of Petroliferous 
Basins
in West China
LI, DESHENG
The main petroliferous
basins in West China are compressional in origin, forming in response to
compressions resulting from the collisions of northward moving Indian Plate
to the Eurasia Plate.
Multiple plate collisions resulted
in superimposed basins and hence the formation of multiple hydrocarbon
systems from different assemblages of source, reservoir and caprocks.
Both marine and continental
source beds were deposited and generated hydrocarbons. The marine carbonates
and mudstones of the Paleozoic and the lacustrine mudstones of the Mesozoic
and Cenozoic are good source rocks.
Commercial volumes of oil and
gas have flowed from the carbonate and sandstone reservoirs of the Paleozoic
and from sandstone and conglomerates of Mesozoic and Tertiary age.
Thrust folds, gentle arched anticlines, stratigraphic monoclines and buried hills associated with drape anticlines are common trap styles.
