IAS Fellows' Seminar - What make clays in mud volcano antibacterial?

14th October 2019, 13:00 to 14:00, Seminar Room, Institute of Advanced Study, Dr Elshan Abdullayev (French-Azerbaijani University)


Previous studies have shown that clay minerals were used for therapeutic purposes by humans and animals since ancient times. It is known that clay minerals are characterised by sorption properties. Due to these properties, clay minerals can attach different substances and elements to their surface and inter-surface. Clay minerals can also absorb microbes, bacteria and some toxic components. In addition, chemical components of the clays can be toxic for microbes, and can kill them. The study therefore of the origin of clay minerals in different environments is extremely stimulating.

In this seminar, Dr Abdullayev focusses on clay minerals which form in mud volcano environments. It is known that clays from some mud volcanos in Azerbaijan have been used to cure itching and other skin complaints and diseases. However, the properties of healing clays are unknown. Furthermore, the formation mechanism of these clays remains - for the large part – un-investigated.

The origin of the clays from the mud volcanoes is poorly understood. Azerbaijan is a region characterized by a huge amount of mud volcanoes. Different factors could influence the formation of the clay minerals: (i) fluid in mud volcanoes; (ii) source rocks of the sediments; (iii) depositional environment; (iv) amount of organic matter in the sediments. This seminar by Dr Abdullayev argues the different factors.
