“…American Petroleum Institute (API) is a standard for measuring the natural radiation recorded by various gamma ray counting devices. The standard is a calibration test pit at the University of Houston where a radioactive cement calibrator is assigned a value of 200 API, conceived so that typical midcontinent shale would read about 100 API (Doveton and Merriam, 2004). …”

“…The high U/Th ratios in this interval may therefore indicate conditions of maximum flooding (cf. Lüning et al 2003, Doveton & Merriam 2004, Halgedahl et al 2009), which is supported by the relatively distal, fine-grained carbonate facies in the corresponding interval. The passage to the conglomerates of the Smuggler's Cave Formation at~2 m is associated with a sudden increase in K and Th concentrations and decrease in U concentrations and U/Th ratios.…”

“…Intervals with high U/Th ratios are therefore in some cases interpreted as maximum flooding surfaces (cf. Lüning et al 2003, Doveton & Merriam 2004, Halgedahl et al 2009). …”

“…Poměr Th/K je v rámci pelitických sedimentů využí-ván k identifikaci některých jílových minerálů, případně zastoupení slíd a K-živce (Doveton -Merriam 2004). Relativně nízké až normální hodnoty tohoto poměru (sensu Rider 1996) ukazují na proměnlivou mineralogii spodnobadenských jílů.…”
