Abstract:
Since the volcanics has a quite complicated composition,it is difficult to evaluate the content of different minerals in vlcanics by log data.The volcanics of the Jiamuhe Forma-tion of Permian System,5-8 distrcts,Karamay Oilfield is divided into volcanic breccia,basalt and rhyoporphyry based on the data of cross section,and distinguished using cross-plots.The paper also provides the values of density,neutron porosity,cross section index of effective photoelectric absorption and uranium,thorium,potassium contents.
