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.
The cinnabar moth (Tyria jacobaeae) is a brightly coloured arctiid moth found as a native species in Europe and western and central Asia then east across the Palearctic to Siberia to China. It has been introduced into New Zealand , Australia and North America to control ragwort , on which its larvae feed.
The first documented use of vermilion pigment, made with ground cinnabar, dates to 8000–7000 BC, and was found at the neolithic village of Çatalhöyük, in modern-day Turkey. Cinnabar was mined in Spain beginning in about 5300 BC.
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]
Becker concluded the sulfur of Sulphur Bank was deposited after the cinnabar had been deposited, because he could find no evidence of acid farther than 20 feet (6.1 m) below the surface of the mine. He wrote the acid would have thrown the cinnabar down, instead of migrating up with the sulfur through the basalt rock which covered the mine site ...
The levels of lead found in the six cinnamon products were elevated from what regulators expect, but lower than those that have been found in other products. Lead was found at concentrations ...
Widely distributed in Eastern Northern America, it can be found from June to October, mostly on the ground in broadleaf and mixed broadleaf/conifer forests. It usually occurs scattered or in small groups. [5] It forms mycorrhizal associations with forest trees and shows preference for acidic soils. [6]
