iii ABSTRACT Middle Ordovician carbonates in the Lake Simcoe area, south-central Ontario were examined to determine if: (1) The δ18O values of early-stage calcite cement in hardgrounds are useful proxies for Ordovician seawater δ18O values; (2) a regional hydrothermal event affected middle Ordovician strata in the Lake Simcoe area.

The wood it produced was used mainly for fence pickets, laths for plastering, and wooden boxes for packaging vegetables, fruit, and fish. Large three-mast schooners, including some that had been built right at the mill, shipped the lumber south of Georgian Bay to Lake Huron ports such as Sarnia and Goderich. But soon it all ended.

The Grenville province (Fig ), is the youngest component of the Canadian Shield, it was formed during the – Ma Grenville orogeny and exposes the doubly thickened crust at middle to lower levels providing a unique opportunity to study a Himalayan-scale orogen at depth.

The Grenville orogeny was a long-lived Mesoproterozoic mountain-building event associated with the assembly of the supercontinent record is a prominent orogenic belt which spans a significant portion of the North American continent, from Labrador to Mexico, as well as to Scotland.
Grenville orogenic crust of mid-late Mesoproterozoic age (c. – Ma) is found worldwide, but. The Wanapitei Complex (6 km× km), lying km southeast of the Grenville Front, consists of a northwestern zone of gabbro and folded injection breccia and a southeastern layer of intensely folded hornblendeplagioclase gneiss.
Disseminated Ni-Cu sulphides are unevenly distributed in a zone between the injection breccia and the folded gneiss. Rocks of the mineralized zone occur in Cited by: 3.
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. The Grenville rocks themselves have quite a story. 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 Ontario Geological Survey has issued a Guidebook on the Rocks of the Grenville Province near Renfrew, Ontario (OFR); and a Report on the Chenaux gabbro intrusion near Renfrew (OFR) I don’t often venture up the Ottawa valley to the Town of Renfrew or to Renfrew County, as there is so much to explore in Lanark County, southern Author: Christopher Brett.
The Mulock granite batholith is exposed over km 2 in the northern part of the Grenville Province, 25 km north of North Bay, Ontario. The batholith has a U Pb zircon emplacement age of +4/-3 Ma. Two regional tectonic events affected the batholith: (1) moderate-grade regional metamorphism; and (2) shearing and mylonitization related to the Grenville Front Tectonic Zone which slices Cited by: A series of late Tertiary rhyolitic and dacitic flows, domes, and minor pyroclastic rocks form an elongate volanic mass along the northwestern Utah-northeastern Nevada border.

The majority of the volcanic rocks in the Beardmore-Geraldton Belt are interpreted to represent fragments of oceanic crust trapped at a consuming plate margin. Subsequent post accretionary intrusion of gabbroic rocks (sensu lato) with calc-alkaline affinity is considered to result in the apparent hybrid tectonic setting recognized for the BGB.
) banged into that craton. The North American plate was enlarged by the rocks that, today, form the oldest part of Virginia.
(In the cereal analogy, some new-arriving Cheerios joined the North American craton.) When those chunks of rock drifted together, the heat and pressure melted various rocks as the Grenville Mountains were uplifted.

Geologists have corrected a mix-up that made an ancient geological structure in the central U.S. seem hundreds of miles shorter than it really. By: Kristina Anderson, assistant curator Today, planet Earth is believed to be around billion years old. The geological time scale, which is in continual reconstruction, divides Earth history into broad spans of time.
Many boundaries are marked by a biological event, such as the appearance of a new species. The Precambrian was originally defined as the time before life. The Grenville Sub-Province includes that part of the Canadian Pre-cambrian lying in eastern Ontario, extending north and east into Quebec.

Some or all of the minerals in the original rock may chemically react with one another or with fluids circulating in the rocks to form new minerals. Some of the original minerals may remain the same mineral, but grow larger and/or change shape.
