Active Continental Margins: Contrasts Between California and New Zealand

1974
The margins of the Pacific Ocean in both California and New Zealand each contains two parallel terranes similar in age but very different in lithology, structure, and metamorphic mineral assemblages. In California, the structurally lower terrane is the Franciscan assemblage, deposited in deep marine environments and made up of rarely fossiliferous ...

Phanerozoic gold deposits in tectonically active continental margins

1991
Phanerozoic gold deposits currently account for approximately 25% of the non-communist world’s annual gold production or 53% of annual production, if the deposits of the Witwatersrand are excluded (data from Woodall, 1988). With the anticipated increase in production from newly discovered gold deposits of the southern Pacific and western US, this ...

Chapter 2 Evolution of Chert at Active and Passive Continental Margins

1983
Abstract Because paleo-oceanography is largely determined by plate movements, the patterns of continental runoff, nutrients, and depth and distance from shore affect the occurrence of marine siliceous deposits; these sediments are gradually lithified and typically end up as overthrust continental margin chert sequences.

Geodynamics and metallogeny of active continental margins of the Kyrgyz Tien Shan

2005
This paper focuses on the Late Riphean — Paleozoic stage that in the Kyrgyz Tien Shan is the most productive period in terms of ore mineralization. During the Riphean-Vendian stage, development of riftogenic structures resulted in ocean formation. Ensimatic island arcs and backarc basins rose in Cambrian — Early Ordovician time; ensialic island arcs ...
