Statistical methods applied to geochemistry It is assumed in the above discussion that the samples are drawn from populations with equal standard deviations. If this is not the case, a reaaonable approximation to a 95% confidence interval can be obtained by replacing t,.,,, by the t’ of the previous section.

Ervamaa, Pentti () The Petolahti diabase and associated nickel-copper-pyrrhotite ore, Finland. Bulletin de la Commission Géologique de Finlande94 pages. The nickel deposit of Petolahti (Pd, ppb) in a postsvecokarelian diabase dike has platinum-group element values close to those of Hitura (Pd, ppb), but the Pd/Ir ratio of Hitura () is much lower than that of Petolahti ().Cited by: 8.

origin. The Vuonos mine of the Outokumpu complex produced nickel sulfide ore in the *s. The complex at Outokumpu is composed of hydrothermally altered ultramafic rocks (serpentinites, carbonate rocks, and cherts as alteration products) associated with massive volcanogenic Cu-Zn-Co-pyrite deposits and separate nickel sulfide : G.

In the sulfide deposits nickel occurs as pentlandite (Fe, Ni) oSs, associated with pyrrhotite, FenSn+t, and chalcopyrite, CuFeS. 2• Nickel also occurs in minor amounts in the following sul­ fides: Polydymite, millerite, siegenite, bravoite, and : Ethel M.

Pratt, Henry Rowland Cornwall. These observations agree with those on the distribution of nickel in the Nipissing diabase at Cobalt, Ontario, and in the Skaergaard intrusion of East Greenland.

On the basis of the observed nickel concentration in chill border samples it can be concluded that the presence of nickel mineralization associated with the Nipissing diabase is not caused by an abnormal nickel concentration in the Cited by: million Ibs of nickel and million Ibs of lead.

Nickel Sulfide Ores and Impact Melts is designed to emphasize concepts that can be applied across a broad range of ore deposit types beyond Sudbury and nickel deposit geology. Northeast-trending, linear magnetic lows are interpreted to reflect reversely magnetized diabase dikes and have properties consistent with Keweenawan rocks.

The interpreted dikes are cut in places by normally magnetized mafic–ultramafic rocks, suggesting that the latter represent younger Keweenawan by: 7. H.E. Harris Coin Folder Book for Buffalo Nickel US Coins This 3 panel book comes with all slots needed to complete this series of coins.

It should be understood that the ages given for the deposits do not refer to secondary. THIS PAPER presents some analyses of diabases from a number of metallogenic provinces in Canada and the United States.

MetalsTech acquired 52 mining claims covering hectares, with hectares covering the Nipissing Diabase, a geological structure for high-grade cobalt, silver and nickel Overview The Rusty Lake Project is located in the Leith township, 30km south of the Gowganda Mining camp and about 70km from the Company’s Bay Lake high-grade cobalt project.

In Ontario, silver ores have been found in veins in preCambrian sedimentary rocks and Keewatin greenstone, intruded by diabase sills and dikes; silver veins are found also in the diabase. The vein matter in the Cobalt area is mostly calcite, and the silver minerals (native, argentite, dyscrasite and others) are usually associated with cobalt.

A dark-colored Diabase Dike intruded volcanic rock in a highway cut on Highway 72 about three miles west of Fredericktown, Missouri. Chemically basic Diabase and Gabbro magmas were the last verified and widespread igneous intrusive event here during Precambrian time, to billion years ago.

48 LEBANON COUNTY Most interesting minerals: mag- netite crystals; zeolite crystals; garnets. Geology: The minerals found at Cornwall are associated with two major rock types: diabase and limestone. Diabase is an igneous rock of dark green color containing feldspars and pyroxenes, with minor amounts of biotite and hornblende.

Petrology. Lamproites form from partially melted mantle at depths exceeding km. The molten material is forced to the surface in volcanic pipes, bringing with it xenoliths and diamonds from the harzburgitic peridotite or eclogite mantle regions where diamond formation is.

Predating or associated with those fluids are vertical dikes of porphyritic intrusive rocks from which this deposit type derives its name. In later stages, circulating meteoric fluids may interact with the magmatic fluids. Successive envelopes of hydrothermal alteration. diabase dike: near: Lithology Comments.

Experienced gold prospectors rarely look for gold, but rather look for rocks and rock formations that are known to hold gold. Gold is most often found in quartz rock.

The ultramafic intrusions in the TNB, which are associated with the nickel deposits, have been shown to be chemically and isotopically different from the mafic-ultramafic volcanic rocks (Bah Lake assemblage) at the top of the Ospwagan Group, which hosts the intrusions (CAMIRO report, Project 97E).

The Clipper Gap pluton, composed mostly of quartz monzonite with minor granite, granodiorite, and crosscutting alaskite dikes, intrudes Paleozoic western facies strata.

A narrow zone of contact metamorphism is present at the intrusive-sediment contact. No. Malax, Ostrobothnia, Finland: Other/historical names associated with this locality. Many LIPs have an associated radiating diabase dyke swarm, which typically converges on a cratonic margin, identifies a mantle plume centre, and is linked to breakup or attempted breakup to form that cratonic margin.

We hypothesize that every major breakup margin in Canada can be associated with a LIP, and we attempt to identify this by: Oil shale is a sedimentary rock containing solid and combustible organic matter (kerogen).

Oil shale can be burned as any other fossil fuel or it can be heated without oxygen to extract shale oil. Oil shale (variery Kukersite) from Estonia is very rich in fossils (bryozoans, trilobites, brachiopods). The centre of the claim is over metres west of the Keeley-Frontier deposit (Figure 1) and approximately km south of the Bellellen Mine, which boasts an average grade of % cobalt and % nickel from over 12 tons of ore that were once shipped (McIlwaine, ).
