... and 100 miles long; and between these a synclinorium of Timiskaming conglomerate and graywacke more than 125 miles long. North of the rocks of the Abitibi Series, however, a zone of sediments believed to be partly Timiskaming and partly pre-Timiskaming has been traced discontinuously by remapping from...

...JAMES ERIC LLOYD EVANS Abstract The porphyry of the Porcupine district, Ontario, has been considered pre-Timiskaming by some and post-Timiskaming by others. A detailed study reveals that it is the result of two processes—igneous intrusion and metasomatic replacement—separated by a period...

... (volcaniclastic and turbiditic sedimentary rocks) assemblage rocks exhibit three major foliations (S 2 , S 3 , S 4 , plus a late constrictional fabric), of which S 3 and S 4 are also present in younger Timiskaming assemblage sedimentary rocks. Pre-Timiskaming folding has long been recognized in Tisdale assemblage...

...F. Corfu; S. L. Jackson; R. H. Sutcliffe Abstract The paper presents U–Pb ages for zircons of the calc-alkalic to alkalic igneous suite and associated alluvial–fluvial sedimentary rocks of the Timiskaming Group in the late Archean Abitibi greenstone belt, Superior Province. The Timiskaming Group...

... The sedimentary rocks of the Timiskaming assemblage (≤ 900 m thick) are only distributed along the north side of the Destor-Porcupine fault zone and unconformably overlie the Porcupine and Tisdale assemblages ( Hurst, 1939 ; Ferguson et al., 1968 ). The Timiskaming angular unconformity cuts both...

... facies. Field relationships and radioisotope ages of intrusions indicate that gold emplacement occurred over a span of at least 7 m.y. Depositional events that predated formation of the Timiskaming unconformity surface are manifested by auriferous clasts of detrital pyrite, banded quartz sulfide...

... Formation of the Timiskaming outlier greatly reduces the distribution of these siliciclastics, and documents a greater spread of shallow-water carbonate of Richmondian age. As revised, the Dawson Point Formation contains two informal members: a deep-water graptolitic shale that grades upward into shallow...

... characteristics of the Midway sequence are generally similar to those of the Timiskaming Group and Timiskaming-type rocks in Canada, and more specifically to those of the Shebandowan Group in the Thunder Bay district. This similarity implies that the latest Archean tectonic and magmatic history of the western...

... by extensive carbonate and chlorite alteration, strong south-dipping foliations, and steep lineations. These features formed during two ductile deformation increments, D 2 and D 3 , that occurred after deposition of Timiskaming assemblage sediments.

...Marc I. Legault; Keiko Hattori Abstract Four types of igneous clasts from Timiskaming conglomerates of the Kirkland Lake area are identified: calc-alkaline porphyry, trachyte (K 2 O + N 2 O > 7.25 wt.%), trondhjemite, and tholeiitic basalt. Clasts derived from quartz–carbonate veins...

...J. J. Veillette Abstract Measurements at some 300 cross-striated sites in the Abitibi–Timiskaming area of Quebec and Ontario revealed two former directions of ice flow: an older west-southwest one (230–270°) in the extreme western part of the area, and a younger, widespread south-southwest one (180...
