chert (<sedimentary rock by composition>, sedimentary rock, ... Materials (hierarchy name)) |
|
Note: Fine-grained, dense sedimentary rock consisting of interlocking crystals of quartz approximately 30 microns in diameter. Chert and its varieties, such as flint, are non-gem varieties of cryptocrystalline-granular quartz. These stones chip very easily and thus may be fashioned into tools with a sharp edge; they are also used for building.

Additional Notes: |
|
| Dutch ..... Een fijnkorrelig, compact sedimentair gesteente dat bestaat uit in elkaar grijpende kwartskristallen van ongeveer 30 micrometer in diameter. |
| Spanish ..... Roca densa sedimentaria de grano fino formada por cristales de cuarzo ensamblados de aproximadamente 30 micrones de diámetro. El horsteno y sus variedades, como el sílex, son las variedades de no-gema de cuarzo criptocristalino-granular. Esta viruta de piedras puede ser fácilmente formada con instrumentos de borde agudo; estos también son usados para el edificio. |
