Sarta Barbara盆地的沉积物积累相对较快：根据纹管分析，约为3至4 mm yr/sup-1/。这些矿床是研究核年代学技术在自然条件下适用性的理想场所。通过对圣巴巴拉最近沉积层中几种放射性核素、人造/sup 55/Fe和天然/sup 210/Pb和Th同位素的深度分布的研究，可以评价Fe、Pb、和Th在沿海沃茨中的作用，并建立了有用的/sup 55/ Fe和/sup 210/分别用于近十年和半个世纪以来沉积的海岸或近岸沉积物的铅测年。（auth）
Sedimerts accumulate in the Sarta Barbara Basin relatively rapidly: about 3 to 4 mm yr/sup -1/ based on the analysis of varves. These deposits are ideal for studying the applicability of nuclear geochronological techniques in a natural situation. Studies of the depth distribution of several radionuclides, manmade /sup 55/Fe and naturally occurring /sup 210/Pb and Th isotopes, in recent Santa Barbara sediment layers permit an evaluation of the geochemical behavior of Fe, Pb, and Th in coastal waters and have established the usefulness of /sup 55/ Fe and /sup 210/Pb for dating coastal or near coastal sediments deposited during the last decade and half-century respectively.
