Later on, the Chang'E-2 and Chang'E-3 satellites were successfully launched in 2010 and 2013, respectively. In order to achieve the science objectives, various payloads boarded the spacecraft. The scientific data from these instruments were received by Beijing and Kunming ground stations simultaneously. Up to now, about 5.628 Terabytes of raw data were received totally. A series of research results has been achieved. This paper presents a brief introduction to the main scientific results and latest progress from Chang'E-3 mission.展开更多

A year later on June 21, the project, representing the first scientific drilling of China＇s uranium, was officially launched, and successfully completed on June 17, 2013. A 2818.88 m of drilling depth has broken the previous record 1200 m of exploration depth.展开更多

In order to determine the location, characteristics and activities of the Zhengzhon-Laoyachen fault, shallow seismic prospecting with different exploration depth across the Laoyachen fault was carried out in the northern suburbs of Zhengzhou city in 2006. The images of the subterranean structure and tectonics at depths of 30m- 6000m have been available by applying the combined methods of explosive seismic sources and vibrator seismic sources, as well as the combination of diverse observation systems with different parameters. The outcome indicates that the Laoyachen fault is a normal fault running NW and dipping NE, which offsets stratums ahead of Neogene （N）. However, no fault displacements are found in the interior stratums of Q ＋ N.展开更多

The geological controls of the deposit,and the geophysical and geochemical ore searching indicators are summarized, and a synthetic exploration model, involving data from geology, geophysics and geochemistry and so on, is set up in the paper based on the study on the geological controls of the ores, on the measurement of geophysical properties of the ores and host rocks, on the observation of geophysical field around the mineralized district and on the research of the geochemical characte^ristics of the deposit. It is believed to be of significance to the exploration of the similar deposits in the metallogenic belt.展开更多
