Nat Geo: Rare fossil supervolcano discovery in Italian Alps captures attention

Basalt%20Yellowstone.jpg SMU geologist James E. Quick led a team of geologists that discovered a rare fossil supervolcano in the Sesia Valley of the Italian Alps.

Now news journalists from internet, radio, television and newspaper outlets are interviewing Quick and his team, which was back at the site this September for further research. The team made the discovery two years ago and announced it in July. The discovery will advance scientific understanding of active supervolcanoes, like Yellowstone, which is the second-largest supervolcano in the world and which last erupted 630,000 years ago.

Sesia Valley’s unprecedented exposure of magmatic plumbing provides a model for interpreting geophysical profiles and magmatic processes beneath active calderas. The exposure also serves as direct confirmation of the cause-and-effect link between molten rock moving through the Earth’s crust and explosive volcanism.

James%20Quick.jpg Quick is a professor in the SMU Roy M. Huffington Department of Earth Sciences as well as SMU associate vice president for research and dean of graduate studies.

Co-authors of the report are Silvano Sinigoi, Gabriella Peressini and Gabriella Demarchi, all of the Universita di Trieste; John L. Wooden, Stanford University; and Andrea Sbisa, Universita di Trieste.

Excerpt from the Oct. 1, 2009 National Geographic News article “‘Supervolcano’ with twisted innards found in Italy”:

By Ker Than

Long before Vesuvius blew its top and smothered Pompeii, Italy was rocked by a “supervolcano” eruption so powerful it possibly blocked out the sun and triggered prolonged global cooling, scientists say.

The now fossilized supervolcano last erupted about 280 million years ago, leaving behind an 8-mile-wide (13-kilometer-wide) caldera, which was recently discovered in the Italian Alps’ Sesia Valley.

What’s more, seismic forces have twisted the volcano’s interior, giving scientists an unprecedented glimpse deep into the feature’s explosive plumbing — and a better shot at deciphering when the next one might blow.

The fossilized remains of a supervolcano that erupted some 280 million years ago in the Italian Alps are giving geologists a first-time glimpse at the deep “plumbing system” that brings molten rock from far underground to the Earth’s surface.

James E. Quick of Southern Methodist University in Texas and his team discovered the “fossil,” or extinct, supervolcano in the Alps’ Sesia Valley two years ago, but they are just now reporting the results after careful study.

The researchers estimate the ancient eruption sent about 1,102 cubic kilometers of volcanic ash into the atmosphere. For comparison, the supervolcano under Yellowstone National Park, which erupted 630,000 years ago, produced about 2,204 cubic kilometers.

New Mexico “Childhood Archaeology Project” unearths centuries of change

SingleMarblesSMall.jpg Sunday-Eiselt%2Cgs.jpg Old restored homes — gentrified with galleries, shops and restaurants — ring the historic and picturesque plaza of Ranchos de Taos in northern New Mexico.

The plaza, once a hub of village life in Ranchos de Taos, these days is notably absent of children. Their families have been driven to the outskirts of the Catholic village by a booming tourism industry that has pushed up property values.

But the children left their mark, says archaeologist Sunday Eiselt, who for three years has led digging crews in some of the homes through her work at the Archaeology Field School of the SMU-in-Taos campus of Southern Methodist University. They’ve unearthed children’s artifacts up to 100 years old, including pieces of clay toys, tea sets, doll parts, clothing, mechanical trains, jacks, marbles, child-care implements, modern plastic Legos, Barbie doll parts, action figures and jewelry.

Eiselt’s interest in childhood artifacts is unique because children are rarely documented in archaeological narratives — particularly in the Spanish borderlands, where they appear as victims of slavery and boarding schools.

Her pilot excavations in 2007 and 2008 revealed patterns that suggest children were integral to the workforce and household economy in the 18th and 19th centuries. In the 1930s, the evidence shows, they were drawn from the workforce into the home and pulled as a consumer into the expanding commercial market as well as into the public education realm, says Eiselt, an SMU anthropology professor.

Copy%20of%20ClayHOrseSmall.jpgNow Eiselt is launching the SMU-in-Taos Childhood Archaeology Project — thanks in large part to community relationships and trust formed over the past few years. A systematic and scientific examination of children’s lives will provide new perspectives on the dynamics of Spanish and American occupation of New Mexico, she says.

“When state resources and institutions are aimed at children’s lives, cultures are irrevocably changed,” she says. “We’re asking, ‘What can the archaeology of children tell us about the transformation of Hispanic Rio Grande communities over time?'” We’re investigating the impact of state expansion on child-rearing and education in the Spanish borderlands by examining childhood on the Ranchos de Taos Plaza.”

SMU-Picture.gifThe Ranchos de Taos artifacts bear witness to changes the community has undergone over the past 200 years, she says. Settled by the Spanish in 1716, Ranchos de Taos ultimately absorbed many aspects of Anglo culture. The Catholic grade schools eventually closed, and Hispanic children were forced into the public school system.

“What we’ve learned so far is that as you go back in time children are harder to see because you don’t have the inundation of commercial toys,” Eiselt says. “During the Depression Era the plaza is fairly active. We see a lot of communal games like jacks that kids play together. Later in the ’60s and ’70s we see more toys that are individually based and that promote individual play.”

Now Eiselt has the blessing of Ranchos de Taos adults who are interested in their history and anxious to preserve their heritage. The plan is to include children in grades K-12 in the project with fully integrated activities such as oral history interviews, photographs, history education and hands-on excavating. Besides archaeological survey and excavation, Eiselt is digging through files at the state historical archives in Santa Fe. There she’s gathering clues about everything from riddles and toys to customs and education.

