WAN Yu-sheng, DONG Chun-yan, XIE Hang-qiang, ZHENG Jian-ping, LIU Shou-jie,MA Ming-zhu, XIE Shi-wen, REN Peng, SUN Hui-yi, LIU Dun-yi
We carried out integrated geological, geochronological and geochemical studies on typical early Precambrian areas of the North China Craton, such as Anshan-Benxi, eastern Hebei, western Shandong and Yinshan, and synthesized the general geological records of the Archean basement relating to Archean crust formation and evolution of the North China Craton. This study also revealed that the Ordos basement was involved in a widespread late Paleoproterozoic tectono-thermal event. We defined and outlined three ancient terranes containing abundant 3.8~2.6 Ga rocks for the first time in the North China Craton, namely the Eastern Ancient Terrane, Southern Ancient Terrane and Central Ancient Terrane.

22 Multiples Attenuation Approach by F-K and Radon Transform
ZHANG Ya-wei, YAN Jia-yong, LIU Zhen-dong, ZHANG Yong-qian, XU Yao
Multiples is one of common noises in seismic exploration, the techniques of multiples attenuation is a serious problem in seismic data processing. This paper introduced the formations, classifications, characteristics of multiples, and the multiples attenuation in synthetic seismic data in ProMax system. Firstly, NMO correction with the appropriate speed for CDP gathers in t-x domain; Secondly, used F-K transform and Radon transform respectively to convert it to different domains, then attenuated the area where multiples was in new domains; Finally, transformed it to t-x domian through the corresponding inverse transforms to achieve the purposes of the multiples attenuation. By the applying of multiples attenuation in ProMax system, it suggests that different methods of multiples attenuation have advantages and disadvantages, and multiples attenuation in combination with different methods will achieve better results.

28 Short Wave Infrared Spectral Analysis Extraction Alteration Information and Prospecting Practice-A Case Study of Gangcha Gold Deposit, Gansu
PENG Zi-dong,SHEN Jun-feng,CAO Wei-dong,LIU Hai-ming,LI Jin-chun,ZHANG Zhao-yu
Gangcha deposit, a medium-size structure controlled alteration type gold deposit, is located in the western section of Xiahe-Lixian metallogenic belt of West Qinling Orogen. In order to study the alteration mineral of the deposit, short wave infrared spectral mineral analysis technology was applied, and two alteration zones had been identified from wallrocks to ore bodies. In this study: we ① identiied the compositions of muscovite+illite+secondary quartz were close to ore bodies, and kaolinite +dickite +montmorillonite ± illiten were far away from ore bodies; ② found the trends of 1 400 nm, 1 910 nm and 2 200 nm characteristic absorption peak turned to be shallow as it closed to the ore bodies; ③ found the crystallinity trend of illite was better when it closed to ore bodies. These provided new ideas for the further exploration of Gangcha deposit.

40 Gabon Basin Salt Characters and Its Influences on Pre-salt Oil and Gas Exploration
HUANG Xing-wen, HU Xiao-lin, GUO Yun, WANG Ke
Gabon Basin is a typical Atlantic passive margin salt basin, which is subdivided into pre-salt sequence and post-salt sequence by Aptian salt. Inspired by several giant pre-salt discoveries, such as Tupi, Franco, Libra in Brazil deep water, West Africa salt basins such as Gabon, Kwanza have attracted eyes from world major players in recent years. In order to solve pre-salt trap identification difficulties, we analyzed the lithological and petrophysical characters of Gabon salt and its influences on pre-salt imaging and seismic interpretation. Meanwhile, pre-salt in deep water Gabon is less-explored and thus pre-salt source and reservoirs characteristics are not clear. Considering heat conductivity, density and ductility character of salt, we analyzed pre-salt source rock maturity in Gabon deep water and salt influences on pre-salt source rock maturity based on basin modeling; we analyzed salt influences on pre-salt reservoir quality and pointed out deep water Gabon developed high quality pre-salt reservoirs by using new well data; we analyzed salt distribution, deformation and its influences on hydrocarbon charge and preservation, and pointed out that favorable pre-salt exploration areas and favorable areas for post-salt accumulations from pre-salt source. This paper may have some inspiration for other salt basin exploration.

Shao-yu, ZHANG Hai, MENG Chang-zhong, HUANG Tai-zhong LIU De-hua, WANG Biao, ZHOU Li-fang
The Lushan copper deposit occurred in the dark gray or black silty mudstone at the bottom of the Xuanwei Formation (P3x), and the volcano breccia hematite bed at the top of the third section of Emeishan basalt (βP3). These ore-host strata with a new ore type were recognized as new copper mineralized horizons in Guizhou Province. The element zoning sequence in the ore-bearing rock from top to bottom is Ti-Cu-Fe, which is in accordance with the characteristics of the weathering and leaching copper deposit from basalt. The geological characteristics of the Lushan copper deposit was summarized by a detailed study, which provided some new ideas for the exploration of the same type copper deposit.
