| Zusammenfassung |
| We analyze electron microscope X-ray spectroscopy data of recent supratidal
marine sediments. Statistical measures are used to characterize the
distribution of silicon and calcium in different layers of the sediments. We
also use cluster analysis and symbolic dynamics to filter measurement noise
and to classify different density regions. This allows to calculate
characteristic patch sizes which reflect the sizes of individual clastic
grains and the corresponding pore sizes. Silicon indicates the independent
processes in the sedimentation history of certain grains. Calcium is
capable to monitor intrinsic early diagenetic processes of
biogeochemical calcium mineralization of primary organic matter as
documented in more organized distributions with higher clustering. |
