金在元素周期表中的位置,复杂的原子核内部构造,以及金的明显的亲铁性,决定了金在地壳中的含量十分稀少(0.004克/吨)。地球科学家们认为,99%以上的金已进入地核之中。近年来,地球物理学、宇宙化学和地球化学研究的进展,地球层圈构造新模型的提出,以及对各类陨石组成的研究,已为近似地计算整个地球及其基本层壳的金的丰度提供了科学的依据。据计算,以铁、镍为主要成分的地核中,金的丰度为2.6克/吨,是地壳金含量的六百多倍。如果在地壳浅部,这个丰度值已经达到了金矿的开采要求。人造地球卫星精确地测量了地球的质量,结果为
The location of gold in the periodic table of elements, the complex internal structure of the nuclei, and the pronounced pro-ferromagnetic properties of gold determine that gold is very scarce (0.004 g / t) in the earth’s crust. Earth scientists believe that more than 99% of gold has entered the core. In recent years, advances in geophysics, cosmic chemistry and geochemistry, the proposition of a new model of the Earth’s ring structure, and the study of various types of meteorites have been carried out to approximate the abundance of gold in the entire Earth and its underlying shell Degree provides a scientific basis. It has been calculated that the abundance of gold in the core containing iron and nickel as the major component is 2.6 g / t gold, which is more than 600 times the gold content in the crust. If the shallow crust, this abundance value has reached the gold mining requirements. Artificial Earth satellites accurately measure the quality of the Earth, the result is
