The Natural History Museum in London is currently showcasing a captivating mineral known as Aerinite, a discovery originating from Morocco that underwent scientific analysis nearly three decades ago. This rare specimen, distinguished by its striking deep blue color, is prominently displayed within the museum's mineral gallery, highlighting the institution's commitment to unveiling geological wonders.
This mineral specimen was acquired in the 1980s near the city of Fes, thanks to the efforts of science journalist and geologist Anna Grayson, who donated it to the museum in 1996. At that time, a team of experts, led by mineralogist Gordon Creasy, faced challenges in accurately identifying the rock's composition, with some speculating it might be a mysterious and unknown mineral.
After years of meticulous analysis, researchers confirmed that the specimen belonged to a rare mineral known as Aerinite, a silicate containing carbonates. The discovery of this mineral dates back to 1980, when Grayson purchased the stone from a street vendor along the route south of Fes, initially believing it to be lapis lazuli. However, the stone's electric blue hue piqued Grayson’s curiosity, prompting her to retain and study it further.
Grayson recalls that the unique shade of blue was the first aspect that captured her attention, alongside the presence of sloped surfaces resembling geological features associated with rock slip. The Natural History Museum emphasizes Morocco's exceptional geological diversity and rich mineral deposits, making it a favored destination for scientists and mineral collectors from around the globe.
When the specimen was presented at the museum during an open day focused on identifying rocks and minerals, the research team embarked on a series of scientific analyses that spanned over a year. According to museum researcher Paul Schofield, the mineral generated significant excitement among scientists, stating that understanding its unique properties required collaboration with various laboratories and the use of advanced analytical techniques.
Through synchrotron X-ray analysis, researchers were able to ascertain the mineral's intricate structure, which consists of millions of finely woven crystal fibers. Within these fibers, electrons move between two types of iron atoms, imparting the stone with its distinctive blue luster. The complete atomic structure of Aerinite was not unveiled until 2004, thanks to a research team led by Spanish scientist Jordi Rius.
Studying this specimen, which is among the largest samples of Aerinite analyzed by the museum, has also facilitated the identification of similar minerals within various scientific collections. Today, this "blue stone" is on display in the minerals gallery of the Natural History Museum in London, which houses some of the rarest mineral specimens in the world.
For Anna Grayson, witnessing this mineral showcased to the public represents a significant moment, reinforcing her belief that mineralogy is “a science filled with beauty and wonder that forms the foundation of the materials that build our modern world.” Through this exhibition, the museum also highlights Morocco’s contributions to the discovery of geological treasures that continue to fuel international scientific research.
The museum's growing interest in Morocco stems from its geological and fossil wealth, with researchers from the museum and the University of Birmingham recently discovering new fossils of a dinosaur named Spikeomelus in the Boulemane region, dating back approximately 165 million years. This dinosaur is characterized by a unique armor made of plates and giant spikes, some reaching a meter around its head, while others were directly fused to its ribs—a distinctive feature among vertebrates.
Researchers believe that this discovery represents one of the best-known skeletons of ankylosaur dinosaurs from the Middle Jurassic period. A subsequent study published in the journal "Nature" revealed that this species possessed a tail weapon millions of years ago, contrary to previous scientific beliefs. This research was conducted in collaboration with the University of Fes, following an initial discovery made by a local farmer, reflecting Morocco's vast scientific potential and underscoring the necessity to protect these sites of significant scientific and historical value.
