Nature Stone Black And White Granite is a volcanic rock, and its main mineral is volcanic rock. Between 50 million and 75.5 million years ago, the lava erupted from the volcano was buried underground. After the high humidity and heat in the volcanic zone, these lava turned into acidic substances, and then the pressure generated by the changes in the crust finally formed the medical stone. From this, it can be inferred that the medical stone is produced in the volcanic area.
After spectral analysis, in addition to trace elements, northern medical stone also contains boron, germanium, copper, zinc, tin, gallium, chromium, nickel, indium, molybdenum, vanadium, cobalt, niobium, tantalum, zirconium, selenium, beryllium, barium , strontium, and rare earth elements lanthanum, cerium, yttrium, ytterbium, etc. Other elements are below the spectral detection limit. The radioactive elements uranium and thorium are above the Clark value. The harmful elements cadmium, lead, mercury and arsenic are also within the spectral detection line.
