Aphanite (Noun)
Meaning
Fine-grained homogeneous rock (such as basalt) containing minerals undetectable by the naked eye.
Classification
Nouns denoting substances.
Examples
- The geologist carefully examined the aphanite sample, noting its uniform texture and composition.
- Aphanite rocks, such as those found in the region, are often difficult to distinguish from one another without laboratory analysis.
- The aphanite formation was characterized by its fine-grained, homogeneous structure, which made it challenging to identify the individual minerals present.
- The basalt aphanite was rich in iron and magnesium, but the exact proportions of these elements could only be determined through chemical analysis.
- The aphanite sample was so fine-grained that even with a hand lens, it was impossible to discern the individual minerals that made up the rock.
