High Falls
Guy-Bray, J. and Peredery, W.V., 1971. Field Guide for Excursion 1 - Sudbury Basin. GAC-MAC 1971, 18 p. Stops
2A - Micropegmatite and basal breccia.
Intermingled plagioclase-rich and granophyre-rich varieties are present ; neither shows chilled contacts. Gneiss inclusions derived from the basal breccia consisting of large/small basement fragments (metaseds, granites. gneiss) in a recrystallized pseudo-igneous matrix of quartz, albite, and chloritized anhedral mafic patches - pulverized rock fragments; some planar shock features persist notably in fragments that appear dark gray in colour.
2B - Micropegmatite basal breccia
lens of plag-rich micropegmatite intrudes basal breccia; stoped fragment of basal breccia complete with matrix is enclosed by the micropegmatite; contact is exposed a few feet north of the lens.
2C - Basal breccia and hornfelsic Gray Onaping
2D - Melt Rock and basal breccia
2E - Melt, basal breccia and quartzite
2F - Melt, chilled and chilled-brecciated melt; devitrified glass flows and Gray Onaping

Stop 4 - Discovery site

Stop 5 Copper Cliff offset
Copper Cliff offset
quartz diorite, less than 200 feet wide at this stop; ore grade mineralization is confined to a zone within the dike or at one margin; outer part of the offset dike is finer grained than the interior, which includes the mineralized zone defined by an abundance of sulphide blebs and small, generally amphibolitic inclusions

Stop 6
McKim Fm
thinly beeded turbidite with well preserved flame structures; abundant small pseudomorphs after staurolite imports a reverse graded bedding .; small shatter cones point northwards.

Stop 7 Sudbury breccia, Ramsay Lake and Pecors formations
large inclusions in the breccia; they are dioriented and well rounded by attrition; occasional exotic blocks of units below or above the Ramsay Lake and Pecors; scarce shatter cones in the the Ramsay Lake conglomerate

stop 8
Stop 8
Beds dip 60 Se;prominent current bedding show south facing; shatter cones are several feet in size; each cone has numerous parasitic partial cones; apical angle is about 90 degrees; stereographic projection shows that they have a strong preferred orientation , with conical axes lying in the plane of the bedding plane; the axes point northwards; cone surfaces are only exposed where they parallel the surface of the outcrop; on other surfaces the interesecting crescentric fractures impart a shattered appearance to the rock
