Effect of thermal events on maturation and methane adsorption of Silurian black shales (Checa, Spain)

The present work is devoted to the study of the relationship among composition, properties and methane adsorption of selected Silurian black shales from the Bádenas Formation, located near Checa town (Spain). These outcropping samples were collected in a formation, which is not considered as target for shale gas exploration. The clay minerals are predominant in the whole-rock samples and mostly composed of illite (both potassium and ammonium...
