Mars Volcano, Earth's Dinosaurs Went Extinct About the Same Time
Arsia Mons Volcano on Mars | NASA/JPL
March 20, 2017: New research using observations from NASA's Mars Reconnaissance Orbiter indicates that Arsia Mons, one of the largest volcanoes on Mars, actively produced lava flows until about 50 million years ago. This wide view of the volcano is from the Viking 1 Orbiter.

New NASA research reveals that the giant Martian volcano Arsia Mons produced one new lava flow at its summit every 1 to 3 million years during the final peak of activity. The last volcanic activity there ceased about 50 million years ago—around the time of Earth's Cretaceous-Paleogene extinction, when large numbers of our planet's plant and animal species (including dinosaurs) went extinct.

Located just south of Mars' equator, Arsia Mons is the southernmost member of a trio of broad, gently sloping shield volcanoes collectively known as Tharsis Montes. Arsia Mons was built up over billions of years, though the details of its lifecycle are still being worked out. The most recent volcanic activity is thought to have taken place in the caldera-the bowl-shaped depression at the top—where 29 volcanic vents have been identified. Until now, it's been difficult to make a precise estimate of when this volcanic field was active.

"We estimate that the peak activity for the volcanic field at the summit of Arsia Mons probably occurred approximately 150 million years ago—the late Jurassic period on Earth—and then died out around the same time as Earth's dinosaurs," said Jacob Richardson, a postdoctoral researcher at NASA's Goddard Space Flight Center in Greenbelt, Maryland. "It's possible, though, that the last volcanic vent or two might have been active in the past 50 million years, which is very recent in geological terms."

Richardson is presenting the findings on March 20, 2017, at the Lunar and Planetary Science Conference in The Woodlands, Texas. The study also is published in Earth and Planetary Science Letters.

Measuring about 68 miles (110 kilometers) across, the caldera is deep enough to hold the entire volume of water in Lake Huron, and then some. Examining the volcanic features within the caldera required high-resolution imaging, which the researchers obtained from the Context Camera on NASA's Mars Reconnaissance Orbiter.

The team mapped the boundaries of the lava flows from each of the 29 volcanic vents and determined the stratigraphy, or layering, of the flows. The researchers also performed a technique called crater counting—tallying up the number of craters at least 330 feet (100 meters) in diameter—to estimate the ages of the flows.

Using a new computer model developed by Richardson and his colleagues at the University of South Florida, the two types of information were combined to determine the volcanic equivalent of a batting order for Arsia Mons' 29 vents. The oldest flows date back about 200 million years. The youngest flows probably occurred 10 to 90 million years ago—most likely around 50 million years ago.

The modeling also yielded estimates of the volume flux for each lava flow. At their peak about 150 million years ago, the vents in the Arsia Mons' caldera probably collectively produced about 0.25 to 2 cubic miles (1 to 8 cubic kilometers) of magma every million years, slowly adding to the volcano's size.

"Think of it like a slow, leaky faucet of magma," said Richardson. "Arsia Mons was creating about one volcanic vent every 1 to 3 million years at the peak, compared to one every 10,000 years or so in similar regions on Earth."

A better understanding of when volcanic activity on Mars took place is important because it helps researchers understand the Red Planet's history and interior structure.

"A major goal of the Mars volcanology community is to understand the anatomy and lifecycle of the planet's volcanoes. Mars' volcanoes show evidence for activity over a larger time span than those on Earth, but their histories of magma production might be quite different," said Jacob Bleacher, a planetary geologist at Goddard and a co-author on the study. "This study gives us another clue about how activity at Arsia Mons tailed off and the huge volcano became quiet."

Mars: A Closer Look at Holden Crater | NASA MRO
Holden Crater in southern Margaritifer Terra displays a series of finely layered deposits on its floor (white and light purple in an enhanced color image). The layered deposits are especially well exposed in the southwestern section of the crater where erosion by water flowing through a breach in the crater rim created spectacular outcrops.

In this location, the deposits appear beneath a cap of alluvial fan materials (tan to brown in this image). Within the deposits, individual layers are nearly flat-lying and can be traced for hundreds of meters to kilometers. Information from the CRISM instrument on the Mars Reconnaissance Orbiter suggests that at least some of these beds contain clays.

By contrast, the beds in the overlying alluvial fan are less continuous and dip in varying directions, showing less evidence for clays. Collectively, the characteristics of the finely bedded deposits suggest they may have been deposited into a lake on the crater floor, perhaps fed by runoff related to formation of the overlying fans.

The map is projected here at a scale of 25 centimeters (9.8 inches) per pixel. [The original image scale is 25.9 centimeters (10.2 inches) per pixel (with 1 x 1 binning); objects on the order of 78 centimeters (30.7 inches) across are resolved.] North is up.

NASA Mars Opportunity Rover Panorama: Endeavour Crater Rim
This is a color mosaic made from raw images acquired on March 10, 2017 from NASA's Opportunity rover, now in its 14th year of operation on Mars.

It shows a view from the rim of Endeavour Crater in Meridiani Planum.

The image was made by creating three color images from raw data acquired in red, green, and blue color channels and then sticking the resulting color images together to create a wide angle panorama. Some blurring along the seams is evident, as well as some slight tonal variations where vignetting was reduced. Also the sky has been expanded past the original range of the images. Color is not calibrated but has been adjusted to match approximately what our eyes might see (with some artistic license) based on previous rover images.

The haze is due to fine dust in the air, which can also scatter and absorb light to create blue colorations.

Mars: Layered Deposits in Uzboi Vallis | NASA MRO
Layered deposits in Uzboi Vallis sometimes occur in alcoves along the valley and/or below where tributaries enter it. These deposits may record deposition into a large lake that once filled Uzboi Vallis when it was temporarily dammed at its northern end by the rim Holden Crater and before it was overtopped and breached allowing water to drain back out of the valley.

Layered deposits similar to those here may remain preserved where they were protected from erosion during drainage of the lake. Data from the CRISM instrument onboard MRO shows that clays are within these deposits that may differ from clays found elsewhere on the valley floor. Hence, the clays in these layers may have been washed into the lake from surrounding clay-bearing surfaces.

The map is projected here at a scale of 50 centimeters (19.7 inches) per pixel. [The original image scale is 52.8 centimeters (20.8 inches) per pixel (with 2 x 2 binning); objects on the order of 158 centimeters (62.2 inches) across are resolved.] North is up.
