洪积物

砂页岩、河流冲积物、洪积物、第四纪红土和花岗岩是桂东北地区农业土壤的主要成土母质。

Arenaceous shale , alluvial deposits , diluvium , the Quaternary period red soil and granite are the main soil-forming rocks in the northeast of Guangxi .

冲积、洪积物的堆积及破坏作用强度均不太大。

Alluvium , alluvial material accumulation and the damaging effects are not too much intensity .

本区全新统地层的沉积物按成因类型可分为冲积物、冲洪积物及洪积物。

Holocene strata in this area can be divided into alluvial deposits , alluvial material and diluvial genetic types of sediment .

由不同母质发育的土壤中，全钾的含量为板岩残坡积物>砂岩残坡积物>花岗岩残坡积物>洪积物>第四系冲积物；

The STK content in the soil of different parent materials was residual and slope deposit of slate > residual and slope deposit of sandstone > residual and slope deposit of granite > diluvial deposit > alluvial deposit in the Quaternary System ;

洛河组下段在盆地南部、西北和东南部边缘带，沉积体属于近缘的冲（洪）积物、泥石流和风化残积物；

The south , northwest and southwest of the downstream of Luohe formation are nearby material alluvial deposits , debris flow and weathered deposits .
