Second , the older turbidite beds need to be examined properly , to see how frequently tsunamis actually occur .
第二，旧的浊流沉积层需要更加细致正确的探测，以确定海啸发生的确切频率。
That five layers of turbidite may have formed in this time gives a rough sense of how frequently tsunamis might happen .
这段时间形成的五层浊流沉积层可以大概的知道海啸发生的频率。
Sandy debris flow is a new sandy type and attracts more and more attention in recent years . Its relative theory is partial negation and improvement of deep water sediments concepts like the " bouma sequence " and " turbidite fan " .
The triangular songpan-ganzi foldcd area in eastern qinghai-tibetan plateau is almost covered with very thick triassic turbidite deposit and lots of geologic information may be enveloped , so it becomes a mysterious land in china .
Results it shows that lithology of turbidite is similar with that of wallrocks . Blocky bedding , parallel bedding , cross-bedding and convolute structure are better developed in this area .
