MONAZITE-(Ce) 
Eureka Farm 99 (Stiplemans Mine), 21 Miles WSW of Usakos, Karibib District, Erongo Region, Namibia

The Eureka Farm 99, or Stiplemans Mine, was a Monazite prospect in a carbonatite, formed in a dolomitic marble.  The iron-stained marble host rock produced individual red-brown Monazite-(Ce) crystals, as well as red-brown Monazite-(Ce) cleavages.  Monazite-(Ce) has a well developed parting cleavage which is very obvious in the specimens described below.   No crystallized Monazite-(Ce) is available in this group of specimens.  Monazite-(Ce) is a slightly radioactive REE-bearing mineral with the composition: (Ce,La,Nd,Th)(PO4)
