👉 Microspherulitic is a type of mineral that consists primarily of tiny, spherical particles. These particles are typically less than 1-2 microns in diameter and can be found in various minerals such as quartz, calcite, and feldspar. They are often referred to as "microspherules" or "micrystallites." Microspherulitic minerals have a unique crystal structure that allows for their distinct appearance and properties.
