求翻译：淤积带较为狭长，最大淤积厚度5～6m，而淤积厚度大于4m的宽度仅为20～30m，长度约800m，淤积厚度大于2m的宽度为50～80m，长度约1km。是什么意思？

Cholestasis with relatively long and narrow, the maximum deposition thickness of 5 ~ 6m, while the deposition thickness is greater than 4m width is only 20 ~ 30m, a length of about 800m, the deposition thickness is greater than 2m width of 50 ~ 80m, a length of about 1km.

silted up with a more narrow, and the greatest accumulations 5 to 6 m thickness, and siltation of thickness greater than 4 m width is only 20 to 30 M, length of about 800M, and siltation of thickness greater than 2 m width of 50 to 80 M, about 1km length.

Silts up the belt to be long and narrow, biggest siltation thickness 5~6m, but silts up thickness to be bigger than 4m the width only is 20~30m, length 800m, siltation thickness is bigger than 2m the width is approximately 50~80m, length approximately 1km.

Siltation is more narrow, Max thickness of silting 5~6m, and sedimentation thickness greater than 4m width of only 20~30m, length of about 800m, sediment thickness is greater than the width of the 2m for 50~80m, about 1km.
