Libellula depressa, commonly known as the broad-bodied chaser or broad-bodied darter, is a dragonfly in the family Libellulidae. One of the most common dragonflies in Europe and central Asia, its range extends to England, central Asia and the Middle East, with a few limited populations in Scotland. It is not found in Ireland or North Africa, however. This insect is around 39 to 48 millimetres (1.5 to 1.9 inches) in length, with both the male and the female having a broad, flattened abdomen which is brown with yellow patches down the sides. In the male, the abdomen develops a blue pruinescence that covers the brown colour. Both fore and hind wings have a dark patch at the base. This male L. depressa dragonfly was photographed at Wolvercote Lakes in Oxfordshire, England. Photograph credit: Charles J. Sharp

Sphalerite is a sulfide mineral with the chemical formula (Zn,Fe)S. It is found in a variety of deposit types, and is found in association with galena, chalcopyrite, pyrite (and other sulfides), calcite, dolomite, quartz, rhodochrosite, and fluorite. Sphalerite is an important ore of zinc, with around 95 percent of all primary zinc extracted from its ore. Due to its variable trace element content, sphalerite is also an important source of several other metals such as cadmium, gallium, germanium and indium. The zinc in sphalerite is also used to produce brass. This sample was extracted in Creede, Colorado, and features black tetrahedral crystals of sphalerite up to 8 mm (0.31 in) in size, with minor chalcopyrite and calcite, in a 4.5 cm × 3.0 cm × 2.0 cm (1.77 in × 1.18 in × 0.79 in) matrix. This photograph was focus-stacked from 125 separate images. Photograph credit: Ivar Leidus
