Cinnabar is the more stable form, and is a structure akin to that of HgO: each Hg center has two short Hg−S bonds (each 2.36 Å), and four longer Hg···S contacts (with 3.10, 3.10, 3.30 and 3.30 Å separations). In addition, HgS is found in a black, non-cinnabar polymorph (metacinnabar) that has the zincblende structure. [5]
The Wakasugiyama Cinnabar Mine (若杉山辰砂採掘遺跡, Wakasugiyama shinshasaikutsu iseki) is an archaeological site with the traces of a late Yayoi to early Kofun period cinnabar production site, located in the Suii neighborhood of the city of Anan, Tokushima on the island of Shikoku in Japan.
Cinnabar moths are about 20 mm (0.79 in) long and have a wingspan of 32–42 mm (1.3–1.7 in). Cinnabar moths are day-flying insects with distinctive pinkish-red and black wings. There is little variation in patterning, although on rare occasions the red markings may be replaced with yellow, or the forewing is entirely red with a black border ...
The St John's Mine is a mineral extraction site approximately three miles north of the city of Vallejo in Solano County, California, United States.The St John's site was used for extraction of cinnabar in the early 1900s. [1]
The dragon blood tree has an upturned, densely packed crown. This evergreen species is named after its dark red resin, which is known as "dragon's blood". Unlike most monocot plants, Dracaena displays secondary growth, D. cinnabari even has growth zones resembling tree rings found in dicot tree species.
Pycnoporus is a genus of fungi in the family Polyporaceae.This genus is distinguished from most other polypores because of its brilliant red-orange color. Modern mycology recognizes five distinct species of Pycnoporus: the type P. cinnabarinus, P. coccineus, P. palibini, P. puniceus, and P. sanguineus.
Obsidian and exotic shells have also been found in Maya tombs. In the Tomb of the Red Queen inside Temple XIII in Palenque, the remains of a noble woman and all the objects inside the sarcophagus were completely covered with bright red vermilion dust, made of ground cinnabar, perhaps intended to suggest blood, the symbol of life.
It is the high temperature form and trimorphous with cinnabar (trigonal structure) and the higher temperature hypercinnabar (hexagonal structure). It occurs with cinnabar in mercury deposits and is associated with native mercury , wurtzite , stibnite , marcasite , realgar , calcite , barite , chalcedony and hydrocarbons .
