Experimental and Obserbational Systems

1. Earth's Material Composition and Property Analysis System

This system include a series of laboratories to do material composition analyses, radioactive and stable isotope measuring, composition and structure micro-area analyses, rock magnetism and paleomagnetism, fluid inclusions, and high pressure and high temperature, having more than 20 sets (suits) of large-scale equipment such as X-ray fluorescence spectrometer, plasma mass-spectrometer, solid mass-spetrometer, gas mass-spectrometer, electron microprobe, X-ray diffractometer, low vacuum scanning electron microscope, rock superconductivity magnetometer, geomagnetic intensity meter, low-temperature magnetic measuring system, 3GPa high temperatures and pressures three axes rheologic meter, and gas three axes rheologic meter. The fluid inclusion laboratory has perfect facilities and advanced research means. The paleomagnetism laboratory with all kinds of test instruments is equipped with a 20M2 zero-magnetism space, and the quality of its test data has been accepted by colleagues at home and abroad.

2. Earht's Deep Structure Observational System

In this system the wide frequency band seismic array laboratory has more than 200 suits of 24 digital wide frequency band seismologs, of which 100 ones are Chinese products, DS-24 collecting System and Wide Frequency (20Hz-20s) Meismolog, and 102 ones are foreign products, RefTek 72A-08 Collecting System and 130-1 Collecting System universally employed by IRIS and CMG-3ESP (50Hz-30s) Seismometer of Graf. A data-processing system of the international standard has been established. In addition, there are LaCoste gravity meter, telluric electric-Magnetic sounding meter and other shallow geophysical instruments.

3. Geological Dating System

This is a complete geological dting system with a series of dating means such as photoluminescence, 14C, U series, U-Pb, Pb-Sr, Sm-Nd, re-Os and Ar-Ar methods. There are thermoluminescence-photoluminescence meter, high accuracy liquid scintillation counter, hot surface ionizing isotope mass-spectrometer, solid isotope mass-spectrometer, multichannel electro-inductance coupling plasma mass-spectrometer, inert gas mass-spectrometer and their corresponding laboratories. Nanometer ion microprobe and accelerator mass-spectrometer are planning to be introduced to perform high accuracy micro-area chronologic study.

4. Geomagnetic Observatory Chain

This chain is form Mohe Observatory on the north though Beijing ( the Ming Tombs) Observatory to Sanya Observatory on the south and evento Antarctic Observation, a part of the longest meridianal geomagnetic observatory chain in the world, and has good observation foundation. Beijing Observatory that has been digitizing is a member of the International Geomagnetic Observatory Network and the datum observatory of geomagnetic observation in China . At persent, some basic facilities and instruments (e. g., absolute observation instruments, relative recording instruments, data-processing system, data transmitting and receiving equipment, pulsation instrument, and mobile observation instruments) in the chain have being modified and upgraded to build a observation system to conform the international development trend.

5. Palaeoenvironmetnal Data Analysis System

This system devotes itself to study Cenozoic geological environmental evolution and globe changes. It includes a series of laboratories to do with grain size, magnetic susceptibility, silicate iron, sporopollen, lake sediment, lake drilling, palaeoecology, cosmogenic nuclide, environmental analysis, 14C dating and photoluminescence dating, with is equipped with grain size analysis meter, magnetic susceptibility measuring meter, thermoluminescence-photoluminescence meter and so on. There are a MAT253 stable isotope mass spectrometer and its corresponding stable isotope laboratory and chemical laboratory.

6. Data Processing and Computing system

It has multiple larger data-processing systems, including molecular dynamics parallel computing system, seismic imaging and oil-gas resource modeling computing system, mantle dynamics parallel computing system, petroleum seismic data processing system, and seismic data processing and interpreting system. The World Geophysical Data Center (WDC-D) is also attached to this system.
