Shungite has applications in construction technologies. [13] The presence of fullerenes has resulted in shungite being of interest to researchers as a natural reservoir, though shungite is not uniquely enriched in fullerenes compared to other carbon-rich rocks. [14] Shungite has been used as a folk medical treatment since the early 18th century.
The Zazhoginskoe field is one of the largest fields of shungite rocks in the world. [1] It is located on the outskirts of the village Tolvuya in Medvezhyegorsky District of Karelia, 1.7 km from the shore of Lake Onega, 5 km from a navigable bay. Shungite rocks were deposited around the northern part of Lake Onega and under the lake.
This is a list of notable tar pits throughout the world. Tar pits, which are often covered with dust and leaves, can trap animals that step into them. Over time, the skeletons of such animals become preserved as fossils. Some of the largest deposits of fossils exist within tar pits.

In late 2020, the appearance of a series of metal columns was reported internationally. Referred to as "monoliths", these sheet metal structures began to be constructed in the wake of the discovery of the Utah monolith, a 3 m (9.8 ft)-tall pillar made of metal sheets riveted into a triangular prism, placed in a red sandstone slot canyon in northern San Juan County, Utah.
Fossils may be found either associated with a geological formation or at a single geographic site. Geological formations consist of rock that was deposited during a specific period of time. They usually extend for large areas, and sometimes there are different important sites in which the same formation is exposed.

The crystals are rarely found and the form is usually massive. It has a Mohs hardness of 5.5–6.5 and a specific gravity of 2.75–2.80. It is mostly translucent. Sugilite was first described in 1944 by the Japanese petrologist Ken-ichi Sugi (1901–1948) for an occurrence on Iwagi Islet, Japan, where it is found in an aegirine syenite ...
