SOME RADIOACTIVE MINERAL OCCURRENCES IN CARDIFF AND MONMOUTH TOWNSHIPS, HALIBURTON COUNTY By S.E. Wolfe and Nelson Hogg. INTRODUCTION AND ACKNOWLEDGMENTS The writers spent two weeks, from July 8 to J , In Cardiff and Monmouth townships, Hali burton county, investigating reported discoveries of radioactive minerals. but the radioactive mineral suite was known. In these cases the probable radio-active elements were determined from the chemistry of the radioactive minerals present. For example, if the mineral monazite ((Ce, La, Nd) PO4) is the only mineral mentioned in an occurrence description_ the elements present are assumed to be thorium and rare earth .

Nine hundred and sixty-five natural radioactive occurrences of uranium, some containing thorium, are known for Arizona. Of these, localities were the source of l8.l million pounds of U between and About 43 million pounds .

Uraninite. Uraninite is a highly radioactive and interesting mineral. It is the chief ore of uranium and radium, which is found in trace amounts. Helium was first discovered on the earth in samples of uraninite. Radium and helium are found in uraninite because they are the principle products of uranium's decay process. The most common ore mineral of thorium is monazite [(Ce,La,Nd,Th)PO 4], a common accessory mineral occurring in small amounts, a percent or less, in granites and related igneous rocks. This monazite can contain several percent ThO 2 substituting for light rare earth elements (LREE). Other primary ore minerals of thorium are thorianite [ThO 2] andFile Size: KB. The most common radioactive minerals include uraninite, thorite, uranothorite, REE-bearing minerals, secondary alteration products (uranophane) and accessory mineral phases. Episodic exploration and development in the area dates back to , with a mids peak in activity following airborne and ground scintillometer surveys.
