This is neither an impact crater nor a volcano. It is a perfect circular
intrusion, about 10 km in diameter with a topographic ridge up to 600 m
high. The Kondyor Massif is located in Eastern Siberia, Russia, north of
the city of Khabarovsk. It is a rare form of igneous intrusion called
alkaline-ultrabasic massif and it is full of rare minerals. The river
flowing out of it forms placer mineral deposits. Last year 4 tons of
platinum were mined there. A remarkable and very unusual mineralogical
feature of the deposit is the presence of coarse crystals of Pt-Fe alloy,
coated with gold. This 3-D perspective view was created by draping a
simulated natural color ASTER composite over an ASTER-derived digital
elevation model.
The image was acquired on June 10, 2006, and is located at 57.6 degrees
north latitude, 134.6 degrees east longitude.
