Abstract :

Halakabad mineralized area is located about 30 km south of Sabzevar. Basalt, andesite, hornblende andesite and hornblende dacite are the oldest volcanic rocks outcropping in the study area. monzodiorite, Quartz diorite, quartz monzodiorite, quartz monzonite, and hornblende quartz monzodiorite intruded the volcanic rocks. Principal component analysis is one of the methods that can help reveal simpler patterns within a complex set of variables. Principal component analysis in Halakabad is showing most variable can be categorized in five components. Results for geochemical data show first component has positive loading for Cu, Zn, Co, V and also Li, Th, Cs, Sr and negative loading for Pb, Ba, Rb and Nb. Second component has negative loading for Rb, Sr, Th, Ba and positive loading for other elements. Association of Zn with Pb and F demonstrates another mineral paragenesis in the area. Third component has positive loadings for Ni, Co, Cr and Zn. The chemical elements with positive loadings of the second component are associated with alteration and subvolcanic rocks. Principal component analysis in Halakabad area demonstrated at least two type of Cu and Zn mineralization.
