bredfältfluorescens

Bredfältfluorescens, also known as field fluorescence, is a phenomenon observed in certain types of rocks and minerals under ultraviolet (UV) light. The term is derived from Swedish, where "bredfält" translates to "wide field," and "fluorescens" refers to fluorescence. This effect is characterized by the emission of visible light by the rock or mineral when exposed to UV radiation. The fluorescence is typically observed as a glow or coloration that can vary in intensity and hue depending on the specific mineral or rock composition.

The mechanism behind bredfältfluorescens involves the absorption of UV light by certain minerals, which then re-emit this energy as visible light. Common minerals known for their fluorescence include calcite, fluorite, and certain types of quartz. The fluorescence can be induced by natural sources of UV light, such as sunlight, or by artificial sources like UV lamps used in geological and mineralogical studies.

Bredfältfluorescens is significant in geological and mineralogical research as it provides valuable information about the composition and history of rocks and minerals. It is also utilized in the identification and classification of minerals, as well as in the study of geological processes. The phenomenon is also appreciated by collectors and enthusiasts for its aesthetic qualities, as the fluorescent glow can create visually striking displays under UV light.

In summary, bredfältfluorescens is a fascinating optical property exhibited by certain rocks and minerals, characterized by their ability to emit visible light when exposed to ultraviolet radiation. This phenomenon has both scientific and aesthetic significance, contributing to our understanding of geological materials and their properties.
