The Pleiades volcano consists of a small trachytic stratovolcano, Mount Pleiones, which along with several lava domes and cinder cones with well-preserved craters, rises 500-m above the broad Evans Neve plateau. The Pleiades are located in the Melbourne volcanic province of Antarctica's northern Victoria Land near the western coast of the Ross Sea. Three nested cones containing distinct craters cap Mount Pleiones. A Potassium-Argon age of 3000 years was obtained from the Taygete cone NNE of Mount Pleiones, and the Pleiades appear to be among the youngest volcanic centers in Antarctica. Other dates of 12-40,000 years support a youthful age despite the large analytical uncertainties.

The following references have all been used during the compilation of data for this volcano, it is not a comprehensive bibliography. Discussion of another volcano or eruption (sometimes far from the one that is the subject of the manuscript) may produce a citation that is not at all apparent from the title.
