Identification Outcropping Copper Mineralization in the Township of San Jose de Oriente, La Paz, Cesar

Abstract

Southwest of the township San Jose de Oriente, in the area known as La Lagunita, La Paz municipality, Cesar department, exploratory studies of surface geology were performed on La Quinta formation, allowing identify outcrops of mineralized zones and litho stratigraphic units in the area. Four samples were taken in the contact zone, host, rock and mineral, by Rock Chip method; one of which was sent to qualitative analysis by studying X-ray diffraction and the other was sent to quantitative analysis by atomic absorption in the Industrial University of Santander laboratories, to determine associated minerals and the copper percentage present in the manifestation. From the results obtained with the X-ray diffraction analysis, the constituent minerals or rocks were identified such as: Quartz (SiO2 ), Albite Na(AlSi3 O8 ), Clinochlore (Mg, Fe, Al)6 ((OH)8 (AL, Si)4 O10), Hematite (Fe2 O3 ), Orthoclase (KAlSi3 O8 ), Illite (K,H3 O)(Al,Mg,Fe)2 (Si,Al)4 O10[(OH)2 ,(H2 O)], Glagolevite NaMg6 [Si3 AlO10](OH,O)8 H2 O, Malachite (CuOH)2 CO3 and by the atomic absorption results was achieved verify the high concentration of copper-1,45 % Cu
