Core Library (Room temperature)

cold room

 

This has an area of 32.5 m2 and is housing about 600 meters of cores the cores at room temperature. Currently, it is . As and when more cores arrive, the storage capacity can be increased by additional stacks.

Cold room

 

 The cold room has two components.

The large part has a dimension of 9’-8” x 9’-8” x 8’ and maintains a temperature of +5 °C.

A smaller and independent part with a dimension of 5’-10” x 9’-8” x 8’-10.25” maintains a temperature of -18 °C. 

Stainless steel racks are used to keep the cores inside the cold room

The core analysis lab houses the Drill core scanner which is used for continuous measurement of gamma-ray activity, concentrations of K, U, Th and magnetic susceptibility of drill cores.

The measurement of gamma-ray activity is based on the capture of emitted gamma quanta in scintillation detector. the gamma quanta are transformed into electric pulses. The queue of electric pulses is analysed consequently.

The measurement of magnetic susceptibility is done using air-cored coil as a part of the electric oscillator.

Stereozoom microscope by virtue of its twin eyepieces, allows you to view your specimen with both eyes and get a much more accurate view of its surface. It can efficiently handle the viewing of solid specimens of any material from paper to insects to gemstones. Its zoom feature will give you magnification of between ten and forty times, making the tiniest details of a specimen’s surface clearly visible for analyzing.

Petrological microscope (attached with image analysis system) For the measurement of the optical properties of minerals the petrographic microscope is the most important instrument available to mineralogists. Computerised petrographical image analysis (PIA) is available using modern PIA software packages. Digital petrographical images recorded from macrophotography, optical microscopy and scanning electron microscopy can be processed to provide a wide variety of quantitative information on mineral fabric, modal mineralogy and porosity.

Bartington Magnetic Susceptibility Meter is a portable measuring meter which displays the magnetic susceptibility value of materials when brought within the influence of the sensor. Each sensor is designed for a specific application and sample type. An RS232 serial interface allows the instrument to operate in conjunction with custom PC compatible software running on a PC or a portable data logger.

Wet lab

This lab is being used for wet analysis of cores such as grain size analysis and sample preparation for clay mineralogical analysis. Instruments in this lab are:

Digital flame photometer: It operates on the principle of Flame photometry (Flame Emission Spectroscopy). A sample diluted with distilled water is nebulized and aspirated into blue flame of LPG-Air mixture. The intensity of emission transmitted through filter for an element compared to that of the blank with which the instrument is standardized, directly indicates concentration of the element in the sample.

Centrifuge

pH/conductivity/ion analyzer: The conductivity measurement involves AC current measurement through a column of solution under an external reference AC voltage source. When passed through a known series resistance, the current furnishes voltage output which is a measure of conductance. pH determination involves determination of millivolts developed across a pair of electrodes (glass and calomel) when dipped into a solution.
