Abstract:
This paper compiled a geochemical map of physical properties of elements by using the density of elemental substance, boiling point temperature and melting point temperature of more than 90 kinds of elements in the nature. In the map, the natural elements were divided into 5 subclasses and coordinate positioning of each element were done in the rectangular coordinate system with the ordinate of temperature and abscissa of density of elemental substance. Thus, the readers could easily understand that the close physical properties of elements lead to mineral association by reading the map. This paper proposed the concept of range of liquid-phase temperature of elements. The elements with large range of liquid-phase temperature were dispersed in the nature and the mineralization was poor. On the contrary, the elements with small range of liquid-phase temperature were concentrated and the mineralization was good.
