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 " .

砂质碎屑流是近年来日益受到重视的一种新的砂体成因类型，其相关理论是对“鲍玛序列”和“浊积扇”等深水沉积理论的部分否定和完善。

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 .

青藏高原东部三角形的松潘-甘孜褶皱区，全区几乎被巨厚的三叠系浊流沉积覆盖，掩盖了许多地质信息，成为国内一块神秘的土地。

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 .

结果该套浊积岩岩性同围岩类似，块状层理、平行层理、交错层理和包卷构造较发育；
