Abstract
Detailed investigations on Radioelements occurrences in rocks in Kakuri Area Kaduna North West Nigeria were carried out in this work using Geochemical ground follow-up methods. The methods employed include Atomic Absorption Spectrometric (AAS) and Assay of rock samples from the area. Fresh rock samples were collected with hammer and identified as follows: Granite gneiss, Granite, Migmatites and Gneiss. Analysis was made on the powdered rock samples and histograms were plotted to determine the activity of Radioelement concentrations: Potassium, Thorium and Uranium in each of the samples analyzed. Results of the investigations showed high concentration of potassium (40K) and other Radioelements, thorium and uranium in the area. Generally, the results delineate the three Radioelements in terms of their anomaly pattern within the study area.Keywords: Geochemical Survey; Aeroradiometric Anomaly; Fresh Rocks; Radioelements and Kakuri Area

The specific geochemical method which was used for this research is Atomic Absorption Spectrometry (AAS) and Assay of Rock Samples
Summary
Geochemical techniques are generally integrated with geophysical surveys. Several factors contributed to the rapid development of geochemical prospecting during 20th century (Ancher and Main, 1971). It was found that most metallic mineral deposits are surrounded by halos of abnormal trace elements concentration in the adjacent and enclosing rocks. Precise and rapid methods of chemical analysis suitable for the detection of low concentrations (a few parts per million, or even parts per billion) of elements and compound in natural media were developed (Derry, 1971). These methods include use of the Atomic Absorption
