This paper briefly introduces the basic fact of the existence of the PaleoTethys Ocean in the Lungmu Co-Shuanghu suture, i.e. the ages and natures of Early Paleozoic ophiolites, Permian ophiolites, Devonian-Permian radiolarian cherts, accretionary slabs of different natures, two types of tectonic mrlange zones and covers of ophiolites. The starting time of the Paleo-Tethys Ocean in Qiangtang may be traced back to Early Paleozoic and the records about the oceanic basin evolution persisted from the Late Devonian to Late Triassic.

The size of the diplexer was 18.3mm×15.6mm×0.5mm, at the frequency of 1.87GHz and 2.34GHz, the decay was higher than 55dB, so it suppressed the local oscillator signal and its mage reconstructor tube signal effectively, which met the design of filter with miniaturization. And then the three-dimensional laminated structures were used to realize the design of miniaturization, which was good for the later research.

Aiming at these problems, we have designed the processing workflow to effectively suppress the surface Wave interference, regular interference, high energy interference, and other random noise interference. The treatment clue was from thick to thin. Firstly, the spectral analysis method was used to establish macroscopic velocity field. Then, the ray tomography method was used to enhance the accuracy of velocity analysis and to establish a more accurate velocity model. Finally, the finite difference pre-stack depth migration on method in -k domain was adopted to solve the imaging problem of subsalt and salt dome flank.
