【Ultra-rare insect stalactite mineral replacement process】 The large Millipede with a half-length stalactite, with crystal agate stalactites hidden in amber, is about 100 million years old. A recent study conducted by scholars from many countries found that in the stomachs of some amber insect specimens, there are crystals, agate, stalactites and other silicides, and some insect specimens have pyrite, hematite and other minerals on them. Why is that? "The most likely cause of amber inclusion mineralization is that sedimentary pore water, diagenetic fluids, and groundwater carry mineralizable chemicals into the amber and come into contact with the inclusions," many scholars have deduced. The insect body is a cavity, and the insect body surface and cavities provide opportunities for mineral precipitation and growth. ” This amber was purchased from (Nanjing Institute of Geology and Palaeontology, Chinese Academy of Sciences) Size: 18/12/4mm Weight: 0.4g Inclusions: stalactite mineralized displacement, semi-mineralized and semi-fleshy Dama Lu, which can well observe the whole process of insect metamineralization, and has extremely high research and collection value Scale insects from the Cretaceous Location: Myanmar 21.5/11/3.5mm [Photos] The photos are all taken at macro magnification.
