(Table 1) Mean grain sizes and standard deviations of gas hydrate samples

Methane hydrates are present in marine seep systems and occur within the gas hydrate stability zone. Very little is known about their crystallite sizes and size distributions...

Carbon and oxygen isotope compositions of fibrous cement from Black Sea seeps

Carbon and oxygen isotope compositions of fibrous carbonate minerals were measured by an isotope ratio mass spectrometer. The results suggest that the fibrous Mg calcite from...
