矿物、岩石的热发光就是将某些矿物或岩石逐渐加热,当其温度尚未达到赤热(<400℃)之前,矿物或岩石即出现各种颜色的亮光。例如,将螢石、长石或方解石,还有花岗岩、大理岩等的碎屑撒在烧热但未发红的铁板上,在暗室中即可看到闪闪发光的现象。矿物、岩石的这种奇异现象很早就引起人们的注意(E.Newton,1957)。从十七世纪到目前为止,发现绝大部分非金属矿物及极少数的金属矿物都有热发光现象。而一般在加热到150°—250℃之间,少数在更低的温度或更高的温度时,即出现一个,有时两个或更多发光最强的热发光峯。矿物的这种物理
Luminescence of minerals and rocks is the gradual heating of certain minerals or rocks. When the temperature of a mineral or rock has not yet reached red (<400 ° C), various colors of light appear in the mineral or rock. For example, you can see the glittering phenomenon in the dark room by scattering fluorite, feldspar or calcite, and granite, marble and other debris on hot, but not reddish iron. This bizarre phenomenon of minerals and rocks attracted much attention (E. Newton, 1957). From the seventeenth century to the present, it has been found that most non-metallic minerals and very few metallic minerals have luminescence phenomena. In general, however, heating to between 150 ° and 250 ° C, with a few at lower or higher temperatures, produces one, and sometimes two or more, most luminescent peaks of luminescence. This physics of minerals
