Amber is a fossil type formed in different geological times. The oldest amber has been seen, found in Northumberland in the UK and Siberia in Russia. These ambers are among the products of the Carboniferous strata about 300 million years ago, nearly 100 million years earlier than the Triassic. The amber containing insect fossils, the oldest found in the Cretaceous strata in Lebanon. In addition, what geological era has Amber crossed?
Resin cultivation into amber has a history
The Cretaceous is an important geological period of amber formation. Amber has been found in this period mainly from amber in China's Xixia, Amber in the Isle of Wight, England, 130 million years old, Lebanese Late Cretaceous amber, Burmese in the Late Cretaceous to Paleogene Paleocene strata in Myanmar. Amber from the Cretaceous period in Romania and so on.
After the Paleogene, angiosperms began to develop, many of which secreted gums, breaking the situation that amber only came from the secretion of resin from gymnosperms. To the Eocene, which is about 50 million years old, some tall, gymnosperms, such as conifers and cedars, distributed between hills and mountains are still important representative trees that secrete a large amount of resin at that time. This situation is also adapted to the Oligocene of 36.5 million years ago. At that time, tall pine and cedar species were widely distributed in the Baltic Sea region. These species, which are capable of secreting a large amount of resin, exist, resulting in a large amount of amber in the sediments of the future.
Neogene is the closest to modern history in the history of the earth, referring to the second generation of the new generation, beginning 23 million years ago, including the Miocene and the Pliocene. Due to the short geological history of the dynasty, the amber produced is not as high as petrochemical. When these ambers are processed into craft ornaments, they tend to change color, and long-term preservation of the surface is prone to cracks. For example, Miocene amber produced in Dominica, amber produced in New Zealand and Malaysia, and so on.
