Fig. 3From: The effects of meteoric diagenesis on the geochemical composition and microstructure of Pliocene fossil Terebratalia coreanica and Laqueus rubellus brachiopod shells from northeastern JapanSchematic illustration of the sampling procedure for geochemical analyses of the modern and fossil shells. The red and blue arrows indicate sampling intervals of 1 and 2 mm, respectively. Shells were cut along the maximum growth line and then along a line perpendicular to the maximum growth axis. Thin sections along the maximum growth axis were examined in CL images. SEM observations were carried out on the cross-section along the line perpendicular to the maximum growth axis. Individual shells were divided into three intervals (intervals 1–3) based on the shell morphologyBack to article page
