In the paralic zone .there are ample oil and gas resources, moreover, it is the important mothball area and reliver of oil and gas industry to increase reserves and enhance output.
In the framework of Geoacoustics interface wave theory,a time domain finite difference model for the propagation of interface wave in shallow sea has been developed.
Its original rock is sedimented in the environment of active epicontinent-seaboard with basic volcanism, and become khondalite series through the Archean regional high-amphibolite facies metamorphism.
One hundred million years later, the warm, shallow seas were packed with tiny plants and animals — essentially, hors d'oeuvres for a plethora of bigger creatures like trilobites, conodonts, brachiopods, and corals.
At the time of the impact, the impact site itself was under a shallow sea of a couple hundred feet deep and so very naturally, one of the immediate effects of the impact itself was to launch an enormous Tsunami.
