抄録

Geology of North Banten, West Java is characterized by the clustal movement accompanied by active volcanism during the Plio-Pleistocene epoch, and acid tuff prevails throughout the study area. Besides, andesitic/basaltic lava covers the earth surface in some parts of the area. The physiographic division shows good correspondence to the soils, which are classified into four soil units according to the FAO/Unesco World Soil Map Legend. Eutric Fluvisols are distributed on the natural levee and alluvial plains, and Eutric Gleysols are also distributed on the alluvium adjacent to the Eutric Fluvisols and valley bottoms. Orthic Acrisols develop in the river terrace region, where transported weathered tuff with variable depths often covers the surface. Dystric Nitosols are derived from tuff and lava on the plateau. Slightly to moderately weathered tuffaceous rock locally called cadas is distributed mainly in the high terrace region. Small quartz grains are most abundant at the elevations higher than 20m m. s. 1., and gradually decrease in size and number toward the alluvial plain. It is concluded that land use in this area is closely related with water, and poor drainage caused by the presence of cadas at shallow depths which often regulates the soill and vegetation.
