The Biblis Patera is a volcano that was extinct millions of years ago in the western area of the Tharsis bulge on Mars , west of Pavonis Mons and southeast of Olympus Mons . It was recorded with the high-resolution stereo camera (HRSC) of the ESA space probe Mars Express on November 8, 2004 with an image resolution of 10.8 meters per pixel. It is about 100 kilometers wide and 170 kilometers long. It rises two to three kilometers above its surroundings. Volcanic mountains of this size are not uncommon on Mars. In the middle of the mountain is a caldera that is 53 kilometers in diameter and about four kilometers deep.
The mountainous rings around the craters are each a relic of lava ejections . In the Biblis Patera it is assumed that the cooled magma layer that forms the crater floor collapsed several times because lava again penetrated the surface. The terraces that have been identified within the caldera testify to these incursions.
