某些物质在紫外光激发下能发出荧光。根据这一特性设计的荧光显微镜,医学部门用来观察细菌及生物切片等;地质工作者用它来鉴定岩石中的孢子花粉;也有的地质人员将岩石制成特定的薄片,在荧光显微镜下研究岩石中分散沥青状态。石油生产部门则把它用来在不粉碎原岩石样品的条件下观察沥青于岩石中的含量及分布状态,判断沥青为原生或次生和石油运移方向等,结合其他地球化学指标评价石油的生、储能力。此外,它还可与偏光显微镜配合,观察岩石矿物中更多的特性。
Some substances fluoresce under ultraviolet light. Fluorescent microscopes designed according to this feature, the medical department to observe bacteria and biopsy, etc .; geologists use it to identify spores in the rock pollen; some geologists will rock made of specific flakes, under the fluorescence microscope Dispersed bitumen in rocks. The oil production department then uses it to observe the content and distribution of bitumen in rock without crushing the original rock sample, to determine whether the bitumen is primary or secondary and the direction of petroleum migration, and to evaluate the petroleum in combination with other geochemical indicators Health, storage capacity. In addition, it can be used with polarizing microscope to observe more features in rock minerals.