The Childhood Archaeology Project also will include analysis of images made by Works Progress Administration photographer John Collier Jr., who chronicled the Great Depression. Many of his photos are on exhibit at the University of New Mexico’s Maxwell Museum of Anthropology.

taos-santuario-de-chimayo-200.jpgWhile excavation and research progresses, service projects in the local community also will continue as they have the past few years. University students at the field school work closely with property owners. Each summer 30 undergraduates engage in three weeks of hard labor to re-plaster the historic San Francisco de Asis, a church that’s not only venerated locally by its parishioners but also appreciated worldwide as a unique architectural monument.

“It shows our commitment to the community. The people understand we’re not here to exploit the children. Your hands really become part of this church,” Eiselt says. “More and more archaeologists are having to work in communities — not just in remote places. So we’re working with the descendants of the people we’re studying. It’s much more dynamic. The secret to this kind of archaeology is you don’t try to control it. You have to step back and let it unfold.”

Some of the village’s historical traditions include the deeply religious folk society of men called Los Hermanos Penitentes. Pervasive in New Mexico in the 1800s, members of the society carried crosses and flagellated themselves to atone for their sins. Public until almost the turn of the 19th century, the society was forced underground when Catholic clergy increasingly frowned on their practices.

“The student archaeologists have earned the trust of this lay brotherhood sufficiently to be invited to excavate a morada. These are the chapels where many of their rituals take place and so this is a great honor for us,” says Eiselt. Work begins next year in tandem with the Childhood Project. — Margaret Allen

Precedent for America’s move toward restitution for human rights abuses

A growing global movement to apologize and make restitution to victims of human rights abuses is now gathering steam in the United States, but it won’t be a first for the country, says the president of The Western History Association.

“In reviewing the history of reconciliation in the American West, I’ve found three examples of government restitution — where we acknowledge we’ve participated in human rights abuses and offered either an apology, restitution, reparation or all three,” says Sherry Smith, associate director of the Clements Center for Southwest Studies at SMU and an SMU history professor.

The state of Montana granted posthumous pardons to Germans and Austrians convicted and imprisoned under repressive sedition laws during World War I; the U.S. government paid reparations to the heirs of Japanese Americans relocated to incarceration camps during World War II; and in a landmark native-lands case, Arizona returned 6,000 acres to the Hualapai tribe in the 1940s and the U.S. government set up the Indian Claims Commission.

“These are tiny steps considering the magnitude of the problem. But they helped turn the corner of deep injustice,” Smith says. “It’s never too late to do the right thing.”

The global move toward reparations and restitution has largely evolved since World War II, beginning with Germany after the Holocaust, Smith says. Since then other nations and some private corporations have apologized or offered reparations to reconcile the past.

Increasingly, governments are responding to victims’ rights groups that are demanding reconciliation and restitution for slavery, war crimes and other institutionalized abuse.

Most recently, the U.S. Senate in June passed a resolution apologizing for slavery — although it didn’t offer any monetary reparation.

“The United States is in the beginning stages of this movement,” says Smith, noting that historians have been a critical part of the process as they collect victims’ testimony and verify abuses through documentation.

“To the extent reconciliation includes chronicling and teaching the sometimes troubled past, historians are central to that,” says Smith.

While Smith isn’t drawing moral or ethical conclusions, she did say “the work that historians do can have social justice implications. We need to tell the stories of abuse and keep retelling them as part of the reconciliation process. But victims also need more than words. They want acts, too.”

Smith will address “Reconciliation and Restitution in the American West” at the Western History Association’s annual conference in October in Denver. More than 900 association members from museums, universities and government agencies attend the conference. — Margaret Allen

Angola: Final fossil frontier, museum in the ground

Angola%20006a.jpg Fossils in the rock outcrops of the coast of Angola in Africa are a “museum in the ground,” says SMU vertebrate paleontologist Louis L. Jacobs. Louise Redvers with Agence France Presse interviewed Jacobs. BBC and others published the story “Angola: Final frontier for fossils.”

“Angola is the final frontier for palaeontology,” Jacobs is quoted. “Due to the war, there has been little research carried out… but now we are getting in finally and there is so much to find.

“In some areas there are literally fossils sticking out of the rocks, it is like a museum in the ground.”

In the past, most people who went to Angola were searching for oil, diamonds or landmines.

Now, the country is also proving a big draw for fossil hunters — known in the scientific community as palaeontologists — who have described Angola as a “museum in the ground”.

Angola was closed off for many years because of its three-decade long civil war, which only ended in 2002, so few scientists have had the chance to visit.

We believe there are more dinosaurs to be found, we just need the facilities and means to dig for them

Those getting the chance now are not leaving disappointed. Louis Jacobs, of the Southern Methodist University in Dallas, says:

“Angola is the final frontier for palaeontology. Due to the war, there has been little research carried out… but now we are getting in finally and there is so much to find.

“In some areas there are literally fossils sticking out of the rocks, it is like a museum in the ground.”

Fossil-hunter heaven
Louis Jacobs is part of the “PaleoAngola” project whose biggest find to date was in 2005, when five bones from the front-left leg of a sauropod dinosaur were discovered on a cliff at Iembe, around 65 km (40 miles) north of the capital, Luanda.

Jacobs’ work in Angola is jointly funded by the Petroleum Research Fund and National Geographic Society.

A professor in Dedman College‘s Roy M. Huffington Department of Earth Sciences, Jacobs joined SMU’s faculty in 1983. Currently he has projects in Mongolia, Angola and Antarctica. His book, “Lone Star Dinosaurs” (1999, Texas A&M University Press) was the basis of an exhibit at the Fort Worth Museum of Science and History that traveled the state. He is consulting on a new exhibit, Mysteries of the Texas Dinosaurs, which is set to open in the fall of 2009.
