GEOLOGY AND MAGNETIC SUSCEPTIBILITY PROPERTIES OF IPOLE LITHOLOGIES IN EXPLORING FOR DIAMONDIFEROUS KIMBERLITE IN IPOLE SIKONGE DISTRICT, TABORA REGION

ABSTRACT
This project report is the result of the work done at Ipole area, Sikonge District from July
to September 2008. The main objectives of this project was to identify the rock types
present at Ipole area using rock magnetic properties and to determine the presence of
Diamondiferous Kimberlite in Ipole lithologies.The following methods were used to
accomplish the task; Heavy Mineral Sampling in Streams sediments, Loam and Auger
sampling, Airborne magnetic survey, Geographic Information Systems (GIS), Global
Positioning Systems (GPS)/Bathymetric Surveys and Drilling (percussion drilling).
The study of drilling logs and Magnetic Susceptibility reveal the presence of ferricrete,
calcrete, sands, micaceous granite, pink granite, rhyolite, diorite, granodiorite, gabbro and
basalt. This study did not find any indicator minerals for Kimberlite such as
picroilmenite (Mg rich), pyrope garnet, chromediopside and diamond which when found
indicate high proximity to the source, however Ipole appears to be sited within areas of
drainage and transported soil covers, which possibly reflecting zones of preferential
weathering and may be consistent with possible Kimberlite positions.
Radiometric map shows outcropping granite. The relationship between radiometric
signature and Kimberlite mineralization indicate that Kimberlites often present at the
surface as ground depressions. (Yellow-white pixels in the ternary image reflect high
radioelement concentration.) Ipole area is still a highly prospective area with regard to
Kimberlite exploration because exploration has not been adequately carried out in areas
under overburden.
