According to the in door flume experiment simulations, the formation of fluxoturbidite in front of delta is studied. It is summarized that there are four kinds of fluxoturbidite in front of delta. They are the fluxoturbidite with no trigger action and one associated with seismic process, one with wave action and sandstone lens correlative with landform. The experiments suggest that trigger actions are the most important conditions to form fluxoturbidite in front of delta. Together with wave action and seismic process, the change of landform can promote forming fluxoturbidite. Also, the fluxoturbidite can be found easily in front of the delta where the delta front has been destroyed and rebuilt. In contrast, the regular and good reserved delta front is disadvantaged to form fluxoturbidite.
