Amber is the resin of Gu Song plants of Pinaceae buried in the stratum, which is buried underground by geological process. After a long period of geological dormancy, the resin lost its volatile components and polymerized and solidified to form yellow-red, transparent to transparent resin fossils. It is a substance similar to organic minerals, and it is named amber because of its yellow-red hue.
Amber is a kind of transparent biological fossil, which is the resin fossil of Pinaceae, Juniperaceae, Taxodiaceae and other plants. Resin dripped down, buried underground for thousands of years, and petrified under the action of pressure and heat. Some of them contain small insects such as bees, which is unusual. Amber is mostly formed by resin fossils of Pinaceae plants, so it is also called "turpentine fossil".
Causes of amber formation
In ancient China, amber was regarded as the soul that turned into stone after the tiger died, and the other was called "the tears of the tiger". These legends all contain the speculation and pursuit of amber by the ancient people in China. People think that amber has the functions of seeking good fortune and avoiding evil, calming the nerves. In the eyes of ancient emperors, amber also had extraordinary significance. Amber is one of the seven treasures of Buddhism. According to records, "the Temple of Heaven uses lapis lazuli, the earthen altar uses amber, the Temple of Heaven uses coral, and the moon altar uses turquoise to decorate the emperor's beads."
Amber is an organic mixture formed by geological processes of coniferous resin from Mesozoic Cretaceous to Cenozoic Tertiary. The formation of amber generally has three stages. In the first stage, resin is secreted from cypress. In the second stage, the resin was deeply buried and petrified, and the composition, structure and characteristics of the resin changed obviously. The third stage is that the petrochemical resin is washed, transported, deposited and diagenetic, thus forming amber.
