Uranpyrochlore (of Hogarth 1977)

Uranpyrochlore (of Hogarth 1977) or Ellsworthite (Ca,U)2(Ti,Nb,Ta)2O6(OH) is a rare earth mineral mostly found in the northern parts of North America. It is a uranpyrochlore and is named after Hardy V. Ellsworth of the Canadian Geological Survey by Walker and Parsons. Ellsworthite is also known under the name {Betafite}. It is a very U and Th rich mineral, which in fact makes it slightly radioactive. U makes up about 17.1% of the mineral.
