AUTOMATED CALCIMETER AC-280

The AC-280 Automated Calcimeter is a computer-automated multi-sample instrument for determining the ratio of calcite to dolomite in up to 20 core or soil samples. Normal testing time can be from a few minutes to over 45 minutes. The operator can configure test completion to be based on either a preset time increment or completion can be based on stable pressure conditions. All entered and measured data is logged to a file on the computer and can be viewed at any time.

MICRO X-RAY FLUORESCENCE (m-XRF)

This device measures relative elemental variations (qualitative) in solids and liquids by X-ray fluorecence at ultra high resolution (~50 µm scale) under both atmospheric and vacuum conditions.

It can be used in:

• 10 cm pieces of sediment cores
• thin-sections
• water samples
• powders

OPTICAL CATHODOLUMINESCENCE CITL CL 8200-MK 5-1 AND ERI-MERTECH

Cathodoluminescence (CL) is the emission of light from material when it is irradiated with electrons. The technique is used for imaging spatial variations in the trace element composition of natural (e.g. calcite, diamond, feldspar and apatite) and synthetic materials. We have a cold cathode: a) CITL 8200 Mk 5-1 mounted on a Leitz Orthoplan petrological microscope and b) ERI-MRTech mounted on a Olympus BX41 petrological microscope, both available for optical CL studies.

SCANNING ELECTRON MICROSCOPE JEOL JSM7001F

Analytical Thermal Field Emission SEM with a hot (Schottky) electron gun that is optimised for analytical applications. It offers very high beam currents with excellent stability even at lower acceleration voltages. . Its specificities are: High resolution; Multi-purpose specimen chamber; Low Vacuum capability. The SEM is equipped with an Energy dispersive X-ray analyser EDS JED2300 and a Cathodoluminescence detector. This last is used for high resolution work, or for minerals that have a poor or UV light emission.

SAMPLES PREPARATION LABORATORY

The sedimentology laboratory is one of the core laboratories of the DESTE. The laboratory has facility for both wet and dry sample analysis. The wet analysis includes the preparation of samples for textural, mineralogical, geochemical and clay mineralogical analysis. The laboratory has a modern core cutter machine and a deep freezer for storing and archiving the sediment samples and sediment cores. The dry unit of the laboratory has a facility for sieving the sediment samples for grain size distribution, and for dissolving sedimentary rocks in order to separate microfossil. The laboratory is used extensively by the research students/project fellows and at a given time more than 5-6 people work in the laboratory.
