Unlike most of the Jurassic synrift breccias in the Tethyan realm, which are almost exclusively composed of clasts and matrix, the Krasin Breccia is unique in its complex post-depositional filling and cementation (including ubiquitous endostromatolites, radiaxial fibrous calcite, various sedimentary fills) that infer a special depositional and post-depositional by: The present study was designed to test the placer gold potential of the Elliot Lake Group, Ontario, Canada. Pyritic quartz-pebble conglomerates and conglomeratic sandstones of probable fluvial. Read Volume 73 Issue of American Mineralogist. Depositional processes control initial porosity and permeability relationships in basin-filling sedimentary successions. These initial conditions then determine how diagenesis modifies the hydraulic properties of sediments as they undergo burial and lithification.

Depositional Facies and Diagenetic Alteration in a Relict Siliceous Hot-Spring Accumulation: Examples from Yellowstone National Park, U.S.A. Stratabound, uraniferous diagenetic xenotime cements provide a minimum depositional age of 1,±3Ma for the sedimentary Birrindudu Group in the Killi Killi Hills, Tanami Region in northern. The ca. Ga pyritic uraniferous quartz-pebble conglomerate (UQC) of the Matinenda Formation of the Elliot Lake Group, Huronian Supergroup, was used in . These These rocks are evidence that there was very little and isolated amounts of iron deposited with chert during the Precambrian These rocks are evidence that Earth's early atmosphere the same during the Precaibrian These rocks are evidence that oxygen must have been present ined oxygen was not yet present during during the Precambrian.

Highlights Huronian Glaciation Event (HGE) globally occurred during – Ga. HGE followed Siderian BIF-deposition that consumed O 2 generated by photosynthesis. HGE, followed by red beds and positive δ 13 C carb anomalies, resulted from GOE. GOE includes – Ga oceanic oxidation and – Ga atmospheric oxygenation. The nature of the Earth's superficial system dramatically Cited by: Furthermore, interelement ratios (e.g., Co/Ni, Ni/Ag) of the trace element-rich “spongy” and nodular pyrites are also similar to those of typical diagenetic pyrite. LA-ICP-MS imaging of pyrrhotite in the same rocks reveals multistage growth in this mineral as well, with the earlier generation having higher concentrations of Ag, Sb, Pb, Tl Cited by: Diagenetic pyrite in the mudstones and ironstones of the Lower Jurassic Cleveland Ironstone Formation of eastern England exhibits two distinct morphologies: framboidal pyrite, commonly associated with organic matter, and euhedral pyrite, associated with detrital clay by: The analysed sample is a uraniferous bitumen-bearing feldspathic quartz-pebble conglomerate from the Matinenda Formation of the lower Huronian Supergroup at Elliot Lake in Canada ().The host Huronian Supergroup is composed of up to 10 km of fluvial, shallow marine, and possibly lacustrine, mainly siliciclastic sedimentary rocks deposited between and Ga in a rift basin (Fralick and Cited by:
