Droplet-like exogenic fulgurites comprise a minor grouplet of natural glasses resulting from powerful lightning strikes. Reports on such type-V fulgurites are scarce in the literature. In this work, a fulgurite specimen from the thunderstorm that took place on 10th August 2013, in Dallas, TX, USA, has been analyzed using X-ray powder diffraction, X-ray fluorescence, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and infrared and Raman spectroscopy techniques. X-ray diffraction revealed the amorphous nature of the exofulgurite, and X-ray fluorescence showed a high Si, Al and Ca content. Infrared and Raman spectroscopy were key in revealing clear Si–O modes related signatures and a very significant presence of water (OH/H₂O). A parallel with glassy silicate materials, but also with opal-A, was essential in the understanding of the fulgurite’s characteristics. In particular, Raman data evidenced the exofulgurite to have a high degree of depolymerization.

液滴状的外源性辉石包括一小撮天然玻璃，这些天然玻璃是由强大的雷击产生的。在文献中很少有关于这种V型fulgurites的报道。在这项工作中，使用X射线粉末衍射，X射线荧光，扫描电子显微镜，能量色散X射线分析了2013年8月10日在美国得克萨斯州达拉斯发生的雷暴的辉石标本。光谱，红外和拉曼光谱技术。X射线衍射显示出辉石的无定形性质，X射线荧光显示出较高的Si，Al和Ca含量。红外和拉曼光谱法是揭示清晰的Si–O模式相关特征和大量水（OH / H _{2）的关键。}O）。与玻璃状硅酸盐材料以及蛋白石-A的平行性对于理解微晶石的特性至关重要。特别是，拉曼数据证明了辉石具有高度的解聚作用。
