【Abstract】 The carbonate diagenesis and diagenetic environmentare important in both theory and practice. The first part of this paper is devoted to the explantion of the "diagenetic frap ". Diagenesis controls the distrlution of oil and gas. sometimes a new trapis formed by thiess diagenesis. Hence comes the term "diagenetic trap" In the second part, the formation of sedmentary deposits is discussed. There are dissenting views when the geologists talk about sedimentary deposits if they are formed by diagenesis. The authors of this paper argue that some of sedimentary deposare formed by sedimentation, while others are replaced in the diagenesis. It followies that certain sedimentary deposits must be formed by diagenesis.更多还原
