The diabase sills are tough igneous rocks that occur as thick layers. In contrast, the sedimentary rocks interlayered with the diabase are riddled with fine fractures and soft minerals and erode easily. Over eons of time, erosion of the soft sedimentary rock undercuts the overlying diabase sill, causing the diabase .

The majority of the mafic intrusions and volcanic rocks in the footwall of the Sudbury Igneous Complex (SIC), which is believed to have formed from a melt sheet produced by the impact of a very large bolide, belong to one of two large mafic igneous suites, viz: the ∼ Ma East Bull Lake (EBL) suite of intrusions or the ∼ Ma Nipissing Diabase suite of : Reid R.

The Lac Panache (Nipissing) gabbro intrudes Huronian metasediments ca. 40 km southwest of the Sudbury Igneous Complex. The gabbro contains disseminated sulfides and is in contact with a chalcopyrite-rich quartz vein that crystallized from highly saline fluids ( ± 3 equivalent wt.% NaCl) at a minimum temperature of ± 27 °C.
The Ramsey Lake conglomerate (H4) also lies near this Ga array, but with more radiogenie lead. Naldrett A. J., and Evensen N. () Petrologic, chemical, isotopic and economic-potential studies of the Nipissing diabase.
Ontario Geol. Surv. Misc. Pap.() Re- OS isotopic systematics of Ni-Cu sulfide ores, Sudbury. The elliptical (60 × 30 km; Ames et al., ) Sudbury structure in Ontario, Canada, occurs at the contact of the Archean Superior Province, and the Early Proterozoic Southern Province (Ames et al.,Card et al., ; Fig.
1A). Contained within the Sudbury structure is the Sudbury basin comprised of the Whitewater group and the Sudbury Igneous Complex (SIC). Deposition of the Huronian Supergroup, dominantly fluvial clastic sediments with local basal volcanic accumulations, began at ∼ Ga in a broad trough that extended far south of the present Lake Huron area atop a large Archean continent that was assembled at ∼ Ga and broken up at ∼ Ga after intrusion of widespread gabbro sheets and dykes including Nipissing diabase.
Nipissing diabase, a basic igneous intrusive rock, occurs as sills and dikes that have intruded igneous and sedimentary rocks of the Canadian Shield. It is the ridges of this rock type that have been designated as SRAs.
Sites for sampling were selected on the basis of. Paleomagnetism of the Nipissing diabase, Cobalt area, Ontario.

Nipissing Diabase sills and baked host sediments of the Coleman Member of the Huronian Supergroup east of Englehart, Ontario, are shown to have a characteristic remanent magnetization direction.
Lake Nipissing (/ ˈ n ɪ p ə s ɪ ŋ /; French: lac Nipissing) is a lake in the Canadian province of has a surface area of km 2 ( sq mi), a mean elevation of m ( ft) above sea level, and is located between the Ottawa River and Georgian Nipissing is the third-largest lake entirely in Ontario.
It is relatively shallow for a large lake, with an average. In the summer ofas part of our summer camping trip up north, we stayed at Mississagi Provincial Park. The park is located about 25 kilometres north of Elliot Lake, Ontario.
Just north of the park is the Cobre Lake Hiking Trail, which is. The Offset Dykes are impact melt-bearing dykes related to the Ga Sudbury impact structure.
Currently, the dykes extend radially outward from—or occur concentrically around—the Sudbury Igneous Complex, which is the remnant of a differentiated impact.
Previous age determinations on this basement complex indicate that it is about 2, m.y. old. Several igneous formations are intrusive into the Huronian formations. The oldest of these is the Nipissing diabase, which forms a complex of sills and dikes throughout the area studied; granophyric differentiates occur at several localities.
Diabase dikes were intruded into unconsolidated sediments at considerable depth, producing round-stone breccias, which are texturally similar to Sudbury breccia. Minor compressional folding occurred prior to emplacement of the Nipissing Diabase Suite at around Ga.
