Andean-type convergent continental margins (upper volcanic-sedimentary level),in mountainous setting. Some rock and ore settings in the young island arc systems (Chapter 5) that are (almost) identical to the Andean settings, like the continental crust-influenced magmatism in mature (Japan-style) island arcs, are included here. In the ancient terrains modified by dispersion an比目鱼 发表于 2025-3-29 02:16:14

Volcano-sedimentary orogens,can be best visualized if one imagines the present Indonesian Domain (Hamilton, 1979) squeezed, after collision, between the SE Asian and Australian rigid cratonic complexes. To avoid repetition, the dominant “giants”- forming ore types reviewed here are the Phanerozoic volcanic-associated massive sCHOP 发表于 2025-3-29 09:38:47
Proterozoic-style intracratonic orogens and basins: extension, sedimentation, magmatism, the oldest juvenile greenstone belts, although as an exception, in the form of the mature “pre-greenstone” association of quartz arenites or conglomerates, carbonates, possible evaporites, terrigenous detrital sediments, interspersed with at least partly subaerial basalt flows and sometimes rhyolitOrnament 发表于 2025-3-29 12:43:39
Epilogue,ent on aid. This all will take place against the reality of rapid depletion of mineral deposits some of which have been discovered centuries ago, and a great increase in complexity and cost of finding replacements as the relatively easy to find deposits have already been found.Aerate 发表于 2025-3-29 18:52:57
