This paper presents a study of the major and trace element compositions of fresh mantle‐derived spinel lherzolite and harzburgite inclusions from Cenozoic alkaline basalt in Mount Lianshan and Mount Panshi, Liuhe County, Jiangsu Province. An estimation is made of the contents of the major elements and some of the trace elements in the primitive mantle source region of the area, from which the authors have obtained MgO/Al 2 O 3 = 7.86. The contents of MgO and Al 2 O 3 are also obtained as 37.58% and 4.78% respectively based on the correlation of MgO‐Al 2 O 3 . Then, the contents of various elements in the primitive mantle are calculated using their regression equations with MgO, and the compositon of the primitive mantle, a basic issue in geochemistry study, is discussed on that basis.
