Besides deltas and placer deposits, stream deposits can also lead to the formation of alluvial fans and floodplains. Alluvial fans occur where a stream flows out of a narrow canyon into a wider area, depositing sediment in a fan-shaped pattern. Floodplains are flat areas adjacent to rivers that become covered with sediment during flood events, enriching the soil for agriculture. These features contribute to the shaping of landscapes and ecosystems.
A delta is a result of sediment deposition by a river as it flows into a larger body of water, such as a lake or ocean. The sediment builds up over time, creating landforms that are shaped like a triangle or fan. Deltas are important for supporting diverse ecosystems and providing natural protection against flooding and erosion.
The origin of the rare earth deposits in the Northern Quebec is as a result of the volcanic activity within the area.
The rocks, sand, and silt eroded by a river is called the "load."
Wind erosion and deposition may form sand dunes and loess deposits.
When water loses its ability to hold sediment due to a decrease in velocity or capacity, it deposits the sediments it was carrying. This process is called sedimentation, and it can result in the formation of sedimentary layers over time.
deltas and placer deposits
Erosion removed material from the mountains and deposits it in deltas to create good soil
alluvial deposits that can form river deltas.
A river delta is the landform occurring at the river mouth, where the river meets the sea. It is largely a result of the silt brought down by the river system. The river spreads out in a fan shape into many channels called distributaries, which form outlets and islands. Notable Deltas are the Nile, Amazon and the Mississippi. Deltas are produced when rivers bring down sediment and deposits from the catchment area. These deposits form a chemical reaction with the seawater and different soils of the coast, coagulating into a clay which settles on the river bed. Deltas are only formed where there is high velocity of the river dumping into an almost tideless sea. The sediment is thus deposited over a wide area.

The California Gold Rush of 1848 was primarily driven by the discovery of placer gold deposits, which are concentrations of gold particles found in riverbeds and alluvial deposits. These deposits formed as a result of erosion from gold-bearing quartz veins in the nearby Sierra Nevada mountains. The ease of access to this gold in river sediments attracted thousands of prospectors and miners, leading to a massive influx of people to California in search of fortune.

I'm afraid you've misunderstood sediment, and you can't concatenate two such different structures as you have. Sediment is deposited fragments of material sized from silt up to cobbles or boulders, resulting from weathering and erosion of any rock. Deltas are estuarine deposits of sediment transported suspended in the river, from erosion up-stream. Caves, or most of them anyway, do not result from erosion of sediments, but from the erosion by chemical weathering (dissolution) of sedimentary rock - specifically limestone - and the material is carried away in solution not suspension.

When rocks and sediments are moved, erosion occurs, resulting in the formation of landforms such as hills, valleys, canyons, and deltas. Sediments can also accumulate to form new landforms like beaches and sand dunes.
