and more popular. There are sandstone products such as sound absorption, moisture absorption, no radiation, matte and so on, so that their identities are multiplied into high-grade apartments. Natural stone is characterized by clear texture and natural simplicity, but with color difference. Natural stone is one of the commonly used decorative materials, which is generally expensive. Therefore, when choosing stone materials, room decoration should not only consider economic cost, but also consider the harmony between color and environment.

In the geological field, all rocks are classified into three categories according to their origin: igneous rock, sedimentary rock and metamorphic rock. Igneous igneous rocks, also known as magmatic rocks, are rocks formed by deep magma rising to the surface or near surface. According to the different components, igneous rocks can be divided into four major categories: ultrabasic rocks (represented by peridotite and Kimberley rock), basic rocks (represented by gabbro, diabase, Xuan Wuyan), neutral rocks (represented by diorite, andesite) and acid rocks (represented by granite and rhyolite). According to the causes, the igneous rocks can be divided into deep formed rocks (such as gabbro, diorite, granite, etc.), Asacheng Iwa (such as Kimberley, pyrophyrite, granite porphyry, etc.), and the eruption rocks (such as Xuan Wuyan, andesite, rhyolite, etc.). Igneous rocks occur mainly in batholith, rock plate, dyke, dyke, and rock cover.
