In a paper published by American Mineralogist, scientists report the first application to mineralogy of network theory (best known for analysis of e.g. the spread of disease, terrorist networks, or Facebook connections). The results, they say, pioneer a way to reveal mineral diversity and distribution worldwide, mineral evolution through deep time, new trends, and new […]
Scientists searching for everything from oil and gas to copper and gold are adopting techniques used by companies such as Netflix or Amazon to sift through vast amounts of data, a study showed on Tuesday. The method has already helped to discover 10 carbon-bearing minerals and could be widely applied to exploration, they wrote in […]
Mineralogists have long studied how and why minerals occur where they do. Now, they’re applying big data to the question. The researchers are using network theory to understand the complex way different chemical, biological, physical and geographic parameters determine where minerals occur. Network theory – the idea that the relationships between things are governed by […]
OSLO (Reuters) – Scientists searching for everything from oil and gas to copper and gold are adopting techniques used by companies such as Netflix or Amazon to sift through vast amounts of data, a study showed on Tuesday. The method has already helped to discover 10 carbon-bearing minerals and could be widely applied to exploration, […]
We know of about 5,200 mineral species, each of which has a unique combination of chemical composition and atomic structure. There are millions of mineral samples housed in museums, warehouses, universities or private collections, many of which have been neatly described and cataloged. For instance, it’s standard practice for a mineral sample to be tagged […]
Until recently, scientists didn’t have the necessary modelling and visualization tools to capitalize on these giant stockpiles of information. Network analysis offers new insight into minerals, just as complex data sets offer important understanding of social media connections, city traffic patterns, and metabolic pathways, to name a few examples. “Big data is a big thing,” […]

Long ago, in Russia’s distant Northwest, a bird pooped. But this was not just any old splat of excrement. The feces landed on a very hot rock. It lay atop an underground coal fire. The intense heat quick-baked the poop. And that caused one of the substances previously dissolved in the feces to crystallize. With […]
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 […]
