â â â  abstract â  in this study, 129 samples of the qom formation in kaltakeh, south east mahneshan, were investigated. the thickness of qom formation in the examined section is 565m and comprises of limestone, sandy limestone, marl, shale and argillaceous limestone . at this locality, the qom sediments disconformably overlies the lower red formation and underlies the upper red formation. amon...

the qom formation in southwest kashan in sanandaj-sirjan fore arc basin has a thickness of 190 meters and is composed of medium to thick and massive bedded limestone, marly limestone, sandy limestone, marl and coglomerates. study of these deposits led to recognition of nine microfacies related to a carbonate platform. the high presence of perforate foraminifera in most of the recognized microfa...

The work aimed at determining the effects of applying different blends between liquid molasses and agricultural limestone on water quality growth performance Nile tilapia juveniles, Oreochromis niloticus. study employed 24 indoor tanks 100 L outdoor 250 L. Four control groups were set up (no product applied, only molasses, limestone, molasses-limestone blend with 48% but no fish) two experiment...

The Lower Globigerina Limestone Member, the oldest member of Formation, outcrops over most Maltese archipelago, notably Malta. It has provided islands’ main building material since Neolithic period. This paper makes available a corpus findings relating to geochemistry, mineralogy and textural properties this limestone—mostly unpublished undertaken nearly three decades ago—which provide useful s...

Abstract Minimal interference with historical material and maximum preservation is one of the basic principles scientific restoration conservation monuments cultural heritage. The creation nanoscale microscale inorganic coatings a promising way to protect limestone marble heritage objects. We conducted laboratory testing method for stimulating biogenic mineral formation on surface limestone-mas...

The release into the deep ocean of an emulsion of liquid carbon dioxide-in-seawater stabilized by fine particles of pulverized limestone (CaCO3) is modeled. The emulsion is denser than seawater, hence, it will sink deeper from the injection point, increasing the sequestration period. Also, the presence of CaCO3 will partially buffer the carbonic acid that results when the emulsion eventually di...

Argillaceous Lindsay limestone is the geologic storage formation that will be encountered at the site for the construction of a deep ground repository in Ontario, Canada, for the storage of low to intermediate level nuclear waste. The permeability of the Lindsay limestone is a key parameter that will influence the long-term movement of radionuclides from the repository to the geosphere. This pa...

Quarrying in Scioto Township, Delaware County, Ohio, in 1966-67 uncovered an area of well-developed ripple marks at the top of the Columbus Limestone (Middle Devonian) and beneath a few inches of "bone bed" at the base of the overlying Delaware Limestone. The ripples averaged about 19 inches in wavelength and 1.5 inches in ripple height; they had smoothly rounded crests and were notably symmetr...
