Abstract:
Frequency of igneous rock formation in Linyi sag have been divided into five periods according to reference standards such as mineral composition, isotopic age, leap relation between intrusive rock and faults and the electrical cycling of internal igneous rock. This paper describes its characteristics in each stage and respectively analyses its distribution in Ek-Es4, Es3-Es2, Es1-Ed periods. At the end of this paper, the supplemental correlation between the distribution and formation of igneous rock and faults has been carefully explained.
