Lowstand System Track (LST) 

In lowstand system tracks in comparison to highstand system tracks and transgressive sequences are reversed.Sea level reaching maximum drop stage, the rate of subsidence still less than the rate of sedimentation, which initially resulted in an increased sediment influx seaward because the sediments are being deposited further away from shore along margins on the platform, farther down slope, decreasing the overall sediment availability.Lowstand system tracks result in a shift of the types of sediments being deposited onto the slopes to an increase in siliclastic input of sediments. Sea level drops also shifts the type of transport further out onto the slope also decreasing the surface area onto which the sediment may be deposited "a smaller area of the shallow sea floor is in contact with the carbonate factory" resulting in retrograding shelves. Slope failure occurs frequently at times of lowstand and as a result debris-flow, grain-flow deposits primarily thickened wedges and fans develop. Additionally, the winnowing and erosion of platform corals, sediments and shallow water sediments exposed at lowstand and are deposit seaward along the slope. Toward the end of the lowstand system initial phase shifts in subsidence and seal transition to a transgressive systems track
