limebato dolomite ordovician

A 1 m thick red brown weathering dolomite contrasting strongly with the light coloured Huk Formation below is present in parts of Oslo at the base of the Elnes Formation. Skaar (1972 p.A142) recognised a local intraformational conglomerate near the base of the limestone consisting of 1 5cm blocks of the underlying grey limestone set in a dolomitic matrix.

 · Grain dolomite, as one of the most important reservoirs of oil and gas, is a hot spot, focus and difficulty in dolomite genesis research field. Since 2010, large-scale doloarenite which can form high-quality reservoirs was discovered in the Ordovician Majiagou …

Missouri Limestone. Fossiliferous Limestone. Calcite Limestone. Commodity: Limestone, a sedimentary rock that is dominantly composed of the calcium-bearing carbonate minerals calcite and dolomite. Calcite is chemically calcium carbonate (formula CaCO3). Dolomite is chemically calcium-magnesium carbonate (formula CaMg (CO3)2).

 · In central Kentucky, Ordovician limestone and dolomite are mined and quarried for construction aggregate. Stone is being produced from the High Bridge Group and the overlying Lexington Limestone. The High Bridge Group consists of three formations: in descending stratigraphic order, the Tyrone Limestone, Oregon Formation, and Camp Nelson Limestone.

ABSTRACT A transition between limestone and dolomite in the MacGregor Member of the Platteville Formation ranges up to a mile in width and is marked by irregular and patchy dolomitization. Locally the dolomitized patches roughly parallel the dominant joint set. There is some evidence of permeability control of dolomitization. Small quantities of epigenetic pyrite appear to have been introduced ...

By the early Ordovician, the Prairie du Chein dolomite rocks form, and in the map below the thickness of the Prairie du Chien dolomite is added to the two Cambrian sandstones to yield rock thicknesses in excess of 2500 feet for parts of Michigan! By the middle

 · Dolomite crystals are commonly 5 μm to 40 μm in size, and are anhedral. After staining, most of them are blue or purple, and are ferroan dolomites. Fossils are absent, and the percentage of terrigenous material, mainly silt and mud, is low.

The 5th sub-member in 5 Member Ordovician Majiagou Formation in Daniudi Gas Field, Ordos Basin, is deposited in an environment consisting of an ancient epicontinental sea, where very fine crystalline dolostone reservoir has developed. In this study, based on the petrological and geochemical characteristics, the genesis of the dolomite developed in M55 were studied by analyzing the …

and its association with dolomite in southern Wisconsin has resulted in many studies focused on the occurrence of dolomite. These studies have attributed the occurrence of dolomite in these Ordovician rocks to a wide range of dolomitization models.

 · A large difference of 0.61‰ was found between dolomite (− 1.61‰) and its precursor, limestone (− 1.05‰) in the late Ordovician Yeoman Formation of the Williston Basin. The low value for dolomite expands the range of literature values by 50%.

dolomite within the Prairie du Chien Group is finely-crystalline (<0.02-0.1 mm) dolomite crystals with unzoned red-orange cathodoluminescence. These small dolomite crystals are ubiquitous, and are over grown and partially replaced by later dolomite phases.

 · Typical dolomite reservoirs exist in the upper assemblage of the Ordovician Majiagou Formation in the southeastern Sulige gas field, Ordos Basin, however, the current understanding of dolomite genesis needs to be clarified. This study confirms the dolomitization ...
