Resumo(s)
Zircon is a common accessory mineral in most
rocks and sediments, and although it is ubiquitous, it possesses a considerable petrologic interest. In the scope of CHYNA project, some samples of detrital sediments have been collected in rivers and beaches
from Western Algarve region. The present work
presents the results of the analyses undergone with the intent to document the existing zircons’ variability in these samples. The zircons from 22 samples have
been analysed based on their shape, colour and inclusions. There is predominance of rounded and subrounded grains, generally colourless and without inclusions. Systematic differences between beaches
and rivers are not observed, indicating that both environments have the same zircon sources.
