Biblis Patera
Encyclopedia
Biblis Tholus is an extinct Martian
volcano
located at 2.7°N 235.4°E, one of two volcanoes near the center of the Tharsis
volcanism. Along with Ulysses Patera
, it is almost midway between Olympus Mons
and Tharsis Montes
. It is approximately 170 kilometres (105.6 mi) long and 100 kilometres (62.1 mi) wide, rising about 3 kilometres (1.9 mi) from its surroundings.
In the middle of the volcano is a caldera
, named Biblis Patera, possibly formed as the result of collapse of the magma
chamber during eruptions of the volcano. The caldera is 53 kilometres (32.9 mi) in diameter and four kilometers (2.5 miles) in depth.

Tharsis
The Tharsis region on Mars is a vast volcanic plateau centered near the equator in Mars’ western hemisphere. The region is home to the largest volcanoes in the Solar System, including the three enormous shield volcanoes Arsia Mons, Pavonis Mons, and Ascraeus Mons, which are collectively known as...

Ulysses Patera
Ulysses Patera is a Martian volcano. It is located in the Tharsis quadrangle at2.89° north latitude and 121.55° west longitude. It is 58 km across and is named after a classical albedo feature name. Its size changed Sept. 19, 2007 to correspond only to the central depression.Olympusis the...

Tharsis Montes
The Tharsis Montes are three large shield volcanoes in the Tharsis region of the planet Mars. From north to south, the volcanoes are Ascraeus Mons, Pavonis Mons and Arsia Mons. Mons is the Latin word for mountain...

Caldera
A caldera is a cauldron-like volcanic feature usually formed by the collapse of land following a volcanic eruption, such as the one at Yellowstone National Park in the US. They are sometimes confused with volcanic craters...

Magma is a mixture of molten rock, volatiles and solids that is found beneath the surface of the Earth, and is expected to exist on other terrestrial planets. Besides molten rock, magma may also contain suspended crystals and dissolved gas and sometimes also gas bubbles. Magma often collects in...
