What characteristic is not typically associated with globular clusters?

Globular clusters are dense collections of stars that typically contain older star populations and are located in the halo of galaxies. They are characterized by their high density of stars, and their formation predates the significant increase in metallicity seen in later generations of stars.

The reason that higher metallicity is not typically associated with globular clusters relates to the characteristics of their star populations. Globular clusters primarily consist of Population II stars, which are older and formed in the early universe when elements heavier than helium (metals) were less abundant. In contrast, stars that make up the younger, more metal-rich populations (Population I) are found in different environments, such as the disk of galaxies where ongoing star formation occurs. Therefore, it is correct to say that metallicity is generally lower in globular clusters compared to regions where younger stars are found.
