What is written on the plate:

Siliceous-Wood

In the coarse-grained river sediments of the Upper Carboniferous of the Kyffhäuser lie mighty tree trunks, which were impregnated with fine-grained quartz (chalcedony). Because of their conifer-like wood structure they are called Dadoxylon. They originate from extinct gymnosperms, the cordaites. For their preservation, silicon-rich weathering solutions were responsible solutions, which permanently impregnate the wood permanently impregnated the wood before decomposition.

Siliceous-Wood is an interesting rock formed from the mineral chalcedony. It is also called "petrified forest" because it mimics the structure of wood.

Siliceous wood is formed by the silicification of wood, in which organic materials are replaced by silica. It is a sedimentary rock formed millions of years ago and is often found in deposits of sand or sediment. Siliceous wood can occur in a variety of colors, including brown, gray, black, or multi-colored. These variations are created by different minerals and impurities during the fossilization process.

The structure of silica wood is fascinating because it retains the outer shape and texture of the original wood. You can see the rings, pores and grain of the wood created by the mineral deposits and growth of chalcedony. The surface of silica wood is often smooth and polished, making the rock a popular material for jewelry and decorative purposes.

Silica wood is known for its metaphysical properties and is often used as a healing stone. It is believed to have a calming and protective energy and can ward off negative energies. It is also considered a symbol of grounding and stability.

The rock pebble is found all over the world, especially in areas with rich sedimentary deposits. There are known deposits in several countries, including the United States, Australia, Indonesia, Madagascar and Brazil.

In terms of uses for silica wood, it has a variety of applications due to its unique aesthetics and durability. It is often made into jewelry such as pendants, bracelets and earrings. Due to its polished surface and beautiful grain, pebble wood is also popular in the creation of art objects, sculptures and decorative items. In addition, it is also used in woodworking to create unique wood finishes.

Overall, silica wood is a fascinating rock with a rich history and multiple uses. Its petrification from wood to mineral chalcedony creates a unique and aesthetically pleasing material that is prized in both jewelry making and the art world.
