Numerous modern sedimentary basins contain geological features similar to those associated with the giant (150 Mt) Sullivan Pb-Zn-Ag deposit (British Columbia) in the Mesoproterozoic Belt-Purcell Basin. Important features at Sullivan include a large synsedimentary mud volcano that hosts the stratabound and partly stratiform sulfide ores, an underlying vent complex of altered and mineralized rocks, and mafic sills in the shallow to deep footwall. High-resolution 3D seismic profiles of the North Sea region and the South China Sea, as well as other late Mesozoic to Cenozoic basins such as the Irish Rockall Basin, suggest the presence of mafic sill complexes with overlying fluid-escape pipes, mud volcanoes, and hydrothermal vent complexes of diverse size and shape. Although fluid-escape pipes and related discordant features in modern sedimentary basins are widely accepted as being linked to hydrocarbon generation and resources, potential for metal concentrations in these basins should also be tested. Evaluating this possibility can be done using high-resolution seismic surveys followed by deep drilling.

现代沉积盆地中 Sullivan 型铅锌银矿床的潜力

许多现代沉积盆地的地质特征与中元古代带-珀塞尔盆地中巨大的（150 公吨）Sullivan Pb-Zn-Ag 矿床（不列颠哥伦比亚省）的地质特征相似。Sullivan 的重要特征包括一个大型同沉积泥火山，其中包含层状和部分层状硫化物矿石，一个由蚀变和矿化岩石组成的下伏喷口复合体，以及浅到深下盘中的镁铁质基岩。北海地区和南海以及其他晚中生代至新生代盆地（如爱尔兰罗卡尔盆地）的高分辨率 3D 地震剖面表明存在具有上覆流体逃逸管、泥火山、和不同大小和形状的热液喷口复合体。尽管现代沉积盆地中的流体逃逸管和相关的不协调特征被广泛接受为与碳氢化合物的生成和资源有关，但也应测试这些盆地中金属浓度的潜力。可以使用高分辨率地震勘测然后进行深钻来评估这种可能性。
