Malibu Hills Agate w/ Marcasite Inclusions

Wednesday, April 3 – Iris Agates – What, Where and How

Iris agate features very fine banding that shows rainbow effects when lit from the right direction. Iris agate is found at sites around the world, including Acton, Malibu, Nipomo, the Owls Head Mountains and the Little Chuckawalas.  It can form in nodules, seams, amygdals, wood casts and more.  Jason Badgey, the founder of California Agate Gallery, will cover how to look for iris agate as well as cutting and polishing for maximum color.  The public is welcome to join us at 7:30 p.m. for this free  presentation.

Analyzing Apollo Moon Samples
Time: 2:30 p.m.
Location: Geology 3656

Lecture by Dr. Dimitri Papanastassiou

Dr. Dimitri Papanastassiou, an expert in isotopic geochronology, recently retired from JPL. The Apollo Program was a competitive race to the Moon. Science was inserted quite late. But, once inserted, it resulted in a revolution in planetary science, in the development of a wide range of new analytical techniques and of new ways to think about planetary evolution, including the Earth. Funding for planetary science became plentiful for a few years; it allowed the formation of multidisciplinary teams. I was finishing my Ph.D. in Physics when the Apollo 11 samples came back and had the excitement to work on them starting in September, 1969 I had developed a mass spectrometer uniquely capable of measuring lunar samples. I attended the 1st Lunar Science Conference, on a very cold day (Jan. 5, 1970) as a newly-minted Ph. D. and continued to work on samples from every Apollo mission. I will share the excitement and serendipity, as well as the importance of the multidisciplinary approach (physics, chemistry, geology). For more info visit: http://www.meteorites.ucla.edu

National Park Service

Death Valley National Park Fossil Thieves

$1,000 Reward – Death Valley National Park

Fossil Thieves stole several fossilized footprints, which had been left in a lakebed by mammals and birds, were missing. Now, Ryan F. Mandelbaum reports for Gizmodo, the National Park Service is asking for the public’s help in identifying a group of backpackers who may have information on the ancient tracks.  In a statement, the National Park Service released the photos of three men who might have witnessed the crime or have knowledge about the disappearance of the footprints. Investigators are offering an award of up to $1000 “for information leading to the identification, arrest, and conviction of those responsible,” the statement reads. According to Mandelbaum, investigators are planning to interview visitors who frequented the Park at the time of theft, in the hopes that someone will be able to provide valuable clues.

Destroying—or pilfering—the property of national parks is prohibited by law. “It’s illegal to collect fossils, rocks, or anything else in National Parks,” Park Superintendent Mike Reynolds said in a statement about the fossil thefts. “The purpose of National Parks is to conserve the landscape and everything it contains for the next generation. I ask that visitors come and enjoy all there is to see, and to leave it unimpaired for others to enjoy.”

The National Park Service has asked anyone with information about the stolen fossils to call the Investigative Services Branch at 1-888-653-0009.
