Abstract

These maps (Maps A and B) show the distribution and abundance of maganese in the nonmagnetic and magnetic fractions of heavy-mineral concentrates from stream sediments collected in the Silver City 1o x 2o quadrangle, New Mexico and Arizona. Geochemical maps showing the distribution and abundance of 10 other selected key elements and the mineral fluorite in the Silver City quadrangle are also part of this folio (Watts and Hassemer, 1980; Watts and others 1986a-i). These maps contribute to the assessment of mineral resources within Silver City 1o x 2o quadrangle by (1) showing regional patterns of elements enriched in heavy-mineral concentrates, thereby providing clues to regional patterns of mineralization; (2) showing new areas containing enriched metals, not previously known from mining activity; and (3) providing supportive data to the interpretive and summary maps (Watts and Hassmer, 1986) and the mineral resource assessment (Richter and others, 1983). Background information that pertains to published components of the Silver City Folio is also available (Richter and others, in press).
