Veins and pegmatite are suitable carriers for the mineralization of several elements such as Au(gold), Silver(Ag), Cu( copper) etc. in this paper we will discuss the REE and Gold mineralization in the korukonda area nearby to Rajahmundry, Andhra Pradesh. Here pegmatite was the rich source of REE, Graphite and quartz vein intruded within the Migmatite gneiss could be a potential source of Au(Gold). The values of Rare Earth Elements (REE) from Lanthanum (La) to Lutetium (Lu) are exclusively higher concentration in the eastern and Northeastern parts of the area, The value of LREE Ranges from143.25 ppm to 2042.75 ppm, and HREE ranges from 9.09 to 27.37 ppm. the maximum value of Au(gold) observed is around 47 ppb in stream sediments which indicates moderate enrichment of Au (Gold) in the study area .
