摘要
对自然界90多种元素的单质密度、沸点与熔点温度进行了统计,用元素的这些物理数据,编制了一个"元素物理性质地球化学图"。图中把自然元素分为5个亚类,用温度高低为纵坐标、单质密度大小为横坐标,建立直角坐标系,对每种元素进行了坐标定位,可直观看出自然界中元素以物理性质接近而共生组合,为矿物学、矿床学、地球化学研究提供了纲领性对比图。提出了"元素的液相温度范围"这一概念,凡是液相温度范围大的元素在自然界比较分散,成矿性比较差;凡是液相温度范围小的元素在自然界比较集中,成矿性较好。
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.
