The horizontal and vertical first derivatives of magnetic anomalies of an infinite cylinder are calculated by the cosine transform method, in which the maximum errors are -0.28 nT/m and 0.47nT/m, respectively and the percent errors are generally within -3.57%~3.27% and -1.94%~1.88%, respectively except several data of the boundary and part are bigger because of remains of Gibbus effect. The calculating curve and theoretical curve are approximately coincident, and there is no influence by effective magnetic dip angle in computing. But the errors with the Fourier transform method are -10.62nT/m and 14.42nT/m, there is large departure between the calculating curve and theoretical curve and evident influence by effective magnetic dip angle in computing.

With the rich sediments supplied by the Pearl River, under the paleogeography sedimentary background of Baiyun Sag continuously subsiding, with sedimentary sequences related to relative transgressive sea level change ,contrary to regressive eustasy, the Pearl River Deepwater Fan System has specific evolution characteristics, which left the sedimentary record controlled by peripherical significant geological events. The sharp change of deposition rate and lithologic geochemical characteristics about 23.8Ma sequence boundary demonstratesd that sediment source had changed, perhaps related to the uplift of Tibet plateau and spreading of the South China Sea, which led the paleoPearl River drainage to expand to western China plateau , maybe much broader than present.
