Pele's tears : ウィキペディア英語版 | Pele's tears
Pele’s tears is a geological term for small pieces of solidified lava drops formed when airborne particles of molten material fuse into tearlike drops of volcanic glass. Pele’s tears are jet black in color and are often found on one end of a strand of Pele's hair. Pele's tears is primarily a scientific term used by volcanologists. Pele's tears, like Pele's hair, is named after Pele the Hawaiian fire goddess of volcanoes. ==Introduction==
Lava fountains produce spectacular displays of volcanic activity with lava spurting out of the vent in a showering cascade of hot molten droplets. Many of the clots aggregate to form the familiar types of lava flows that we see in Hawaiian and Strombolian eruptions.〔Edmonds et al, (2009). Halogen degassing during ascent and eruption of water poor basaltic magma. Chemical Geology 263 (2009) 122-130〕 However, there is also another interesting process that is occurring at the same time that is relatively unknown. This is the formation of glass spherules or droplets of solidified lava known as Pele’s tears. These are black in color and as you can see from the photograph vary in shape and size.
