Many gold-arsenopyrite-sulphosalt occur- rences are hosted in carbonate rocks or thin pelitic layers in volcanic rocks. This may be a function of focussing of structure in the more ductile lithologies instead of the volcanic rocks, which seem to be a preferred host for many gold deposits elsewhere.

The Grenville dike swarm is a large Proterozoic dike swarm in the Canadian provinces of Ontario and is one of the several major magmatic events in the Canadian Shield and it possibly formed million years ago along a triple junction that might have been related to a mantle plume. The maximum length of the Grenville dike swarm is km ( mi). O 18 /O 16 ratios have been obtained for rocks and minerals along a mile traverse from near the Grenville front north of Lake Nipissing to the Paleozoic contact to the east of Georgian Bay. Two types of oxygen isotopic relationships correlated with metamorphic grade and style of plutonic emplacement are observed: (A) from the Grenville fron to the Haliburton Highlands, upper amphibolite to Cited by:

Ontario Dept. Mines, Prelim. The Grenville Province: Up Close The making of the Grenville Province is the third stage in the formation of Ontario. Built from about billion to about billion years ago, it is the youngest part of the Canadian Shield. The rocks of the Grenville Province were baked, squeezed, stretched and twisted into metamoiphic.
and geochemical analysis (including whole rock and rare-earth element analyses) of these three units has been carried out. Results indicate that the batholith was formed by partial fusion of sedimentary and volcanic material; the homogeneous diatexite arose in a similar way although fusion was lessAuthor: Randall T.

The intense heat and pressure generated from the collision produced volcanic material, injected hot molten rock into the crust, and metamorphosed the sediments that had eroded from the margin of the Precambrian shield before the collision occurred. The Archean volcanic rocks and associated sedimentary rocks are intruded and deformed by two large plutons and a few smaller hypabyssal intrusions.
A petrographic and geochemical study of the Precambrian rocks exposed 1n the study area was undertaken in order to investigate the metamorphic grade and geochemical characteristics of the : Mehran.
