Now we know that as many as 29 carbon minerals originated with human activities, of which 14 have no recorded natural occurrences. It is fair, therefore, to consider the 14 as the youngest carbon mineral species. Among the 14, candidates for the very youngest include a dozen minerals related to uranium mines. Another notable carbon-bearing […]
In this video Robert Hazen (Carnegie Institution for Science) discusses mineral evolution, mineral ecology, and mineral network analysis. The presentation touches upon some of the questions and themes that drive the Carbon Mineral Challenge and the quest to discover new mineral species.
Leesite, leószilárdite and redcanyonite are three new uranyl minerals discovered growing on the walls of old uranium mines in southern Utah. An alumnus of Michigan Technological University found them. Olds says leószilárdite is a particularly interesting find because of the Carbon Mineral Challenge. The challenge runs through September 2019, with the goal to discover as […]
The Tucson Gem and Mineral Show is the largest show of its kind in the world, attracting thousands of mineral collectors, mineralogists, and everyday rock and mineral enthusiasts. For the second year running, DCO’s Carbon Mineral Challenge will take part in the show, encouraging members of the mineral collecting community from all walks of life […]
Science News interviewed project investigator Daniel Hummer (Southern Illinois University, USA) and physicist Jordi Ibáñez-Insa (Institute of Earth Sciences Jaume Almera, Spain) for their cover story in the 15 October 2016 issue. Read the article here.
A new challenge has scientists searching for dozens of unknown, beguiling crystals Like many abandoned mines, the Eureka uranium mine in northern Spain is a maze of long, dank tunnels. Water seeping down the walls carries dissolved substances that percolated through rocks overhead. As the water evaporates into the tunnels’ cool air, some of those […]
Carbon Mineral Challenge Update, August 2016
This summer the International Mineralogical Association’s Commission on New Minerals, Nomenclature and Classification approved two new carbon minerals, leószilárdite and ewingite. The new minerals were described by Travis Olds and colleagues, and bring the total number of new carbon minerals found since the launch of the Carbon Mineral Challenge in December 2015 to six. See […]
Carbon Mineral Challenge Update, April 2016
In December 2015, when researchers boldly predicted that 145 carbon minerals remained undiscovered on Earth, they understood the challenges of finding them. As small as a grain of sand, as ephemeral as a volcanic eruption before a rainstorm, missing carbon minerals are often elusive. Hence the impetus behind the Carbon Mineral Challenge. Such is the […]
“Carbon mineral ecology: Predicting the undiscovered minerals of carbon,” published in American Mineralogist, is now available for download from the University of Arizona Department of Geosciences Website. The Carbon Mineral Challenge was launched as a result of the research in this paper. Visit this page to see a listing of carbon minerals verified since December […]
Mercury has been found to have a dark side with graphite, a crystalline form of carbon commonly found in pencils, being the source of the mysterious dark colouration of the planet’s surface. Dr Helen Maynard-Casely, an Instrument Scientist from the Australian Nuclear Science and Technology Organisation, who was not involved in the study, said the study […]
Mercury has been found to have a dark side with graphite, a crystalline form of carbon commonly found in pencils, being the source of the mysterious dark colouration of the planet’s surface. The study, published this week in Nature Geoscience, was led by a team from the Johns Hopkins University Applied Physics Laboratory in the […]
Más de 2.500 especies que se encuentran en cinco o menos lugares de la Tierra y son testigos de su historia aparecen en un nuevo inventario geológico MADRID.- Calcio, silicio y oxígeno son algunos de los elementos más comunes en la Tierra, pero en ciertas circunstancias se han combinado para formar la hatrurita, uno de […]
In two recently-published papers Dr. Robert Hazen and colleagues estimated that more than 1,500 mineral species remain undiscovered. And, of the roughly 5,000 known mineral species, about 8% (406) contain carbon elements. In a mineral, the presence of carbon — the stuff of plant and animal life — is the multi-billion year mash-up result of […]
