Minerals associated with large sulphide bodies of the Sudbury area
Sudbury district, where copper sulphides, chiefly chalcopyrite, occur in association with nickel sulphides in the well known deposits of nickeliferous pyrrhotite of that region. North shore of Lake Huron, comprising the area westward from the Sudbury district to Lake Superior, and extending northward for at least 40 miles.

Ore treated on site in stamp mill and cyanide plant. ;. 1/There is- one producing mine«m the area; four past-producers, and numerous sulphide occurrences. Consequently, the area has been subjected to intensive exploration for many years. The sulphide ore bodies, and most of the sulphide occurrences, are located at the base of the nickel irruptive and in the Worthmgton offset. There.
Nickel Sulfide Ores and Impact Melts: Origin of the Sudbury Igneous Complex presents a current state of understanding on the geology and ore deposits of the Sudbury Igneous Complex in Ontario, Canada. As the first complete reference on the subject, this book explores the linkage between the processes of meteorite impact, melt sheet formation, differentiation, sulfide . Violarite, a violet-grey sulphide of iron and nickel, ideal formula FeNi 2 S 4 ( weight percent Ni), is a moderately uncommon cubic ore mineral, found in some nickel deposits. This sample is from the Vermilion mine west of Sudbury, Ontario*. Seen in photomicrograph with yellow millerite (NiS). The violarite has a characteristic grey colour with a violet tint, and displays cubic .

The Sudbury Basin / ˈ s ʌ d b ə r i /, also known as Sudbury Structure or the Sudbury Nickel Irruptive, is a major geological structure in Ontario, is the third-largest known impact crater or astrobleme on Earth, as well as one of the oldest.
The crater formed billion years ago in the Paleoproterozoic : Ma, Paleoproterozoic. Ore deposits that are associated with mafic to ultramafic igneous rocks can generally be divided into those where the metals of interest are hosted in oxide minerals and those where the metals of interest are held as sulfides or are strongly associated with sulfides (e.g., PGE alloys, arsenides, bismuthinides).
The oxide ore bodies include stratiform, podiform, and breccia-related. Sulphide is a settlement in the municipality of Tweed, Hastings County, Ontario, Canada, about kilometres ( mi) west of the community of Hungerford and 8 kilometres (5 mi) northeast of the village of Tweed.

Geology and mineral deposits, Sudbury area, Ontario (Guide book for field trip)Author: H. F Zurbrigg. Nickel Sulfide Ores and Impact Melts: Origin of the Sudbury Igneous Complex presents a current state of understanding on the geology and ore deposits of the Sudbury Igneous Complex in Ontario, Canada.
As the first complete reference on the subject, this book explores the linkage between the processes of meteorite impact, melt sheet formation, differentiation, sulfide 4/5(2). A more positive role may have been played by sulphide minerals in the emergence of life on Earth; although speculative, such theories have been developed following the discoveries of ocean-floor hydrothermal systems generating large volumes of sulphide minerals and associated with novel life forms and ecosystems.

Legault, B. Lafrance, and D.E. Ames. The most accepted theory is that a meteorite slammed into the area billion years ago, shaping a bowl 37 miles long, 17 miles wide and 10 miles deep. In the aftermath, minerals bubbled to surface around the rim, creating one of the. The Yellowknife gold camp on Great Slave Lake is the principal producing area.
“Most of the gold deposits are auriferous quartz veins or quartz bodies associated with a little schist or other altered wall rock, and in most instances contain not more than about 1 percent of such minerals as pyrite, galena, sphalerite, chalcopyrite, and.
The Bushveld Igneous Complex (BIC) is the largest layered igneous intrusion within the Earth's crust. It has been tilted and eroded forming the outcrops around what appears to be the edge of a great geological basin: the Transvaal is approximately 2 billion years old and is divided into four different limbs: the northern, southern, eastern, and western limbs.

Gold and copper are found in sulfide minerals disseminated throughout the large volumes of intrusive rock (strictly speaking, this ore is associated with volcanic systems, usually not the volcanoes themselves).
This requires large amounts of rock to be mined, often in open pits.Strathcona Mine, Levack Township, Sudbury District, Ontario, Canada: A nickel mine located in Levack Township.
