Recent simulations of diffusion limited cluster-cluster aggregation (DLCA) have shown systematic inhomogeneities in the shape and orientation of clusters formed when a sedimentary force is applied. Using custom simulation and visualisation techniques and programs we have carried out a microscopic study of these sedimentary inhomogeneities and have mapped out the model parameter space. We find v...

In this paper, we investigate the penetration capabilities of microwaves, particularly at L-band, for the mapping of subsurface heterogeneities such as lithology variations, moisture or sedimentary structures. The experiment site, the Pyla Dune, is a bare sandy area allowing high signal penetration and presenting large subsurface structures (paleosoils) at varying depths. Several radar data set...

The Malmyzh ore cluster, which was revealed in 1970–1976, is located the central part of Khabarovsk territory, on right bank Amur River. deposits are timed to Late Cretaceous intrusions that break through sedimentary formations Early Cretaceous. Mineralization controlled by intrusive dome structures.

Seagrasses can incorporate substantial amounts of 34S-depleted sulfide into their tissues wit...
