The Del Air Rockhounds Club Welcomes You!!





www.Facebook.com/DelAirRockhounds


The Del Air Rockhounds Club was founded in 1952 with members mostly residing in the San Fernando Valley area of California. Our club is a non-profit organization dedicated to sharing knowledge of the lapidary arts and techniques, geology, mineralogy and related fields. We own our own lapidary equipment with members available to teach and demonstrate lapidary techniques to other members. Our members enjoy lapidary related programs, demonstrations, exhibitions, displays and lectures. We also take monthly field trips to our local deserts & mountains for exploration and the study and collection of lapidary and mineral specimens.

March 2018 Program:
“Natural Radiation in Rocks and Our Surroundings”
Presented By: Duane Doty
Professor Doty is a relic of the California Land Grand system attending Ventura JC in 1957 and then earning a doctoral degree from UCLA in 1966.  There at the Cyclotron he studied several new isotopes of Palladium and Silver which you will probably never hear of again. Using the Engineering Nuclear Reactor for neutron scattering was a special privilege. Then in 1966 he started teaching at the San Fernando State College which was surrounded by orange trees.  He became tenured and was granted the outstanding teaching award. 

Teaching was his first love, always 40+ hours a week at school with the students.  However, he did some part time research for the government at the Naval Civil Engineering Laboratory in Hueneme during the summers.  They were using the dD and dP reactions in an electrostatic accelerator to mimic the radiation from a hydrogen bomb.  Later at Atomic International at the Santa Susannah Field Laboratory, he was a consultant measuring fast neutron spectra from an experimental fast reactor.

Professor Doty will demonstrate several alpha, beta and gamma detectors used at the CSUN Nuclear Physics laboratory. Duane hopes to also show samples of naturally radioactive rocks from his ollection. 

Professor Doty has graciously agreed to test 1 item from each member/guest for radioactive content so please bring in just one (1) item only, be it rock, mineral, Vaseline glass or any other item and we can see if it is radioactive.

California’s Own Dinosaur 
The fossilized skull of a duck-billed dinosaur named Augustynolophus was revealed in a 1943 paleontological excavation in the Panoche Hills of western Fresno County. It consisted of the majority of the skull (including the dentary and predentary), vertebrae, and bones of the limb and hand. A second specimen, discovered in 1939, was made up of elements of the skull and limbs.

These are currently the only two known specimens of Augustynolophus. All known specimens of Augustynolophus have been found only in California. In September 2017, Augustynolophus was declared the official State Dinosaur of California, alongside the saber-toothed cat as the official State Fossil and the California red-legged frog as the official State Amphibian, and Denim, the official State Fabric.

It should be noted that it is one of three known dinosaurs from the western coast of the United States, the other two being the Campanian Aletopelta coombsi and an undescribed species of tyrannosaur from Washington state. However, indeterminate hadrosaur remains have been found throughout California.

Augustynolophus is an extinct genus of herbivorous saurolophine hadrosaur dinosaur, discovered in the Moreno Formation in Fresno, California. Like all species of hadrosaur, Augustynolophus morrisi was an herbivorous dinosaur which had a diet consisting of the plant life in the area. It was specialized to chew its food since hadrosaurs were one of the few known species of dinosaur that chewed its food.

Augustynolophus morrisi, a contemporary of the better-known tyrannosaurus and triceratops, was named for two notable Californians: Gretchen Augustyn and paleontologist Dr. William J. Morris. Just eight states have declared a state dinosaur to pay homage to the long-extinct creatures. Every state has a state bird, and birds are extant dinosaurs. Also, most states and the District of Columbia have state fossils, and nine of those designations are incidentally dinosaurs. However, there are only 11 states plus D.C. that have officially declared state dinosaurs.
