The volcanic rock pumice, often used in skin careįor the removal of callouses, contains vesicles which is one of the reasons it is When gas escapes from cooling molten material, it creates small pinprick holes orĬavities in a rock's surface. They do not contain the common earth mineral quartz, and in general do not contain Meteorites tend to look different from the ordinary terrestrial rocks around them.

Actual size of area pictured is approximately 10 cm across. Flow lines may be found on the surface of irons, stones, and stony-irons but, like fusion crust, they are fragile and may disappear over time, due to the processes of terrestrial erosion. Iron meteorite with flow lines: This close-up image of the main mass of the Bruno iron meteorite (found near Bruno, Saskatchewan, 1931) shows a delicate and intricate pattern of flow lines, created as the surface of the meteorite literally melted and flowed. Such as runoff (slag) from old smelters, and castoff iron implements that Such as basalt, and many different types of man-made metallic by-products Hematite (many of which will stick to a magnet), dark black rocks Our planet is rich in terrestrial iron oxides such as magnetite and Meteorite, but turns out instead to be a common earth rock isĪffectionately and humorously dubbed a meteor-wrong. Fusion crust is thin and fragile and will weather away over time, so a recently fallen stone will exhibit a dark black crust with no weathering or rust stains. Note the very fresh, rich black fusion crust which is reminiscent of a charcoal briquette.

This specimen was picked up immediately after the fall. It is an ordinary chondrite (H5) and an excellent example of a complete fusion crusted stone. Stone meteorite with fusion crust: This 307.1-gram stone meteorite fell as part of a shower on Octoin Mauretania. Than one percent turn out to be genuine visitors from outer space.
