Based on the geology and geochemistry of gold-bearing quartz veins in the Jiudian gold deposit of Pingdu, Shandong Province, the geological and geochemical indicators of occurrence of deep-seated ore bodies in the Jiudian gold deposit have been summarized. Extent occurence of wide, intensive, varied alteration zones around the gold-bearing quartz veins and continual presence of diorite porphyrite and lamprophyry indicate the probable occurrence of deep-seated ore bodies at depth of gold lodes. As, Sb and Hg belong to the head halo elements, and their anomalies could reveal the probable occurrence of the deep-seated ore bodies below.
