In this experimental study firstly a sulphur-bearing alkanethiol-derivatised gold nanoparticles has been selected and prepared. The alkanethiol-derivatised gold was put in the mud-stone samples bearing terreau. In varies elevated temperature the gas products were collected by foam plastics in a special installation. The measurements on the contents of gold in foam plastics and on the composition of gas phase were carried out and the comparisons for various samples were made.
