Williston basin rewards explorers

(Richard B. Wells)

The recent discovery of prolific limestone mounds in the Lodgepole Formation beneath Dickinson, North Dakota, has started one of the most exciting domestic exploration plays in several years. These features, called Waulsortian Mounds can be found on the surface in central Montana and in the subsurface of Alberta, Saskatchewan, and Manitoba. They may also be present elsewhere around the flanks of the basin.

Tritium

Tritium, a radioisotope of hydrogen with the gross atomic mass of 3.014, is considered an important and versatile radioisotope among twenty five hundred radioisotopes discovered mainly by nuclear transmutation reactions during the last sixty years. A radioisotope can be depicted by its atomic number or chemical symbol and by its mass number that indicates the total number of protons and neutrons in the nucleus of the radioisotope. Thus tritium can be depicted as hydrogen-3.
