A Spectrum of Sea-floor Sulphides,assified as proximal. Others may have been deposited by sea water far from the centres, and they are called distal (.). There therefore exists a spectrum of deposit-types, some more associated with volcanic rocks, others more with sedimentary formations.作者: 嬉耍 時間: 2025-3-22 04:22
Field Evaporation and Related Topics,opose an average or standard ocean structure (Worzel, 1974). This structure varies quite dramatically from that of the continental areas (.). The sea water is an important layer of the oceanic crust. It contains trace elements and obviously has an important role in the formation of the layer of sediments and metal concentrations on the sea floor.作者: 有發(fā)明天才 時間: 2025-3-22 07:42 作者: Nonconformist 時間: 2025-3-22 09:20

They occur in large epicontinental basins close to Archaean cratons and are assumed to have a volcanic-exhalative origin, though more distal from the eruptive centres than the typical Archaean deposits.

A Spectrum of Sea-floor Sulphides,ated rock assemblage allows their tectonic setting of formation to be deduced fairly accurately. It is generally accepted that they formed at or close to the ocean floor by volcanic-exhalative processes. Summaries of the deposits are given by Hutchinson (1973, 1980) and Sawkins (1976).

Mineralization in intracratonic basins,ndwanaland. Sea-floor spreading along the major rift system led to the progressive westwards drift of the Americas. The Benue Trough of Nigeria—Cameroons, however, failed to achieve complete separation and ended up as a failed arm or aulacogen (.).

Intrusive bodies emplaced in stable cratonic terrain,the intrusions; they may be Precambrian or Phanerozoic. The only common feature is that the terrain into which they have been intruded is characterized by long geological stability. Such intrusions are absent from oceanic areas and restricted to continental shield areas.作者: 沒血色 時間: 2025-3-26 09:02

Introduction,What is economic geology? It may be defined as the study of geological bodies and materials that may be useful to mankind. The materials included are fuels, metallic and non-metallic minerals, rocks and water. This book will exclude considerations of water and building materials, and will concentrate on ores and fuels.作者: 褪色 時間: 2025-3-27 01:45
Batholith-associated mineralization,Batholiths are characteristic features of cordilleran volcano—plutonic arcs at destructive plate junctures or collision belts paralleling orogenic suture zones. Important mineralization is associated with the granitoid phases of the batholiths, which vary considerably in character and composition with tectonic setting.作者: Dendritic-Cells 時間: 2025-3-27 08:13
