(1997)	10.1016/S0012-821X(97)00041-1	EPSL148_287	Lower Silurian was onset of mineralization, continuing mineralization until Upper Devonian. W/ 2 main episodes of mineralization "one in early Silurian time and another ending in early Carboniferous time. This suggests, in turn, that mercury was deposited both by the alkali basalt volcanic rocks and by later Hercynian metamorphism or magmatism. The early event remains poorly constrained, although it probably took place shortly after deposition of the ore-hosting Lower Silurian Criadero quartzite"
