For more than 40 years, Stanislav Filatov, Professor at St Petersburg
University, together with colleagues from other research institutions in
Russia, has been studying the mineralogy of scoria cones and lava flows of
fumaroles in Kamchatka. They were formed after two major eruptions of
Tolbachik Volcano - in 1975-1976 and 2012-2013. This territory is unique in
its mineralogical diversity. In recent years, researchers have discovered
dozens of new minerals here, many of which are one-of-a-kind in the world.
聖彼得堡大學教授斯坦尼斯拉夫·菲拉托夫（Stanislav Filatov）40多年來與俄羅斯其
他研究機構的同事一起，研究了堪察加半島的錐礦物學和噴氣孔的岩漿流。它們是在
1975-1976年和2012-2013年兩次Tolbachik火山爆發後形成的。該領土的礦物學多樣性是
獨一無二的。近年來，研究人員在這裡發現了數十種新礦物，其中許多是世界上獨一無二
的一種。
The recent find by the scientists from St Petersburg University, petrovite,
Na10CaCu2(SO4)8, occurs as blue globular aggregates of tabular crystals with
gaseous inclusions. 'The copper atom in the crystal structure of petrovite
has an unusual and very rare coordination of seven oxygen atoms. Such
coordination is characteristic of only a couple of compounds, as well as of
saranchinaite, which was discovered by our colleagues from St Petersburg
University - the research team of Professor Oleg Siidra,' said the project
manager, Professor Stanislav Filatov.
聖彼得堡大學的科學家最近發現，鈉鐵鈣鈉Na10CaCu2（SO4）8是呈板狀晶體的藍色球狀
聚集體，帶有氣態夾雜物。鈣鈦礦晶體結構中的銅原子具有七個氧原子的異常且非常罕見
的配位。項目經理斯坦尼斯拉夫·菲拉托夫教授說：“這種配位僅是化合物的一種，還有
鋰錳礦，這是我們從聖彼得堡大學的同事奧列格·西德拉教授的研究小組發現的。
The mineral consists of oxygen atoms, sodium sulphur and copper, which form a
porous framework. The voids are connected to each other by channels through
which relatively small sodium atoms can move. The scientists have therefore
established that the structural type of petrovite is promising for ionic
conductivity and can be used as a cathode material for sodium ion batteries.
礦物由氧原子，鈉硫和銅組成，形成多孔骨架。空隙通過通道相互連接，相對小的鈉原子
可以通過通道移動。因此，科學家們已經確定了結構型態對離子導電性很有前景的矽藻土
，可以用作鈉離子電池的陰極材料。
'At present, the biggest problem for this use is the small amount of a
transition metal - copper - in the crystal structure of the mineral. It might
be solved by synthesising a compound with the same structure as petrovite in
the laboratory,' said Stanislav Filatov.
目前，這種用途的最大問題是礦物晶體結構中的過渡金屬（銅）含量很少。

The study was conducted by a team of scientists from various research
institutions from all over Russia. Mineralogical diagnostic assessment was
carried out by Lidiya Vergasova, a senior research associate at the Institute
of Volcanology and Seismology of the Far Eastern Branch of the Russian
Academy of Sciences. She is a great expert in the mineralogy of volcanic
exhalations in Russia. Andrey Shablinskii, an associate of the Grebenshchikov
Institute of Silicate Chemistry and a St Petersburg University graduate,
studied the crystal structure of the new mineral type. He described it
together with Sergey Krivovichev, Professor at St Petersburg University, Head
of the Kola Science Centre, Corresponding Member of the Russian Academy of
Sciences. Additionally, Andrey Shablinskii carried out an X-ray phase
analysis and, together with Stanislav Filatov, head of the research team,
Professor at St Petersburg University, identified the optical constants of
the mineral. The chemical composition of the mineral was determined by
Svetlana Moskaleva, a research associate at the Institute of Volcanology and
Seismology of the Far Eastern Branch of the Russian Academy of Sciences.
該研究由來自俄羅斯各地不同研究機構的科學家團隊進行。礦物學評估由俄羅斯科學院
遠東分校火山學和地震學研究所高級研究員Lidiya Vergasova進行。她是俄羅斯火山氣體
礦物學的傑出專家。格雷本什科夫矽酸鹽化學研究所的研究員，聖彼得堡大學的畢業生
安德烈·沙布林斯基（Andrey Shablinskii）研究了這種新型礦物的晶體結構。他與聖彼
得堡大學教授，科拉科學中心主任，俄羅斯科學院通訊員謝爾蓋·克里維霍夫（Sergey
Krivovichev）一起對它進行了描述。此外，安德烈·沙布林斯基（Andrey Shablinskii
）進行了X射線相位分析，並與斯坦尼斯拉夫·菲拉托夫（Stanislav Filatov）一起，研
究小組負責人，聖彼得堡大學教授確定了礦物的光學常數。礦物的化學成分由俄羅斯科學
院遠東分校火山與地震研究所的研究員Svetlana Moskaleva確定。
Despite the fact that most of the recent discoveries of mineralogists and
crystallographers of St Petersburg University are associated with the
Kamchatka Peninsula, scientists discover many new minerals in the most
unusual places. Among the finds in 2008-2017 there are samples from polar
Yakutia, the Kola Peninsula (Kovdor deposit), Israel (the Negev Desert),
Greece, Tanzania, South Africa, Jordan and many others. More information
about these discoveries can be found at the virtual exhibition of the
Mineralogical Museum of St Petersburg University on the IZI.Travel platform.
儘管最近聖彼得堡大學的礦物學家和晶體學家的大多數發現與堪察加半島有關，但科學家
在最不尋常的地方發現了許多新礦物。在2008-2017年的發現中，有極地雅庫特，科拉半
島（科夫多爾礦床），以色列（內蓋夫沙漠），希臘，坦桑尼亞，南非，約旦等地的發現
。
