the kaolinitic clays have been exploited for more than a hundred years, in the western part of the charentes basin, france, and belong to a paleo-deltaic network. the recent deposits are relatively richer in alumina in comparison with the older ones. the genesis of the kaolin deposits of the charentes basin follows simple geological rules, but their detailed geometry has a great complexity, rei...

The management of soil organic matter (SOM) is fundamental in agriculture for conservation and crop yields. However, addition the being dynamics, it heterogeneous, therefore, understanding spatial variability SOM essential. main objective this study was to evaluate a cassava cultivation under different management, seeking classify its dependence by geostatistics. A filed experiment conducted ou...

Geostatistics has become a powerful method for investigating complex spatial variations of prehistoric settlements in floodplains and other geomorphological settings. A geoarchaeological drilling program that covers most the Sha-Ying River Basin provides rare opportunity with unusually detailed environmental data to contest develop geostatistics method, which proves be essential, combination ar...

Spatially distributed estimates of ecological variables are generally required for use in geographic information systems (GIS) and models when dealing with many environmental phenomena [2]. In particular, the quality of GIS products depends often on local properties that vary in space. In this context, increased interest has been demonstrated to geostatistics, or spatial statistics, as an analy...
