查询词典 oxides

Conventionally the layers have been divided into A, B and C horizons. The A horizon is the upper layer, containing humus and is leached and,or eluviated of many minerals. The B horizon forms a zone of deposition and is enriched with clay minerals and iron,aluminium oxides from the A layer. The C layer is the parent material for the present soil and may be partially weathered rock, transported glacial or alluvial material or an earlier soil.

传统上可将土壤分成A、B、C三层。A层是位於最上面的一层，含有腐殖质，许多矿物质在该层中沥滤和淋溶。B层是个沉积区，富集了大量的来自A层的粘土矿物质和铁，铝氧化物。C层是现在土壤的母质层，也可能是风化的岩石、来自冰河或冲积层的物质、或早期土壤遗留下来的。
