The present disclosure is directed to assaying rock samples (e.g., core samples) for the presence of catalytically-generated gases, such as methane for example. According to one or more aspects of the present disclosure, a method for assaying a rock sample comprises sealing a carbonaceous rock sample in a container having an atmosphere and assaying for a quantity of catalytically-generated gas in the sealed container. The method may comprise generating the catalytically-generated gas in response to a catalytic reaction between the carbonaceous material in the carbonaceous rock sample and a low-valent transition metal that is present in the carbonaceous rock sample. The catalytic reaction may occur in a static atmosphere of the sealed container.
