Precise Temporal Correlation of Holocene Mollusk Shells Using Sclerochronology
Abstract Annual growth bands of mollusk shells record several types of paleoenvironmental information, including geochemical proxies for water properties and morphological characteristics of growth and mortality. Sclerochronology, the marine counterpart of dendrochronology, offers a way to link indi...
