Pyritteliä

Pyritteliä is a Finnish word that generally translates to "little pyrite" or "pyrite nodule." Pyrite itself is a mineral with the chemical formula FeS2, often referred to as "fool's gold" due to its pale brass-yellow hue and metallic luster. Pyritteliä specifically refers to smaller, often rounded or irregular formations of this mineral. These can occur in various geological settings.

In some contexts, particularly in folklore or historical accounts, pyritteliä might be associated with specific regions or types of soil where pyrite is commonly found. They are not typically of significant economic value as a source of iron or sulfur compared to larger ore deposits. However, their occurrence can be an indicator of certain geological conditions.

The term might also appear in descriptions of fossils or sedimentary rocks where pyrite has crystallized within organic material or sediment pores, forming distinct nodules. These smaller pyrite formations can be of interest to mineral collectors or geologists studying the formation of sedimentary rocks and the diagenetic processes involved. The term emphasizes the diminutive size and distinct, often rounded, morphology of these pyrite occurrences.
