Beautiful stones can sing Magical gems can talk There are many stories in nature Magic Stone 12 Mineral Rocks You Must Know in Your Life When geologists identify minerals, they use the same perspective and process as ordinary people to observe things: the first thing that catches the eye is definitely color and shape. The mineral introduced today is very famous, and its "stage name" is jadeite. Jade emerald Anyone who loves gemstones must know jade. The best jade in the world comes from Myanmar, and the jade produced in Myanmar is called Burmese jade. As the name suggests, jade is green. Many minerals in the world may be green, because it is difficult to find minerals in nature that are composed of only one element or a fixed combination of elements. Nature is an open laboratory, and there may always be some impurities or trace elements in naturally formed minerals. Different impurities determine its color. But the natural color of jade is usually green. Geologists call green dark colors, and generally refer to minerals whose natural color is green as dark minerals. Jade is a typical dark mineral, its scientific name is pyroxene. Jadeite rough stone After looking at the color, look at the shape. Pyroxene has two sets of cleavage. The so-called cleavage, to put it simply, is the characteristic that after being hit by a certain force from the outside, it will decompose into small particles of the same appearance. Just like Sun Wukong, by pulling out a handful of monkey hair and blowing it, many small Sun Wukongs appear. It is also like a Russian nesting doll, with one small doll after another hidden inside. The included angle between the two sets of cleavage of pyroxene is 87 degrees, close to 90°. Therefore, when pyroxene is hit by an external force of a certain strength, it will break into small, nearly square particles. Keep in mind that this is an important identification feature of pyroxene. Pyroxene is a large category. Different pyroxenes have different mineral components, slightly different hardness, and a variety of names. It is impossible for many geologists to memorize them all. Jadeite, represented by Burmese jade, belongs to sodium aluminum pyroxene, which is harder than ordinary pyroxene, so it is called "jadeite". This is why Burmese jade is rare and precious. Although jadeite is rare and expensive, pyroxene is a very common silicate mineral. Like olivine, pyroxene is a rock-forming mineral in ferromagnesian rocks, but it is more common than olivine because it occurs not only in ultrabasic rocks but also in basic and intermediate rocks. In simple terms, pyroxene is the kind of person who can be friends with anyone. When we walk in the mountains, if we see green striped rocks with a granular structure, the first thing we have to guess is that this may be diabase. Pyroxene is the main constituent mineral of diabase. Diabase is a rock that comes from the upper mantle and is often found in veins, so it is banded. Diabase contains a lot of information about deep underground and is also closely related to many important mineral resources. Whether you are a geologist or a child who loves nature, knowing about diabase and pyroxene is an important and basic ability. Jade Cabbage We talked about olivine last time, why are we talking about pyroxene today? Because it is the second to crystallize in the process of magma evolution. The most common pyroxene is called augite, which comes from the Greek word auge, meaning bright. This is also an important characteristic of pyroxene. The bright and warm luster lays a good foundation for pyroxene to become an important jade. Remember, the brilliance of pyroxene is the brilliance of glory. Bright but not dazzling, soft but brilliant, are the important characteristics of pyroxene appearance fruit feicuibbs1 fcgc60 |
