Hybrid In person / Online Meeting – “Turquoise, Just the Facts & Sale”

Turquoise is one of the most beloved, varied & imitated stones in the gem world. Much ado is made of mine origin, rarity, folklore and other intangible attributes that inflate its value. But really what IS turquoise, that glorious gem so beloved that we use its name to describe the color it bears?

Our program will discuss the tangible attributes of “Sky Stone” skipping past the folklore and disregarding the mine origins (or attributions) that cloak turquoise in a fog of intimidating mystery.

Let’s take a real look at the real deal, and a few kissing cousins & beautiful imposters too.

This is a program that is best experienced in person, as much of the material discussed will not be perceptible to online viewers.

OGMS has a nice stock of turquoise and related gems to compare and contrast, and some will be available for purchase after the program.

Hope to see all of you at:

Oxnard Performing Arts Center
800 Hobson Way,
Oxnard, CA

Sunday, April 21, 2024 – 2:30 p.m. 

Presentation:  “Chondritic Porous Interplanetary Dust Particles: A Window into Processes in the Solar Protoplanetary Disk”
Lecturer: Prof. George Flynn, SUNY College at Plattsburgh

Chondritic Porous Interplanetary Dust Particles (CP IDPs), collected by NASA from the Earth’s stratosphere since the 1970’s, never experienced the thermal or aqueous processing, shock or gravitational compaction that affect most other samples of extraterrestrial material. As a result, these CP IDPs preserve a record of early Solar System processes and products, recording many of the conditions in the Solar Protoplanetary Disk during the interval of grain formation and dust aggregation. These highly porous CP IDPs are weak and would likely not survive atmospheric entry as meteorite-size samples. A single ~10 μm CP IDP is an aggregate of many thousand individual grains, most submicron in size, making it necessary to study these surviving remnants of Solar System formation at the nano-scale to reveal the secrets they contain. Constraints on the temperature, composition and processes in the Solar Protoplanetary Disk as grains were condensing and dust was forming will be discussed.

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

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

$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.
