dc.description.abstract | The mineralogy and paragenesis of fluorite in the
Musgut-Kimwarer are described. The fluorite deposits
occur in various isolated areas. The fluorite deposits
occur within the Basement rocks of the Mozambique Belt
in the Kerio Valley. The mineral has been deposited
from hydrothermal solutions emanating in tension
fractures and along late minor faults. The fluorite
bodies have largely replaced crystalline limestone and
to a minor extent the fault-breccias. There are some
fluorite bodies which have a hypogene origin.
Four coloured varieties of fluorite have been found
in the area, namely white, yellowish-bro.m, dark-grey and
violet varieties. The paragenesis of the different
varieties of fluorite consists of three stages of deposition
which however, appear to have been continuous and gradual. The
study of the paragenesis of the three stages is based
on the apparent stratified form of the varieties of the
fluorite bodies as observed in the field,the crystallization , 1P
temperatures of the associated minerals, aLd complexity of
crystaI forms in the different varieties of fluorite:
white and yellowish-brown varieties were deposited first,
followed by dark-grey one and lastly the violet variety.
The crystallization temperature decreased with the sequence
of deposition in the three stages. | en |
