Cross section of a barite and silica chimney from East Diamante Caldera in the Mariana volcanic arc. The yellow center surrounds the conduit through which the hot fluids vented; the yellow color is due to a trace of iron in the silica. The chimney also contains moderate amounts of sphalerite and galena. Photo and caption by the United States Geological Survey.

A staff member from the Hawaiian Volcano Observatory sets up a global positioning system in a basalt field on the flank of Kilauea volcano in Hawaii. The goal is to accurately monitor the latitude, longitude, and elevation of a point on the volcano repeatedly through time. These measurements can enable scientists to determine if the volcano is inflating or deflating. This information can be used to anticipate eruptions and better understand the volcano.

Faceted Ametrine: Ametrine has traditionally been faceted in the emerald cut with approximately 1/2 of the stone composed of citrine, 1/2 composed of amethyst, and the dividing line between the color zones perpendicular to the table. This stone has been cut to display the two colors of quartz. It is a 12x8 millimeter emerald-cut ametrine weighing approximately 3.5 carats.

This figure shows idealized cross-sections of smaller simple craters (left, top) and of larger, more complex craters (left, bottom). Simple craters have bowl-shaped depressions with rim diameters of less than about 15 kilometers. Craters with diameters larger than 15 kilometers have more complex forms, including relatively flat, shallow floors, central peaks and slump blocks and terraces on the inner wall of the crater rim.
