| Complex crystal growth zonation can be subsampled to provide a high resolution record of elemental and isotopic chemistries during the evolution of diagenetic fluids. This figure illustrates zonation visible only under cathodoluminesce petrography. This visible zonation can be further subsampled to allow the analysis of intra-zonal variations. Example |

| Accretionary Growth Structure in Clams Shell. The growth
banding present with in molluscan shells allows for reconstruction of seasonal
variations in environmental conditions present during the life of this
organism. By using the visible growth banding it is possible to subsample
within annual banding to document the seasonal scale variability.
Examples: 1. Paleogene
bivalves from Antarctica;
2. Cretaceous and Paleogene freshwater bivalves;
3. Recent freshwater bivalves; 4. Otolith research (earbones of fishes) |
