Comparison of pattern-recognition techniques for classification of Silurian rocks from Lithuania based on geochemical data
pattern-recognition techniques classification Silurian rocks geochemical data
2009/12/3
There is no widely recognized chemical classification of sedimentary rocks. The geochemical classification of sedimentary rocks utilizes features that can be observed in hand specimens or in thin sect...
Large regional-scale variation in C3/C4 distribution pattern of Inner Mongolia steppe is revealed by grazer wool carbon isotope composition
regional-scale variation C3/C4 distribution pattern Inner Mongolia steppe isotope composition
2010/1/20
This work explored the spatial variation of C3/C4 distribution in the Inner Mongolia, P. R. China, steppe by geostatistical analysis of carbon isotope data of vegetation and sheep wool. Standing commu...

Several active faults affect the Central Alborz, Northern Iran. The main active faults in the region are the North Tehran and the Mosha faults and their westward continuation, the Taleghan fault. Amon...
Historical damage pattern and causes of differential damage:an approach based on combining geophysical prospecting,geological and historical-technical data
Historical damage pattern differential damage geophysical prospecting historical-technical data
2010/1/28
We describe a multidisciplinary and interdisciplinary method to analyse the causes of differential macroseismic effects caused by an earthquake in a historical town. We illustrate the method with a ca...
Analyzing the causes and spatial pattern of the European 2003 carbon flux anomaly using seven models
spatial pattern European 2003 carbon flux seven models
2010/1/15
Globally, the year 2003 is associated with one of the largest atmospheric CO2 rises on record. In the same year, Europe experienced an anomalously strong flux of CO2 from the land to the atmosphere as...
