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 leaves are alternately set along the stem, distanced and slightly pointing towards the tip of the branch or overlapping, mostly without, sometimes with a leaf stalk but always without stipules at their base, 1½–14 cm (0.6–5.6 in) long and linear, elliptic, oblanceolate, oval, inverted egg-shaped or spade-shaped, the edge entire or with ...
The hard, green leaves are set alternately along the branches, more or less directed upwards, oval or heart-shaped with an entire margin near the flowers and bluntly oblong and with up to six bony teeth at the tip lower down, 2–8 cm (0.79–3.15 in) long and 2–4½ cm (0.8–1.8 in) wide, softly hairy at first, becoming hairless.
The initially thickly felty or woolly elliptic leaves soon loose these hairs, are 5–8 cm (2−3¼ in) long and ¾–1½ cm (0.3–0.6 in) wide, have a stalk of 1–2 cm (0.4–0.8 in) long at their base, a rounded tip with one, sometimes three bony teeth and horny margins that are sometimes rolled inwards. The alternately set leaves are ...
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.
Its leaves are found only at the end of its youngest branches; its leaves are all shed every three or four years as new leaves simultaneously mature. Branching tends to occur when the growth of the terminal bud is stopped, through either flowering or traumatic events (e.g. herbivory).
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.
