近来的大气层研究表明,大量的土壤物质正被搬运出亚洲,横越过太平洋北部的广袤地区。在太平洋中北部,大气微粒中的矿物质推测的沉降率为6—12×10~(12)克/年,实测的沉降率为20×10~(12)克/年,这就可以解释这一地区深海沉积物中大部分碎屑为非生物组份的原因。在该地区,由沉积学家们早先已估算到,占75—95%的沉积物来源于大气尘埃的降落。如果能说明现代大气微粒中的土壤物质成份,与在过去几千年间沉积的下伏沉积层的矿物成 Recent atmospheric studies have shown that large amounts of soil matter are being transported out of Asia across the vast areas of the northern Pacific. In the central and northern parts of the Pacific Ocean, the estimated subsidence of minerals in atmospheric particulates is 6-12 × 10-12 grams / year and the measured sedimentation rate is 20 × 10-12 grams / year, which explains why The majority of debris in deep-sea sediments in a region is responsible for abiotic components. In the area, sedimentsologists have previously estimated that 75-95% of the sediment comes from the fall of atmospheric dust. If we can explain the composition of soil material in modern atmospheric particles, with the mineral deposits of the underlying sediments deposited over the past several thousand years
