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.
圣彼得堡大学教授斯坦尼斯拉夫·菲拉托夫（Stanislav Filatov）40多年来与俄罗斯其
他研究机构的同事一起，研究了堪察加半岛的锥矿物学和喷气孔的岩浆流。它们是在
1975-1976年和2012-2013年两次Tolbachik火山爆发后形成的。该领土的矿物学多样性是
独一无二的。近年来，研究人员在这里发现了数十种新矿物，其中许多是世界上独一无二
的一种。
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.
圣彼得堡大学的科学家最近发现，钠铁钙钠Na10CaCu2（SO4）8是呈板状晶体的蓝色球状
聚集体，带有气态夹杂物。钙钛矿晶体结构中的铜原子具有七个氧原子的异常且非常罕见
的配位。项目经理斯坦尼斯拉夫·菲拉托夫教授说：“这种配位仅是化合物的一种，还有
锂锰矿，这是我们从圣彼得堡大学的同事奥列格·西德拉教授的研究小组发现的。
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.
矿物由氧原子，钠硫和铜组成，形成多孔骨架。空隙通过通道相互连接，相对小的钠原子
可以通过通道移动。因此，科学家们已经确定了结构型态对离子导电性很有前景的硅藻土
，可以用作钠离子电池的阴极材料。
'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，这种用途的最大问题是矿物晶体结构中的过渡金属（铜）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.
该研究由来自俄罗斯各地不同研究机构的科学家团队进行。矿物学评估由俄罗斯科学院
远东分校火山学和地震学研究所高级研究员Lidiya Vergasova进行。她是俄罗斯火山气体
矿物学的杰出专家。格雷本什科夫硅酸盐化学研究所的研究员，圣彼得堡大学的毕业生
安德烈·沙布林斯基（Andrey Shablinskii）研究了这种新型矿物的晶体结构。他与圣彼
得堡大学教授，科拉科学中心主任，俄罗斯科学院通讯员谢尔盖·克里维霍夫（Sergey
Krivovichev）一起对它进行了描述。此外，安德烈·沙布林斯基（Andrey Shablinskii
）进行了X射线相位分析，并与斯坦尼斯拉夫·菲拉托夫（Stanislav Filatov）一起，研
究小组负责人，圣彼得堡大学教授确定了矿物的光学常数。矿物的化学成分由俄罗斯科学
院远东分校火山与地震研究所的研究员Svetlana Moskaleva确定。
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.
尽管最近圣彼得堡大学的矿物学家和晶体学家的大多数发现与堪察加半岛有关，但科学家
在最不寻常的地方发现了许多新矿物。在2008-2017年的发现中，有极地雅库特，科拉半
岛（科夫多尔矿床），以色列（内盖夫沙漠），希腊，坦桑尼亚，南非，约旦等地的发现
。
