- [1,2]. Two types of spherules can be distinguished based on their morphology, the presence of high-temperature phases, their geographic distribution, and their stratigraphic position within the KT layer
- [3,4]. Rounded (but also elongated or teardrop-shaped) spherules, some with a preserved glass core reflecting target rock composition
- [5-7], are found only at proximal sites at the base of the KT layer.
