24. Petrography and Geochemistry of Red Sea Dolomite

Examination of piston cores and, particularly, sediments collected by the Deep Sea Drilling Project has shown that authigenic dolomite occurs in a wide range of sedimentary associations. While the trace to a small percentage of dolomite often encountered in pelagic carbonate sequences may be a result of authigenesis under "normal" deep-sea conditions, the few studies to date seem to indicate th...

Petrography and geochemistry of the Kahrizbeyg intrusion, southwest of Zanjan

The Kahrizbeyg pluton is located northwest of Iran in Central Iran zone. It is emplaced into the Cretaceous limestones in which contact metamorphism has happened. Meanwhile, rock fragments of this pluton are found in conglomerate units of Early Oligocene Lower Red Formation. Therefore, the relative age of pluton is between Cretaceous and Oligocene. The Kahrizbeyg pluton consists of granite and ...

Petrography and element geochemistry of dolomites of Sibzar Formation, east of Neyshabur

The Sibzar Formation (Middle Devonian) is located about 30 km east of Neyshabur and is composed of lower dolostone with intercalations of sandstone, middle basaltic sill and upper dolostone to limy dolostone, with a thickness of 334 m. Based on the crystal size in this formation, three different types of dolomite (D1, D2, Vd) were identified and according to the textural classification of the d...

Petrography and Geochemistry of the Crawfish Inlet and Krestof Island Plutons, Baranof Island, Alaska

The Sanak-Baranof plutonic belt (SBPB) includes a series of biotite tonalite, granodiorite, and granite neartrench plutons that intrude the Campanian to Eocene flysch of the Chugach-Prince William terrane (CPW) for 2100 km along the southern Alaskan margin (Hudson et al., 1979; Hill et al., 1981; Bradley et al., 2003; Haeussler et al., 2003). SBPB intrusions have been interpreted to be the resu...
