Riverside Resources stakes High Lake. ET - News Release. Mr. John-Mark Staude reports. RIVERSIDE STAKES THE HIGH LAKE GREENSTONE BELT . The Lynn Lake greenstone belt is a by km domain of metavolcanic, metasedimentary, and plu- tonic rocks extending from Laurie Lake in the west to Magrath Lake in the east (Gilbert et al., ). It lies in the center of a larger, km-long, lithostruc- tural belt extending northeast from the La Ronge, Saskatchewan, area.
Geology and alteration associated with the Hamlin Lake VMS system, Shebandowan Greenstone belt, Northwestern Ontario, Canada. View/ Open. (Mb) Date Author. Shute, Amy Lynn. Degree. Master of Science. Discipline Geology. Subject Geochemistry Petrology Hydrothermal alteration Northwestern Ontario. The MacLellan and Dot Lake gold deposits are located about 7 km northeast of the town of Lynn Lake within the Paleoproterozoic Lynn Lake greenstone belt. Gold mineralization is hosted by a unique strati-graphic succession know as the Agassiz Metallotect (Fedikow and Gale, ), a subdivision of the metavolcanic and metavolcaniclastic Wasekwan.

The Lynn Lake greenstone belt is a supracrustal sequence within the Reindeer Zone that has been interpreted to represent a series of unique, juxtaposed, juvenile and contaminated oceanic terranes (i.e., Northern, Southern, and New Fox Terranes) that accreted onto the Hearne margin between and Ma (Zwanzig et al., ).Geochemical (Peck and Smith,Zwanzig, ) and Cited by: 2.
The Paleoproterozoic (ca. Ma) Lynn Lake greenstone belt of northern Manitoba, Canada, has been previously characterized as comprising a series of tectonically juxtaposed intra-oceanic-derived metavolcanic rocks. The results of more recent local and regional studies, however, support a significant contribution of continental crust during formation of the metasedimentary, metavolcanic.
FIIIb felsic metavolcanic rocks exhibit pronounced negative Eu anomalies, low Zr/Y, high abundances of HFS elements, and low abundances of Sr. Examples occur in the Kamiskotia, Kidd Creek, Matagami, and Noranda mining districts, the Garrison Subgroup in the Abitibi Belt, and at the South Bay mine in the Confederation Lake area of the Uchi Belt.
Gold mineralization in the Lynn Lake greenstone belt is hosted by mafic and felsic metavolcanic rocks affected by 2 D shear zones. The delineation of D 2 shear zones within the greenstone belt significantly increases the amount of underexplored gold-prospective stratigraphy in the Lynn Lake belt beyond the Johnson Shear Zone.

The units sampled were felsic metavolcanic rocks from the upper third of the sequence (Middle Felsic Group) and a felsic pluton (the Stephen Lake stock) intruded into these metavolcanics.
A Rb/Sr whole rock isochron from the Stephen Lake stock yielded an age of ± 96 Ma with an initial 87 Sr/ 86 Sr ratio of This date is interpreted.

The Lynn Lake greenstone belt has been traditionally divided into east-trending northern and southern belts, which are separated by felsic intrusive rocks (Fig. GS). Based on recent trace-element geochemistry (see Zwanzig et al., ) and Nd isotopic results, however, a three-fold subdivision of the metavolcanic rocks is favoured.

The Flin Flon-Glennie Complex or Flin Flon Greenstone Belt, extends over a km interval on the southern margin of the Trans-Hudson orogen in northern Manitoba and Saskatchewan, hosts clusters of volcanic hosted massive sulphide (VHMS) copper-zinc-gold deposits surrounding Flin Flon, Snow Lake - km to the east of Flin Flon, Hanson Lake - 60 km west of Flin Flon and Sherridon.

The metavolcanic component of this greenstone belt includes abundant mafic (tholeiitic, calc-alkalic and minor alkalic) to felsic (mostly calc-alkalic) varieties. The North Bay Granite Suite is situated in southern and central Newfoundland in the southeastern corner of the Hermitage Flexure, which is a sinuous belt of Lower Paleozoic metasedimentary and metavolcanic rocks.

The Paleoproterozoic Lynn Lake and Rusty Lake greenstone belts occur in the interior (Reindeer) zone of the Trans-Hudson Orogen, that is, in the zone formed as new ocean floor, or in oceanic to continental volcanic arcs and related marine and continental sedimentary basins.
Metavolcanic rocks in the Lynn Lake – Rusty Lake.Plutonic rocks of the La Ronge-Lynn Lake Belt in the Reindeer Lake area consist mainly of homogeneous diorite, trondhjcmite, and granite (Stauffer er al. ). To the southeast of Reindeer Lake, Harper () and Maxeiner () report the presence of voluminous composite plutons of monzonitic, granodioritic.
