Clays from the Bulganak volcanic field (Kerch Peninsula) were studied to estimate the possible sources of chemical elements in mud volcanoes. The collected clay samples were analyzed using inductively-coupled argon plasma mass spectrometry on an ELAN 9000 mass spectrometer (PerkinElmer-Sciex, USA-Canada). According to the obtained data, the geochemical specialization of the eruption products was determined. It was identified that Maikop clays in the vicinity of Kerch and in Lisya Bay spaced far from the city have almost identical bulk concentrations of most elements. The concentrations of Ca, V, Cr, Mn, Ni, Nb, Sn, I, and Ba in volcanic clay are 3–23.3 times higher compared to Maikop clays, while Ta concentration is over 2 orders of magnitude higher. Water-soluble compounds predominate in the volcanic clay. Data on a wide range of chemical elements allow us to conclude that the composition of volcanic clay is weakly dependent on the elemental composition of seawater. The concentrations of many chemical elements are hundreds of times lower in oil than in the water extract from the volcanic clay, and the concentrations of most chemical elements in oil are thousands of times less. Elements in the studied objects show the similar decreasing order of their abundance: Fe, Na, Ca, Mg, and Ti. Hence, oil of the Kerch Peninsula insignificantly contributes to the element composition of volcanic clay.

研究了来自 Bulganak 火山区（刻赤半岛）的粘土，以估计泥火山中化学元素的可能来源。在 ELAN 9000 质谱仪（PerkinElmer-Sciex，USA-Canada）上使用电感耦合氩等离子体质谱法分析收集的粘土样品。根据获得的数据，确定了喷发产物的地球化学专业化。经鉴定，刻赤附近和远离城市的 Lisya 湾的 Maikop 粘土具有几乎相同的大部分元素体积浓度。与 Maikop 粘土相比，火山粘土中 Ca、V、Cr、Mn、Ni、Nb、Sn、I 和 Ba 的浓度高 3-23.3 倍，而 Ta 浓度高出 2 个数量级以上。水溶性化合物在火山粘土中占主导地位。关于各种化学元素的数据使我们能够得出结论，火山粘土的成分与海水的元素成分有微弱的关系。许多化学元素在石油中的浓度比从火山粘土中提取的水的浓度低数百倍，而石油中大多数化学元素的浓度要低数千倍。研究对象中的元素显示出相似的丰度递减顺序：Fe、Na、Ca、Mg 和 Ti。因此，刻赤半岛的石油对火山粘土的元素组成贡献不大。并且油中大多数化学元素的浓度要低数千倍。研究对象中的元素显示出相似的丰度递减顺序：Fe、Na、Ca、Mg 和 Ti。因此，刻赤半岛的石油对火山粘土的元素组成贡献不大。并且油中大多数化学元素的浓度要低数千倍。研究对象中的元素显示出相似的丰度递减顺序：Fe、Na、Ca、Mg 和 Ti。因此，刻赤半岛的石油对火山粘土的元素组成贡献不大。
