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. The Barakar and Raniganj Formation of the Damuda Group constitute the most important coal bearing rock formations. All of the Gondwana coal is of bituminous variety. • Iron Ore. About 760m thick ferruginous shales, known as the "Iron stones shales". These shales form a diposit of sideritic iron ore which contains about 40-50% iron. • Clay.

The presence of siderit e causes a significant shift in the NMR T2 relaxation times and a subsequent decrease in NMR log permeability estimation. The shift to faster T2 relaxation time is primarily due to iron content in the siderite. NMR total porosity is unaffected byBivalves: A-C: Oysters preserved in growth position preserved in sideritic sandstone matrix; found on Breezy Point, NY.

It is made of thick cohesive dark-grey mudstone with abundant fossil content. The beds are highly carbonaceous and occasionally contain coal beds up to 5 cm thickness. Scattered sideritic nodules are common. The mudstones contain abundant logs up to 2.5 m length, rooted trees and carbonaceous detritus and a brackish to marine microfauna.the sideritic-kaolinitic beds ("Mánfa Siderite") found in the Central Mecsek Moun-tains. In both cases volcanic origin and a Middle Triassic age of these formations were inferred (Wéber 1965, 1978; Nagy and Ravasz-Baranyai 1968); however, these interpretations were not supported by unequivocal analytical results. Despite this,Sensitivity of MR imaging for the detection of siderotic nodules was improved with use of GRE pulse sequences with longer TEs of 9 msec or greater (80%) versus 4-5 msec (31%); however, there was no significant increased frequency of HCC or dysplastic nodules in patients with pathologically proved si …
