Restoration method and appliction discussion of strata denudation quantity in Qongque river area of Tarim basin

The Kongque river area is located at the Tarim basin Northeast edge,in this area Devonian period-Triassic Period stratum's distribution is limited,the stratum denudation quantity is big,choosing the correct restoration method of stratum denudation thickness is the most important.At present there are many methods used to estimate the stratum denudation thickness at home and abroad.In view of the research area actual material situation,we proposed a set of feasible and suitable denudation quantity restoration method. With the application of the structural cross section combined with deposit thickness extrapolated method,we restored the regional six top denudation thickness of the Cambrian-lower Ordovician,the mid-upper Ordovician,Silurian,Carboniferous, Triassic and Jurassic and analyzed each top denudatoin quantity change rule,which had certain guarding function to the area paleostructure situation and oil-gas exploration research.
