太田等为了研究成岩作用机理和古环境,曾追溯过贝壳在成岩过程的微量元素行为。根据矿物组成贝壳划分为霰石型和方解石型。利用现代贝壳和已知年代的贝壳化石,可以探讨并推断微量成分含量的年代变化。可是即使是同时代、同地区、同种属的贝壳,不用说是化石,就是现代风化贝壳样品中,其微量元素数据的变化范围也是相当大的,往往妨碍判断。 太田等(1979)研究了新鲜贝壳(宫城县江之岛湾养殖的Patinopecten yessoensis)不同壳体和不同部位(相同壳体中的同一发育期或不同发育期)的微
In order to study the mechanism of diagenesis and paleoenvironment, Ota et al. Trace the trace element behavior of the shell during diagenesis. According to the mineral composition of the shell is divided into aragonitic type and calcite type. Using modern seashells and shell fossils of known age, it is possible to explore and infer the chronological changes in trace element contents. However, even in contemporary, same-region and same-type seashells, not to mention fossils, that is, modern weathered shell samples, the range of variation of their trace element data is quite large and often hinders judgment. Ota et al. (1979) studied the effects of fresh shells (Patinopecten yessoensis cultured in the river bank of Miyagi Prefecture) on different shells and in different sites (the same or different developmental stages in the same shell)
