Meetings

Guests are always welcome at our meetings!  They are held on the first Wednesday of the month (excluding holidays) at 7:30 PM, currently online.  We look forward to resuming our in person meetings at the Oxnard Performing Arts Center (map below).  The format includes an educational presentation, followed by refreshments, and a short business meeting. 

Our Pebble Pup meetings are held on the third Wednesday of the month (excluding holidays) at 6:00 PM – 6:45 PM.

Due to the February 2022 early morning fire at the Durley Park Art Center, our classes will be canceled until repairs are made. 

Wednesday, January 4, 2023 –7:30 p.m. – 9:00 p.m. – Online Meeting – “Urban Rockhounding In Tucson”

Every year the largest gathering of rockhounds, miners, vendors and the general public converge in Tucson to buy, sell and trade everything and anything pertaining to all aspects of our hobby. With nearly fifty shows from which to choose, it can be a bit con-fusing for the first-timer. As the grand finale, The Tucson Gem and Mineral Club hosts the largest, oldest and most prestigious gem show in the world complete with 250 dealers, world class exhibits, lectures and more.

This program is jammed packed with photo highlights from past events including exhibits presented by the Smithsonian, prominent universities and private collections.

You will discover that if you can’t find it in Tucson it probably doesn’t exist anywhere. According to Mary Pat, you will run out of money long before you find all the items on your rockhound wish list. Based on personal experience of attending this event for more than 20 years, Mary Pat will offer practical advice for navigating though the “Tucson experience” to make it both efficient and fun.

The Public is always welcome to join our meetings!

How to join the Zoom meeting:

As always, wearing headphones to prevent microphone feedback is encouraged.

January 15, 2023 – 2:30 p.m. 

Presentation: IIE Irons: The Most Reduced Ordinary Chondrites

Lecturer: Dr. Alan Rubin, UCLA       

IIE irons are the most reduced ordinary chondrites.  Their bulk chemical (e.g., Ir/Ni, Ir/Au, Au/Ni, Co/Ni) and bulk isotopic compositions (i.e., Ä17O and ä74/70Ge) lie along extensions of LL-L-H trends.  Chondrule-bearing clasts in IIE Netschaëvo have mineralogical and petrological characteristics that extend LL-L-H trends; Netschaëvo clasts have lower olivine Fa, low-Ca-pyroxene Fs, kamacite Co and mean chondrule diameter values as well as higher modal metallic Fe-Ni.  Because most Type-I (FeO-poor) chondrules formed before most Type-II (FeO-rich) chondrules, the (Type-I)/(Type-II) modal ratio decreased from IIE to H to L to LL during agglomeration.  Earlier-formed chondrules acquired higher abundances of refractory metal nuggets within CAI-fragment precursors, accounting for systematic changes in bulk OC of refractory/common siderophile and refractory/volatile siderophile ratios (IIE>H>L>LL).  Because more Au and Co than Ni were retained in silicates, loss of metal globules from spinning partly molten Type-I chondrules caused bulk decreases in Au/Ni and Co/Ni from IIE to LL.  Expelled globules had different nebular aerodynamic properties than chondrules and drifted away (accounting, at least in part, for the metal/silicate fractionation).

December 2, 2020 – “Excavating a Fossil Sea Cow on Santa Rosa Island”

Join Dr. Jonathan Hoffman, Dibblee Curator of Earth Science at the Santa Barbara Museum of Natural History (SBMNH), for a look at the excavation and preparation of fossils from ancient seas and what we’re learning from them. Recent reports of fossil sirenians, or sea cows, from Channel Islands National Park have extended the fossil record of these unique marine mammals. In 2017 and 2018, the SBMNH excavated the skull and skeleton of a potentially new species of sea cow on Santa Rosa Island. The fossils from that excavation also include mollusks and crabs that give researchers clues to what the environment was like millions of years ago and how the Santa Rosa sea cow fits into the story of sirenian evolution as they spread around the world.

November 4, 2020 – “Minerals And The Future Of Energy Sustainability”

Aaron J. Celestian, Ph.D. has spent a great deal of his career finding ways to safely separate toxic elements from the environment that are remnants from our energy production, such as nuclear, fossil fuel, and battery. Being able to selectively lock these elements inside molecular holes in crystals, and safely store them in the crystals for the long-term away from living organisms, is a significant advancement. This work is still ongoing, yet newer discoveries have opened the door to using these same minerals to extract critically needed elements from otherwise toxic environments. Celestian is currently looking for new minerals that can selectively absorb these crucial resources, or design new ‘minerals’ when known species do not work.

October 7, 2020 – “Fluorescent and Unique Minerals of Franklin New Jersey”

Geologist Sandy Zucker will discuss the history and geology of this world famous, unique ore deposit and mineral locality, highlight some of the rare minerals found here, or only found here, and take you on a visual tour of the dazzling fluorescent mineral displays found in the mines of Franklin and Sterling Hill.

July 1, 2020 – Rare and Unusual Gemstones of California

California is an extraordinary state for rockhounding.  Geological forces have created one of the widest varieties of rocks and minerals found in any state.  Known as the ‘Golden State’, California has named Gold as its state metal, Serpentine as the State rock and Benitoite as the State gemstone.  This talk will feature benitoite, lapis lazuli and vesuvianite.  Our presenter will be Geologist Walter Lombardo of the Nevada Mineral & Book Company.

June 3, 2020 – “Magical Obsidian of Davis Creek”  7:00 p.m.

We will “open” our doors at 7:00 p.m. to allow our Members to socialize.  We will begin the meeting at 7:30 p.m.  Terry Wilson will show us colorful obsidian collected on the 2018 CFMS trip to Davis Creek, California. Her talk will outline the trip itself, the various types of obsidian found in the area, and include tips for working with obsidian. Terry has exhibited rainbow obsidian in the last two Ventura County Fairs, cabochons showing the cat-eye effect with rainbow obsidian, and rainbow obsidian in the rough, respectively.   Missed the meeting?  See the recording.  https://www.youtube.com/watch?v=9vIRNbley7E

National Park Service

2022 Fee Free Days on Federal Public Lands

Here are the 2022 fee free days offered for recreation sites under the management of the National Park Service and the U.S. Forest Service.  While many parks, facilities and services associated with these agencies are free, some require a fee. Recreation fees, authorized by the Federal Lands Recreation Enhancement Act, enable federal land management agencies to reinvest in the management of various recreation sites.

2020 Fee Free Days

January 17 – Birthday of Martin Luther King, Jr.
April 16
 – Start of National Park Week / National Jr. Ranger Day
August 4 – Anniversary of Great American Outdoors Act
September 24 – National Public Lands Day
November 11 – Veterans Day

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.
