Dikes

Permanent dikes were erected in eight towns south of Winnipeg, and clay dikes and diversion dams were built in the Winnipeg area.

Additionally, the funding stream for disaster-risk reduction and climate adaptation will support structural projects, such as dikes and pump stations, with funding of as much as $5 million, increased from $2 million.

Gold mineralization is hosted within a meta-sedimentary sequence dominated by banded (graphitic) quartzite and interbedded pelitic biotite schist that is cross-cut by numerous felsic to intermediate dikes and sills.

Late-stage aplite, quartz feldspar porphyry and mafic dikes also occur with the mineralized zones and in outcrop.

The dikes are typically composed of Spodumene (lithium aluminium silicate in the pyroxene family) as well as accessory minerals including quartz, feldspars and micas.

Complicating the issue are centuries of alterations, like dikes and ditches, that prevent water from flowing through the marsh as it should.

Marcos explained that the country needs to adapt to the rising sea level due to climate change, and that building higher dikes is not enough.

Brazilian miner Vale offered updates on ongoing emergency protocols related to two of its dikes.

For hundreds of years, Nova Scotia’s coast has been protected by dikes first built by the Acadians.

For the Kerguelen Plateau, the mantle plume provided the necessary heat to melt the rocks, as tectonic movements along the spreading mid-ocean ridge kept the dikes open, which successively acted as a 'magma conveyor belt' for more than 30 million years.

The Provo Delta Restoration project will remove dikes and construct a system of channels and ponds that will serve as a safe haven for larval suckers.

This system of levees, dikes and walls usually held up during the last century but is now being over-topped more frequently by heavier storms that scientists link to global warming.

When Dièreville arrived, the sturdy immigrants had already been transforming the tidal marshes into fertile farms for over 60 years with their ingenious system of dikes and aboiteaux.

Are there enough permanent dikes in Quebec?

Hole EB17-02 intersected a weak zone but the main target was impacted by strong shearing and parallel dikes that seemed to dislocate the main mineralization.

The area where flooding could occur on the Isthmus of Chignecto includes 20 kilometres of the Trans-Canada Highway, 20 kilometres of CN Rail tracks, 35 kilometres of electricity lines and 35 kilometres of dikes.

The initiative comes amid increasing calls for something to be done to maintain the land link between New Brunswick and Nova Scotia by raising and reinforcing dikes at the narrow isthmus that joins the provinces.

With a system of dikes and canals, waters are safely directed to the sea whilst urban planning allows floodplains to be kept clear.

An extensive system of dikes and canals has been built to contain the Red River and to irrigate the rich rice-growing delta.

Aplite and porphyry dikes and veins may intrude pegmatites and wall rocks adjacent to intrusions, creating a confused sequence of felsic intrusive apophyses (thin branches or offshoots of igneous bodies) within the aureole of some granites.
