Potential for Porphyry Copper Deposits in Northern Tōhoku (or the Exploration Potential for Base and Precious Metal Deposits in Japan ) Antonio Arribas. hemipelagic, and pelagic sedimentary rocks accompanied by subsidiary limestones, cherts, and basalts (Isozaki, ).Cited by: 1. Sedex deposits are major sources of zinc and lead, and can be considered as a subgroup of massive sulfide deposits associated with sedimentary rocks. Both the sediment and volcanogenically hosted massive sulfide deposits are characterized by lenses or sheets of ore that comprise at least 60% sulfide, hence the origin of the name.
Invited papers were presented in four ses- sions: (1) Copper deposits in mafic and ultramafic complexes, (2) Porphyry copper deposits, (3) Copper deposits of volcanic-hydro- thermal association, and (4) Sediment-hosted copper deposits. The sessions were chaired by A. D. Genkin, A. J. Naldrett, J. D. Ridge and G. I. Gorbunov; V This book is an outgrowth of my interest in the chemistry of sedimentary rocks. In teaching geochemistry, I realized that the best examples for many chemical processes are drawn from the study of ore deposits.
The book will be dominantly read by students and teachers, but could also be useful for professional geologists wanting a modern overview of a wide range of ore deposits and ore-forming processes.

Volcanogenic massive sulphide deposits are a major source of copper, zinc, lead, silver and gold. These deposits have been found actively forming at a temperature of degrees Celsius. Hydrothermal vents on spreading ocean bottom ridges, such as those found in the eastern Pacific Ocean are actively precipitating metal sulphides.

Volcanogenic massive sulfide ore deposits, also known as VMS ore deposits, are a type of metal sulfide ore deposit, mainly copper-zinc which are associated with and created by volcanic-associated hydrothermal events in submarine environments.
These deposits are also sometimes called volcanic-hosted massive sulfide (VHMS) deposits. The density generally is kg/m 3. Mining and Mineral Processing. Metal deposits are mined in a variety of different ways depending on their depth, shape, size, and grade.
Relatively large deposits that are quite close to the surface and somewhat regular in shape are mined using open-pit mine methods (Figure ). Creating a giant hole in the ground is generally cheaper than making an underground mine, but it is also less Author: Steven Earle. Calc-alkaline plutonic rocks occur within a few tens of kilometers of most of the gold deposits in Alaska and generally were emplaced coevally with hydrothermal activity.
Ore-bearing veins are composed predominantly of quartz and show brittle and/or ductile features depending on the district.

Not all metal deposits have igneous origins- sedimentary deposits can also be a valuable source of many metals, including copper.
While sedimentary copper deposits share the feature of a. Most sediment-hosted copper deposits are in terranes principally composed of sedimentary rocks.
RF: Alluvial clastic redbeds and rift-related volcanic rocks; may contain evaporites in subsurface. RB: Alluvial clastic redbeds with or without evaporites. RV: Precambrian alluvial and shallow marine sedimentary rocks of low metamorphic Size: KB. Copper-bearing minerals can be found in deposits hosted in a wide variety of rocks.
Most of the world's copper production comes from "porphyry" deposits, which by definition is igneous, but many copper deposits are also sedimentary (eg red beds), metamorphic (eg skarns), and volcanic (eg volcanogenic massive sulfides).
Sediment-hosted copper deposits are formed by fluid mixing in permeable sedimentary and (more rarely) volcanic rocks. Two fluids are involved: an oxidized brine carrying copper as a chloride complex, and a reduced fluid, commonly formed in the presence of anaerobic sulfate-reducing by: Mineral deposit - Mineral deposit - Hydrothermal solution: Hydrothermal mineral deposits are those in which hot water serves as a concentrating, transporting, and depositing agent.
They are the most numerous of all classes of deposit. Hydrothermal deposits are never formed from pure water, because pure water is a poor solvent of most ore minerals. Mineral Deposits of Finland is the only up-to-date and inclusive reference available that fully captures the scope of Finland’s mineral deposits and their economic potential.
Finland hosts Europe’s most mature rocks and large cratonic blocks, analogous to western Australia and Southern Africa, which are the most mineralized terrains on Earth.
Ore deposits directly related to mafic and ultramafic magmatism include nickel sulfide deposits that are locally enriched in copper, cobalt, platinum group elements and gold, a diverse range in.

Formation of Sedimentary Rock-Hosted Stratiform Copper Deposits through Earth History Article in Economic Geology (3) June with 1, Reads How we measure 'reads'. Sedimentary rocks are formed from the erosion of older instrusive, volcanic rocks or even other sedmentary rocks. They may also be formed through biologic processes, such as coral reef formation.
Mineral deposits may form in sedimentary rocks through the erosion of ore-bearing rocks or through the mobilization of ore-bearing fluids through. out of 5 stars Sedimentary Deposits And Their Origins. Reviewed in the United States on Ma I acquired this book, Principles of Sedimentary Deposits: Stratigraphy and Sedimentology (Hardcover Edition) by G.
Friedman.4/5(1). Sedimentary Deposits mineral deposits formed during the accumulation of sediment on the bottom of rivers and other bodies of water.
According to their place of formation they are divided into river, swamp, lake, sea, and ocean deposits. Among ocean deposits a distinction is made between platform and geo-synclinal deposits.

A brief summary of the data obtained by numerous investigators on the sulfur isotope composition from stratiform copper-zinc and lead-zinc deposits from the USSR occurring in sedimentary and volcanogenic-sedimentary rocks is presented in this paper.
The problems of the genesis and the source of metals and sulfur are still open to by: 2. Volcanogenic Massive Sulphide Deposits.
Much of the copper, zinc, lead, silver, and gold mined in Canada is mined from volcanic-hosted massive sulphide (VHMS) deposits associated with submarine volcanism (VMS deposits). Examples are the deposits at Kidd Creek, Ontario, Flin Flon on the Manitoba-Saskatchewan border, Britannia on Howe Sound, and Author: Steven Earle.Sedimentary rock - Sedimentary rock - Organic-rich sedimentary deposits: Coal, oil shale, and petroleum are not sedimentary rocks per se; they represent accumulations of undecayed organic tissue that can either make up the bulk of the material (e.g., coal), or be disseminated in the pores within mudrocks, sandstones, and carbonates (e.g., oil shale and petroleum).
