Abstract
The stratabound lead-zinc deposits of the Cercapuquio mining district are located in the high Andean region of the Department Junín, Central Peru. They are hosted by the Chaucha Formation of Middle Jurassic age. The first investigations concerning the Cercapuquio ores are related to the presence of brunckite, a very fine crystallized sphalerite (Herzenberg 1938; Zemann 1949; Sterk 1953; Levedev 1968). Geologic investigations in the surrounding areas of the Cercapuquio mine were carried out by Harrison (1956) and Mégard (1968). The genesis of the deposit has been a matter of controversy for the past 30 years. Proposed origins for the Cercapuquio ores include intrusion-associated epigenetic (Melchiori 1956; Miranda 1956; Petersen 1972) and syngenetic (Blohm 1972; Samaniego and Amstutz 1979; Samaniego 1980; Soler and Lara 1983; Soler 1987).
