MODELACIÓN DE ELEMENTOS TRAZA EN EL HORIZONTE A DE SUELOS, PLANCHA 170 (VÉLEZ, DEPARTAMENTOS DE SANTANDER Y BOYACÁ) MODELING ELEMENT TRACE IN THE HORIZON TO OF SOILS, PLATE 170 (VÉLEZ, DEPARTMENTS OF SANTANDER AND BOYACÁ)
The spatial distribution of many metals that can be potentially dangerous or of certain toxicity (EPP) in soils of the area of Colombian cartography (Plancha 170 Velez) was analyzed in this study. It was used a sampling methodology of low density and it was taken soil samples at the A horizon, analysed for 48 elements using (ICP-MS) and neutronic activation. The first three components represent 88% of the total variability of the data, showing associations as: CP1= V-Sb-Mo-Cr-Ni-Zn-Cu-U, with a 73% of the variance and with the major numbers of elements that can be relational to lithologies as lodolites and sandstone maybe some rich in uranium and others metals. The second principal component CP2 = Ni-Zn-Cu could be with relationship to sulphur bearing ore deposits, and finally CP3 = Mo-V-Ni-Sb-Cr indicates a natural association to lithologies as shales that act as metal scavenger. For the first principal component (CP1) it was generated a krigging map applying geostatistic techniques.
