Definition of spherulite in English: spherulitenoun ˈsfɛrjʊlʌɪtˈsfer- Geology A small spheroidal mass of crystals (especially of a mineral) grouped radially around a point. Example sentencesExamples - In the absence of salt, the spherulite kinetic assay suggests the presence of spherulites from ~ 40 to 45 min.
- Although they lack the fibrous, radiating crystals that conform to the traditional definition of a spherulite, their cores show a crystal size and density somewhat higher than that of the surrounding rhyolite shell.
- Under the polarized light microscope, addition of a full waveplate to the optical set-up showed that spherulites grown in the absence or presence of salt contain radially oriented amyloid fibrils.
- Initially, no spherulites can be observed when a drop of a spherulite-containing solution is imaged in the microscope.
- These cores will have grown to substantial sizes, giving rise to large spherulites with cores representing a significant proportion of their total volume.
Derivatives adjective sfɛrjʊˈlɪtɪk Geology Their study of whole-rock chemistry has shown somewhat higher silica contents of the spherulitic structures as compared to the host rhyolite glass. Example sentencesExamples - Besides, the aragonitic shell is made up of two oriented layers: an irregular spherulitic prismatic layer and a fine complex crossed lamellar layer.
- These aggregates scatter light, however, due to their amorphous nature, and would not be spherulitic or birefringent.
- The granular to spherulitic microstructure of Carinachites has been documented by several previous authors.
- They typically grow in two-dimensional fanlike and spherulitic arrays.
