Cyrtodactylus metropolis sp. nov. from Batu Caves massif, Selangor, Peninsular Malaysia is differentiated from all congeners by having a unique suite of morphological and color pattern characteristics. Remarkably, this species has been overlooked despite a plethora of field studies at Batu Caves from 1898 to the present and no specimens had ever been examined until now. As with all other limest...

Three techniques for treating fish ponds with agricultural limestone were evaluated in ponds with clayey soils in Brazil and in ponds with sandy soils in South Africa. Amounts of agricultural limestone equal to the lime requirement of bottom soils were applied by the following methods to each of three ponds: (1) direct application over the pond surface; (2) spread uniformly over the bottom of t...

The kinetics of calcination of a high calcium type of limestone was studied. Ukpilla limestone found in the central region of Nigeria was studied. The limestone composition shows that the limestone has 51.29% calcium oxide and 41.53% loss on ignition and magnesium oxide content of 2.23%. The following parameters were determined; diffusion coefficient of lime layer, and mass transfer coefficient...

Based on differences in the permittivity of coal and limestone rock, a resonant cavity measurement technique is presented for the rapid determination of the proportions of coal and limestone in powdered mixtures. The ratio of the resonant frequency shift and the change in the transmission factor when mixed coal and limestone samples are inserted into the cavity provides a means for estimating t...

Abstract The production of building stones shown an exponential growth in last decades as consequences the demand and developments extraction processing techniques. From several conditioning factors affecting this industry, geological constrains at quarry scale stands out one most important. Globalization increasing competition stone market require large raw material blocks to keep further cost...

During the surface surveys conducted in Şanlıurfa recent years, a large number of reliefs dating back to timeframe from 2 th B.C. 1th were discovered. Dağyamacı reliefs, located 500 m east Harran Plain within Tek Mountains region, are Said unearthed at some quarry-like location. The location where discovered is only limestone quarry that has been dated region. Orthostatic relief sketches, embos...
