Tuffite
a volcanogenic sedimentary rock consisting of volcanogenic material ejected during a volcanic eruption (for example, scoria, ash, pumice, and rock fragments) and sedimentary material mixed with the volcanogenic material. Tuffite may contain rounded fragments of intrusive rocks and also quartz, feldspar, biotite, and organic remains. The cement may be carbonate or argillaceous. Tuffite is used as a building material.

No references found | Oil shales in this field alternate with limestone, marl, claystone and tuffites. The first holes are scheduled on the East Block where a zinc tuffite was intersected four times by diamond drilling, followed by other drilling targets on the East Block, and finally the drill will be moved to the West Block where the DeepEM "in-loop" anomaly of 600 m length revealed in 2003 was confirmed and more precisely located by an InfiniTEM survey just completed. The first three holes are located in the eastern block of the Du Dome-Matagami Property where a zinc tuffite was intersected twice by diamond drilling in 2004; they have intersected the tuffite at two other locations. |
