Study of carbonate rocks of the khuff and Jubaila formations , saudi arabia by Thermal derivatography
MetadataShow full item record
Thermal derivatographic analysis of the Khuff and Jubaila carbonate rocks shows that calcite and / or dolomite (of calcitic type) are the main constituent minerals. Their differential thermal and thermogravimetric behaviours are thoroughly investigated . Textural rock components (sparite , micrite and allochems ) were found to have some effect on the sharpness of peaks and the temperatures at which the reactions take place. Thermogravimetric data are used for the quantitative estimation of calcite and dolomite. The results show very close similarity to those obtained by X-ray diffraction and chemical analyses.
