Wednesday, January 8 – The Geology & Minerals of the DeGrussa Copper & Gold Mine

The DeGrussa deposit is the largest copper mine in Australia.  Discovered in 2009 and put into production in 2012, the mine produces 45,000 ounces of gold and 200,000 tons of copper per year.

Shortly after the deposit was discovered, a geologist and mineral collection curator was hired to collect and preserve mineral samples during the development and production of this mine.  This allowed thousands of rare mineral samples to be saved and made available to the research community and the general public.  This material is usually destroyed by modern mining techniques or would typically be crush and destroyed during milling and processing of the ore.

Geologist Dick Weber’s presentation will show us the fabulous copper minerals and beautiful lapidary material that has been preserved.

A Coming Out Party For A Large Stony Meteorite
Time: 2:30 p.m.
Location: Geology 3656

Large iron meteorites are common, big stones are rare. Our atmosphere presents a formidable barrier to large rocks, efficiently transforming boulders into pebbles. But a few survive the fiery plunge.

Dr. Peter Utas reviews the roster of these great intruders, with a short description of several, and introduces a rare survivor, the 15th largest surviving stone. Discovered five years ago, in Mali or Mauritania, this flight-marked 205-kilogram specimen was largely buried, the soil-line still clearly visible.

Dr. Alan Rubin describes the analysis and classification of chondritic stones; naked eye examination of hand specimens gives important clues, but quantitative techniques are needed to avoid being misled. Hand samples of chondrites will be available for examination by attendees.

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.
