Abstract: This paper discusses systemalically the types of inclutions in carbonate rocks,the distinction between primary and secondery inclutions,and the application of ancient temperature measured by method of "homogenized temperature" in the light of practice.Moreover,it also describes the characteristics of organic inclutions and their variation measured in "homogenized temperature"technigue.Primary and secondery inclutions are of environmental significance because the stages of their formation,order of priority the compositions and homogenized temperature are different.Consequently,distinction between primary and secondery inclutions turns to be a basis for inclution study.This paper introduces the methods of distinction between both inclutions according to morphology of the inclutions in combination with their diagenesis.On the basis of this,the temperature measured by"homogenized method"should obtain its rational interpretation and application.Inclutions in carbonate rock have various features which are closely related to geological environment where they occured and properties of traped fluids.Different liquid gas radio of inclutions and their abundance represent the different environment of the inclution formation.A bundance,colour and variation of organic inclutions not only reflect the quantity to a certain extent,but also the extent of oxidation of the organic matter.This paper gives a primary disccusion and description of the above-ment-ioned points taking the regions of Chishui,Guizhou and Baishai,Guanxi as actual examples.
