A Case for Daub: Both Scientifically and Culturally

May 12, 2020

Shelby Jones' presentation A Case for Daub: Both Scientifically and Culturally has been postponed until further notice.

In recent decades, there has been a concerted effort to understand the subtle variations in Earth's magnetic field over the past three millennia. This motivation has led to a worldwide effort to increase the quantity, improve the quality, and increase the temporal and spatial diversity of archaeomagnetic records. Unfortunately, the success of these goals is limited in most regions (specifically in California), due to a lack of magnetically suitable material that spans space and time continuously. Recent experiments on burned daub (similar to adobe) from structures at archaeological sites suggest that it is a viable magnetic-carrier with the added benefit that the adhering soot can be dated with radiocarbon, directly dating the age of the burn.

The Brown Bag talks are held in the OAS conference room at the Center for New Mexico Archaeology. Talks are informal (and you can bring your bag lunch). Usually, seating is adequate, but we have had 80-plus people show up for a talk in a room that can only hold 35. Seating is available on a first-come-first-served basis. Admission is free.

The Center for New Mexico Archaeology (7 Old Cochiti Road) is located off of Caja del Rio Road, across from Challenge New Mexico on the way to the Santa Fe Municipal Golf Course. Take 599 to South Meadows Road, continue through the traffic circle west along the Frontage Road to Caja del Rio Road. CNMA is on the left-hand side of the road and is the large building with white sail-like skylights on the roof.
