✦ Synopsis

The performance of a noble gas mass spectrometer used for K/Ar-Ar/Ar dating has been improved in three ways. The background has been decreased by surrounding the ion source with a cylinder of St707 NEG strip. A simple method has been found for rotating the sample during irradiation in the nuclear reactor. Finally, a furnace that does not require the use of an additional vacuum system has been constructed for degassing the irradiated samples.

Hossere Nigo is one of several anorogenic plutonic complexes in the north-eastern part of the Cameroon Line (CL), West Africa. It is a dominantly gabbroic ring structure with a core of monzonitic to syenitic intrusive bodies. Previous geochronological work in the CL indicates a time span from 67 to
