Brief information is given about the samples of vernadite from the mineralogical collection of the Earth Science Museum, which were passed for display at the exhibition organized for the anniversary of V.I. Vernadsky. The history of the discovery and studying of vernadite and features of its chemism, modern concepts of its crystal structure, genesis as well as some practical applications are addressed. Attribution of the exhibition samples as vernadites is questionable due to the lack of information about their instrumental diagnostics.

Main areas of work of the group of collections of the Earth Science Museum of MSU are reflected in the article from its inception to the present: the history of foundation, the composition of collections and the main areas of activity for acquisition, study, storage and accounting of collections. Features of the collection work in natural history museums are considered.

The article analyzes a collection of minerals and rocks compiled in 1911 in Yekaterinburg city in the mineralogical workshop of the Commission for the Dissemination of Natural Science Knowledge of the Ural Society of Natural Science Lovers, stored in the Museum of Scientific Heritage (Ulan-Ude city). It includes both material (stone samples) and written sources (handwritten and printed). It contains information on the history of science, education and museum work in our country in the first decades of the 20th century. The collection was compiled according to J.D. Dana’s mineralogical systematics, typical for museum practice of that period. Its geography covers mainly the Southern Urals, but individual samples were collected in other regions of the Russian Empire.
The collection box contains its catalog, as well as scraps of the newspaper “Russkoye Slovo” and a fragment of a note of 1911, confirming the dating of the collection. The autograph on the catalogue belongs to Nadezhda O. Sharakshinova, a famous folklorist, through whose family the collection came to Buryatia. A second autograph was presumably left by the Yekaterinburg merchant Pyotr I. Yarinsky (~1868–?).
The educational mineral collections of the Ural Society of Natural Science Lovers were in demand by educational institutions across the country in the first decades of the 20th century. This activity is presented in sufficient detail in archival documents and research works. However, very few such educational aids have survived in museum collections. For the Museum of Scientific Heritage, the collection is an opportunity to expand the mineral diversity and geography of its collection; a document that stands out for its historical, scientific and memorial value.

The article analyzes geotourism perspectives based on natural history museums. Significant trends for the integrated development of geotourism and natural history museums are formulated. These trends allow revealing prospective views on the tourist potential of the territory. In order to clarify the geotourism development potential at the place of the Earth’s geochronological key stages, several museums were analyzed in conjunction with the geotoponyms of geological systems in the world. A geoheritage interpretation model, correlating ex situ museums and in situ objects, is developed. It includes territorial aspects and substantive formats of interpretation, depending on the target audience and the format of interaction with geoheritage. Geoheritage evaluation includes three groups of criteria (scientific, educational and geotourism), each being estimated to summarize approaches for the museum representation. The criteria are ranged according to the comparison purpose of in situ and ex situ forms. The variety of geoheritage interpretation forms allows suggesting recommendations for geotourism development. One symbolically significant way is the museumification of in situ and ex situ objects to correlate the museum network and the network of protected areas as a complex tourist infrastructure. For the Perm Region as a historically significant place of the Permian geological system discovery, the priority is to develop a complex plan to integrate the possibilities of geoheritage representation through museum forms and in the natural environment. In view of the objective scientific data, the Perm Region has no GSSP of the Permian system; therefore the role of the “symbolic stratotype” should have the Permian Period Museum as the basic object of the geotourism infrastructure and the starting point of tourist routes. The supportive role in the Permian geoheritage preservation and representation belongs to the network of municipal and university museums.

Here is a brief overview of the author’s lecture series — an additional general education program “Mineralogical Journey into the Depths of the Earth and Back” dedicated to minerals characterizing the main layers of the Earth, namely: the crust, the upper and lower mantle, and the core. The Program provides a general understanding of the Earth’s structure and minerals, their main properties, and natural formation processes. It covers key minerals of the Earth’s crust such as quartz, gemstones like ruby, sapphire, emerald, etc., as well as mantle minerals, including diamond. Information on the application of these minerals in technology and the jewelry industry is also presented. During the preparation and conduction of the online course, the author implemented an individualized approach, which helps enhancing the learners’ understanding and increase their satisfaction. This course was developed by the author and piloted at the Earth Science Museum of Moscow State University named after Lomonosov. To facilitate the absorption of a large amount of information, the series is divided into four sessions and clearly structured within each one. The online format enables the lecturer to interact fully with the audience at any time convenient for the participants.

Brief information about the author’s course dedicated to crystal growth is provided. The education program gives general information of the mechanisms of crystal growth, the main growing methods, crystal formation in nature and under home conditions. Issues of the origin of the first group gemstones, the specifics of their formation in the laboratory, methods of treatment and application are considered. A large amount of information is given, that’s why the course is divided into four sections and clearly structured within each of them. This helps to make it easier to perceive. Online course design allows the lecturer to effectively interact with the audience.

Brief information about the author’s course dedicated to the world of gemstones is provided. Data of first-order gemstones (diamond, emerald, sapphire, ruby, alexandrite and pearl) are given. The questions of the discovery history of these gemstones, their classification, properties, formation in nature, methods of synthesis, methods of refining, as well as estimation systems are considered. Due to a large amount of information, the course is divided into four sections and clearly structured in each of them. This helps to make it easier to perceive. Online course design allows the lecturer to effectively interact with the audience.

The palaeoichthyological collection from the Bilovo locality in the Tver’ region (Famennian of the Main Devonian field), currently housed at the Andreapol Museum of Local History, is continued to be studied. Placoderm fishes of the family Bothriolepididae Cope predominate in the ichthyocomplex of this locality. Rare plates of large-bodied Bothriolepis sp. with a flattened armor were found at the Bilovo locality in clay deposits in addition to numerous remains of crested bothriolepidids. The material on Bothriolepis sp. is represented by three posterior medio-dorsal plates only. These plates are described, figured and compared with a similar material on Late Devonian bothriolepidids from the Main Devonian field and other regions. A brief characteristic of the Bilovo locality is given as well.
