Historically wild rice was important economically and spiritually across much of central and eastern Canada, but the antiquity of its use by Native communities is unclear. Unlike plant macrofossils, which have traditionally ...

Paleosecular magnetic changes through a 1.5m section of post-glacial lacustrine deposits are strongly influenced by mineralogy and differential compaction. The sediments chiefly comprise clay and, in the lower one third ...

Specimens of plutonic granitic gneisses have been collected from different locations of the Superior Province. The study of their Koenigsberger ratio (related to natural remanent magnetization) and the theoretical ...

This study presents an X-ray diffraction analysis and Rietveld structural refinement of selected synthetic fluoroperovskite-type compounds including the Na1-xKxMgF3 solid solution series in addition to synthetic analogues ...

The Murun complex contains a number of unusual and mineralogically unique rocks. Many of them are problematic in terms of their genesis and petrographic interpretation. These enigmatic rocks include charoite assemblages, ...

A representative collection of minerals &om two niobium deposits found within the Oka carbonatite complex: the Bond Zone deposit; and the NIOC AN deposit, were analysed using an electron microprobe, and compared with ...

The Sibley Group is an unmetamorphosed Mesoproterozoic red bed sequence, commonly flat lying, that formed in an intracratonic basin between 1450 Ma and 1500 Ma. It covers an area o f 15,000 km^, and reaches a total ...

The Deadhorse Creek ‘Diatreme’ is a Proterozoic vent breccia that probably formed in response to early mid-continent rifting. Following emplacement of the breccia, the western subcomplex experienced three alteration ...

The Paleoproterozoic Rove and Virginia Formations are lithostratigraphically and chronostratigraphically correlative units which comprise the upper sedimentary strata in the Animikie basin. They sharply overlie an intensely ...

Calcite petrofabrics align easily with weak strains, possibly being the most sensitive classical petrofabric indicator. Thus, calcareous sediments may reveal stress trajectories in neotectonic environments. Calcite aligns ...
