In planetary geology, tholus is the term for a small domical mountain, usually a volcano. The THEMIS investigation is led by Dr. Philip Christensen at Arizona State University. Ceraunius Tholus and Uranius Tholus are two volcanoes in the Tharsis region of Mars. for details on crediting THEMIS images. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. This image from NASAs Mars Odyssey shows sand dunes within Proctor Crater. … located on a broad dome that is 1,700 by 2,400 kilometers (1,060 by 1,490 miles) in size. Now it is easier to see which areas have been covered and which areas haven't. The caldera indicates several collapses have occured as the magma chamber below has emptied. The Tharsis Montes (Ascraeus, Pavonis, and Arsia) are located on the crest of the crustal bulge and their summits are about the same elevation as the summit of Olympus Mons, the largest of the Tharsis volcanoes. Instrument: Thermal Emission Imaging System. Ceraunius Tholus is on the Tharsis rise, also called the Tharsis bulge. Several The floor of the third highest caldera is. Nighttime infrared (IR) images from THEMIS [1] show previously undescribed wind streaks radial to the summit but centered on the northwest flank. ATABYRIS MONS and such a view will best exhibit the meaning of the several names which they applied to it. 19 … Tharsis Tholus was first mapped as cratered shield material, a unit assigned to all volcanic tholi and paterae in the Tharsis quadrangle ().The same structures were later mapped as volcano of unknown relative age possibly containing a caldera and radial channels (Scott and Tanaka, 1986).Later, Tharsis Tholus was proposed to be a basaltic shield (Hodges and Moore, 1994). They both have effusive eruptions which are relatively quiet and basaltic in nature. Ceraunius Tholus is 130 km across and rises 5.5 km above … This image shows the summit of Hecates Tholus. A linear shift has been applied in the cross-track and down-track direction to approximate spacecraft and planetary motion. At the summit of Jovis Tholus. Mission operations are conducted jointly from Lockheed Martin and from JPL, a division of the California Institute of Technology in Pasadena. Please see the THEMIS Data Citation Note for details on crediting THEMIS images. This image shows the summit of Hecates Tholus. Tholus Summit This image shows the summit of Hecates Tholus. Image information: VIS instrument. Mouginis-Mark et al. The images received on July 4, 1998, however, were very exciting because they included a rare crossing of the summit caldera of a major martian volcano. Uranius Tholus. Evidence is presented supporting the identification of a discrete, well‐preserved air fall deposit generated by explosive volcanism on Mars. Oblique perspective view of the summit region of Hecates Tholus showing the distribution of anomalous heat flow over a 200 Kyr model run (using nominal model parameters). This VIS image shows the western edge of the summit caldera of Ceranus Tholus, one of the smaller volcanic constructs of the Tharsis region. The plateau is five to four seven kilometers above the zero altitude of Mars. Tholi on Mars are central vent volcanoes with well-defined summit calderas (BVSP 1981) of up to 10 km in diameter and basal dimensions between 50 and 200 km and a height of 4–10 km (Plescia 2004).They have relatively steep peripheral flanks. Pavonis Mons. 4e) are interpreted to be formed by melting of summit snowpack, and lateral runoff and incision. The Latin word 'tholus' means a conical dome and the base of Ceraunius Tholus is 80miles across, while the peak rises 3.4miles above the surrounding plains. NASA's Jet Propulsion Laboratory manages the 2001 Mars Odyssey mission for NASA's Office of Space Science, Washington, D.C. The deposit is located immediately to the west of the summit caldera of Hecates Tholus (32°N, 209°W), the northernmost of the three volcanic constructs in the Elysium Planitia region. Tholus Summit. Adjust the transparency slider (Fill Alpha) to the middle of the slide bar. Our image only shows a portion of the summit. Feature of the month – september 2012 ALPO. It exhibits a spur and gully morphology never described in the summit area of volcanoes of this type on Mars, but sometime observed on exceptionally high canyon walls of Valles Marineris [7]. In our nominal case, the peak surface heat flow anomaly in the summit region is. Elysium Planitia is the second largest volcanic region on Mars. It is 270 miles in diameter, almost 12 miles high, and the summit caldera is 72 miles wide: NASA/JPL/ASU Scientists discovered significant amounts of a silica mineral in a rock sample at Gale Crater on Mars called tridymite. This image from NASAs Mars Odyssey shows the western edge of Ariadnes Colles. This image shows the summit of Hecates Tholus. We note that this part of the caldera rim of Tharsis Tholus is also exceptionally high (up to 5 km), because it merges with a landslide rim. Latitude 31.6°N, Longitude 150.0°E. Note: this THEMIS visual image has not been radiometrically nor geometrically calibrated for this preliminary release. Fully calibrated and geometrically projected images will be released through the Planetary Data System in accordance with Project policies at a later time. 3), radial valleys (Fig. Both have summit pits or calderas and long lava flows or channels.
