Sideritic

mainly sideritic BIF with one marl near the base and a package of thin laminated shales toward the top. Another shale (the upper shale interval or USI) occurs above the BIF up to 125.5 m depth and comprises mainly black lam-inated shale. Pyrite nodules occur between 131 and 134 m and pyritic laminae from 134 to 143 m. Both the USI and

Definition and formation: Partings are laminae or beds of noncoal rock, usually mudstone or claystone, in coal beds. They form from sedimentation during flooding of the peat that ultimately became a coal bed. Some coal beds have many partings, some do not. Some partings are regional extent, but most are local.Geochemical classification of terrigenous sands and shales after Herron (1988) Geochemical classification of terrigenous sands and shales is the title of M. Herron's paper in 1988. The scheme was developed for classifying sandstones and shales based on their geochemical composition, which could be determined from log data of at the time new geochemical logging (bore-hole) tools.

An unnecessary name for a manganoan variety of siderite, with up to 40% MnCO3 [Clark, 1993 - "Hey's Mineral Index"]. Pistomesite. Obsolete name for a Mg-bearing variety of siderite with the Fe:Mg atomic ratio ranging from 70:30 to 50:50. Originally reported from Thurnberg Mt., Flachau, Radstadt, Salzburg, Austria.Siderite is a type of volcanic stone that can have many different meanings and uses. There are many different meanings ascribed to siderite, the most popular of which is that it represents strength and courage.showing a type F2 mud-dominated composite particle (MCP) (sideritic rip-up clast) and a type E MCP (chlorite/ siderite) clast in a prodelta mudstone sample. (B) and (D) are secondary electron images.Siderite occurs as clay ironstone, an impure mixture of siderite with clay minerals. It may form concretions or concentric layers. It may also occur as black-band ore, which can form extensive stratified beds admixed with shales, other carbonates, and coal. Siderite is also formed as iron rich waters replace Ca in limestone.The Cambay Shale group is conformable and 220–470 m thick, composed of monotonous grey shales in thin alterations with silty and carbonaceous shales, occasionally sideritic. The Ankleshwar formation of Middle to Upper Eocene is the main stratigraphic unit in terms of hydrocarbon potential.

The phosphate is believed to be an early diagenetic replacement of carbonate concretions, probably penecontemporaneous with Ashfield Shale deposition. The U and F content of the phosphate does not support a marine origin for the formation. Where protected from compression within hard sideritic bands, the phosphatic nodules remain spheroidal.Sideritic ooidal facies and siltstones are the second important reservoir facies in which moderate values of porosity (10-25%) and permeability (1 to >100 mD) are recorded.
