Abstract

In the geologic history, volcanic ash was commonly associated with organic-rich deposits. Volcanic ash layers (K-bentonites) were deposited extensively within the shale of Wufeng–Lungmachi formations in the Sichuan Basin and its periphery. The complex process of the influence of the related volcanic activity on the depositional environment is discussed in the present chapter.
