Abstract: Coal researching in east part of China and especially in concealment is regarded more and more.The deposit features of the Quaternary coal bearing stratum in Changyi district of Weifang area,Shandong Province is discussed in this paper.Geological structures are interpreted according to the magmatic intrusion property,coal quality,the data of seismic exploration,and the deposit rule of the coal bearing stratum is concluded.It is inferred that the coal bearing properties in this area are similar with that of Wutu coal field and Huangxian coal field,being a typical Paleogene flu-vial-lacustrine coal bearing faulted basin,and suffered magmatic intrusion actions and the coal rank is high.Finally the southern and the eastern parts are determined as the coal finding target area in the future.
