INNA has been adopted for multielemental study of an acidic rock (OH-121) and three basic rocks (EH-121, WH-121 and SI-121)
collected from Al-Madina in the Western Region of the Kingdom of Saudi Arbia. The basic rocks have higher concentrations of
the transition elements Ti, V, Cr, Mn and Co, as compared to the acidic rock.

Multielemental analysis of an iron ore from the Kingdom of Saudi Arabia was carried out using Instrumental Neutron Activation
Analysis (INAA) with Ge(Li) detectors. The spectra were analysed with the help of an off-line computer programme. Twenty five
elements are observed to be present in the ore. The elements of major interest are Fe, Al and Ca with 51.5%, 3.6% and 2.2%
