Abstract
Field relations indicate that small-scale positive flower structures along sub-regional strike-slip faults localize ore in particular 4 m thick, bedded ore zones in Mississippi Valley-type Pb-Zn deposits of the Viburnum Trend, southeast Missouri, U.S.A. Outwardly divergent, shallow-dipping, duplex-deformed fault splays control ore and merge inwardly with sub-vertical fault strands. The characteristics of both duplex-deformed splays and ore suggest that the flower structures acted as drains for fluids being moved vertically along the strike-slip faults. This ore control differs from pipe-like conduits of transtensional dilation jogs in that duplex-deformed splays form under transpression and develop horizontal veins adjacent to strike-slip faults.
