In contrast, methane and formic acid are generally considered to be simple examples of organic compounds, although the Inorganic Crystal Structure Database (ICSD), in its definition of "inorganic" carbon compounds, states that such compounds may contain either C-H or C-C bonds, but not both.

Amber occurring in coal seams is also called resinite, and the term ambrite is applied to that found specifically within New Zealand coal seams Earlier Pliny says that a large island of three days' sail from the Scythian coast called Balcia by Xenophon of Lampsacus, author of a fanciful travel book in Greek, is called Basilia by Pytheas.It is assumed that there were well-established trade routes for amber connecting the Baltic with the Mediterranean (known as the "Amber Road").
Pliny states explicitly that the Germans export amber to Pannonia, from where it was traded further abroad by the Veneti.
It is generally understood to be the same as Abalus.
Based on the amber, the island could have been Heligoland, Zealand, the shores of Bay of Gdansk, the Sambia Peninsula or the Curonian Lagoon, which were historically the richest sources of amber in northern Europe.
Opal is another mineraloid because of its non-crystalline nature. ] to be a mineral because of the presence of calcium carbonate crystals within its structure, would be better considered a mineraloid because the crystals are bonded by an organic material, and there is no definite proportion of the components.
Amber is fossilized tree resin, which has been appreciated for its color and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects. Amber is used as an ingredient in perfumes, as a healing agent in folk medicine, and as jewelry.
saria, which by the barbarians was known as Austeravia". In Middle Low German, amber was known as berne-, barn-, b? Molecular polymerization, resulting from high pressures and temperatures produced by overlying sediment, transforms the resin first into copal.
