The author considered that Wadi Bayhan deposit belong to magmatic PGE-bearing Cu-Ni sulphide deposit. Based on above conclusion, the genetic model for Wadi Bayhan deposit was built, and the prospective potential was assessed by the author Key wordsWadi Bayhan；Jinchuan；Magmatic PGE-bearing Cu-Ni sulphide deposits 内内 容容 提提 要要 金川岩浆岩型含铂族元素铜镍硫化物矿床是中国最大的一个铜镍硫化物 矿床，其镍储量占世界第三位。 本文通过系统地对比也门Wadi Bayhan铜镍矿床与金川铜镍硫化物矿床的 区域地质背景，成矿地质条件，以及矿床地质地球化学特征，认为二者存在着 许多相似特点，初步判断Wadi Bayhan铜镍矿床也属含铂族元素铜镍硫化物岩 浆矿床，在此基础上，建立了其成因模式，并评述了找矿潜力。 关键词关键词Wadi Bayhan；金川；含铂族元素铜镍硫化物矿床 Correlation Study on the Magmatic PGE-bearing Cu-Ni sulphide deposits in Wadi Bayhan of Yemen and Jinchuan of China 1 Preface 1 Objectives Jinchuan deposit, which has similar characteristics with Wadi Bayhan magmatic PGE-bearing Cu-Ni sulphide deposit, has profound economic importance. However, we have poor data on Wadi Bayhan deposit. The aim of this study therefore, is to compare the two deposits and show their similarities. Basically the main objectives are 1- To find out the similar characteristics of the Wadi Bayhan deposit in southeast Yemen and Jinchuan deposit of northwest China. 2- Determine the age of mafic-ultramafic intrusions of the Wadi Bayhan by Ar/Ar isotopic analysis. 3- Discuss the genesis of Wadi Bayhan deposit. 4- Assess ore prospects of Wadi Bayhan deposit in the future. 2 Location of the study areas The Wadi Bayhan Cu-Ni deposit is located in Masswarh area of southeastern part of the Republic of Yemen, about 60 km NW to Al-Bayda city in Al-Bayda uplift terrane at the southeast margin of the Arabian-Nubian Shield. It must be noted that the target object located in Wadi Bayhan extends to the area of approximately 47 km length and 43 km width. Topographically this study area has no difficult terrain. The main roads passes through the Valley of Bayhan to the eastern part of the body and in some valleys that affect the Valley such as Wadi AL-tum and Wadi Themed are available. 吉林大学硕士学位论文 Moteea Anwar Abdull Malik Al-Sha 2 Oman Quaternary sediments Tertiary intrusions Tertiary volcanics Cretaceous sediments Jurassic sediments Paleozoic sediments Precambrian rocks Major faults Tertiary sediments Quaternary volcanics Legend 0 100km Saudi Arabia Yemen Gulf of Aden Red Sea Marib 13 15 17 434547495153 Suqatra Al Mukalla Aden Hudaidah Al Ghaythah Ramlat as Sabatayn N Study area Bayda terrane Fig.1 Geological map of Republic of Yemen with location of Wadi Bayhan However, Jinchuan is located in Gansu Province in northwest China, about 1200 km west Beijing. The deposit is located in the Longshou Mountain uplifted terrene at the southwest margin of the Alxa Block to the north of the Northern Qilian Orogenic Belt. The Longshou Mountain uplifted terrene is bordered by Central Asia Orogenic Belt on the north and the Qilian-Qinling Orogenic Belt on the south Fig. 2.

Yang, J., et al., 1988-1991 3 Geographical and Climatic Features The different landscapes of the Republic of Yemen can be grouped into four main geographical and climatological regions 1. The Coastal Plains these plains are located in the west and southwestern part of the country, and are flat and slightly slopy with hot climate and low rainfall 50 mm/year. 2. The Yemen Mountain Massif it is high with very irregular and dissected topography, with elevation ranging from a few hundred meters to 1,000 m above sea level. The climate varies from hot at lower level to cool at the highest elevation. Wadi Bayhan is located in this massif and of course is easy to reach. 3. The Eastern Plateau Region most of the eastern half of the country is covered by this plateau. Its elevation decreases from 1200-1800m at the major 吉林大学硕士学位论文 Moteea Anwar Abdull Malik Al-Sha 4 watershed lines to 900m in the northern desert border and to a lower sea level on the coast. In general its climate is hot and dry. 4. The Islands The most important of all the islands is Socotra, where more exuberant flora and fauna can be found than in any other region in Yemen. 4 The workload involved 4.1 Office work extraction Anomaly estimated location Total Magnetic Map from the interpretation of geophysical ination for Wadi Bayhan with a scale of 150,000; extraction of satellite pictures, drawing geographical map with a scale of 150,000 have been undertaken. Besides, spreading geophysical anomalies on the topographic map and geological map, as well as mineralogical and geographical studies coupled with readings in previous studies about the study area have been conducted. 4.2 Field work One trip was carried out during the research activity in 2003 to Wadi Bayhan. Systematic regional and detailed ground traverse were carried out using Geological map Al-Bayda sheet at scales of 1250,000 and 1100,000. During 17 days of the field work, a total of 135 rock samples were collected from the outcrops representing the various lithological units or ores in the area and 75 samples were analysed in ALS Laboratory in Canada Table. 1.
