Late Mesozoic-Cenozoic red bed deposit strata in the western Qinling,based upon their rock association,spatial distribution and tectonic deformation characteristics,can be divided into three tectonic sequences.

The morphology of Ni deposit and preferred orientation of Ni grains were also analyzed using SEM and XRD techniques.

Nanocrystalline coatings get more and more attention same as nano-materials because of owning many special physical and chemical quality compared as traditional materials.

It is found that the passage systems of different sequences have difference:(1) The passage systems of deep depositional sequences(Ek-Es4)are characterized by the complex hydrocarbon conduction in the sides of sandbodies.

These Cambrian strata have been grouped, on the basis of sedimentary facies sequences and stacking patterns of depositional sequences, into 63 third order sequences, or 22 second order megasequences and 4 first order supersequences, of which the latest ones represent the depositional cycles with the periods of 200-400 Ma during 1800.

Based on the theory of continental foreland basin combining with petroleum exploration practices,Basijiqike formation reservoir of Cretaceous in Kuqa foreland basin controled by continental depositional sequence has been studied.
