Abstract

Abstract

It is urgent for us to undertake deep prospecting in Xiaoqinling quartz vein type gold ore field, an important gold enrichment area in China where many famous mines are becoming crisis mines gradually. Trend surface analysis of ore veins can intuitively reflect regional and local trends of geological variables, which can be used for studying ore-controlling structure features and guiding deep prospecting. By the trend surface analysis on ore body thickness, Au and Pb grades of three typical ore veins, this paper presents the following mineralization enrichment rules and fault ore-controlling features found in the study. The main ore veins strike EW and are pitched to southwest. Ore-controlling fault thrusts from SW to NE obliquely with leftward contortion. Multistage mineralization is featured with three stages in which veins formed primarily in the first stage, Au mineralized strongly in the second stage and Au-Pb mineralization superposed in the third stage. Controlled jointly by orebody plunging direction and fault wavelike occurrence, the intersectional parts of two structure lines distributed proximal parallel and equidistantly are advantageous mineralization enrichment areas, which are the promising for future deep prospecting in these ore veins.
