巴基斯坦伊斯兰共和国地质构造与区域成矿

巴摹斯坦伊斯兰共和国位于南亚次大陆的西北部,东与印度接壤,东北与中国为邻,西北与阿富汗交界,西与伊朗毗邻,南临阿拉伯湾,海岸线长980 km,面积79.6万km~2.全境版图狭长,北部和西部是山地与高原,占全国面积59%,其中蒂里奇米尔峰海拔7 690 m,为全国最高峰;东南部为印度河平原,地势低平.印度河横贯南北,流入阿拉伯湾.巴基斯坦处于亚热带,山地高原地区冬寒夏凉,但温差甚大,而平原地区则冬暖夏热,每年6、7月份最热,气温高达40℃以上.除北部印度河上游雨量尚丰沛外,其他地区年平均降水量不足250 mm,特别是西南部和东南部为大片沙漠.     

Lead isotope signatures of Pb-Zn sulfide mineralization in the Reshian-Lamnian area of Azad Jammu and Kashmir,Pakistan

The Reshian-Lamnian area within the Hazara-Kashmir syntaxis in Pakistan is composed mainly of the rocks of the Salkhala, Panjal and Murree formations. Base metal sulfide mineralization in the form of sphalerite and galena with lesser amounts of chalcopyrite and pyrite is present within the Salkhala Formation of the study area. Chemically all these ore phases are homogeneous in composition. The Pb isotopic composition of galena from the area suggests that there is very little or negligible variation in the ratios of ²⁰⁶Pb/²⁰⁴Pb, ²⁰⁷Pb/²⁰⁴Pb and ²⁰⁸Pb/²⁰⁴Pb. Modal ages ranging from 509 to 562 Ma and the μ values of 10.71 to 10.93 have been calculated for the studied Pb-Zn mineralization. On the basis of field features, mineralogy and Pb-isotope signatures, it is concluded that the Pb-Zn sulfide mineralization in the Reshian-Lamnia area is pre-Himalayan in age and can be correlated with the Cambro-Ordovician (Pan-African) orogenic event.     

Study on the geochemical correlation of crude oils of Palaeocene and Jurassic ages from the Potowar Indus Basin in northern Pakistan

This study deals with a detailed geochemical characterization of three crude oils from the Upper Indus Basin, Punjab, Pakistan. The samples were obtained from three productive oil fields of the Datta Formation (Jurassic), Lochhart (Palaeocene) and the Dhak Pass zone (Palaeocene). The GC parameters for and the bulk properties of Datta Formation oils are essentially coincident with those of the oils from the Dhak Pass Formation in the Upper Indus Basin, Pakistan and the oils likely originate from a marine source rock. In contrast, the Lockhart Formation oils show different behaviors and seem to be originated from dirty carbonate rocks although all three crude oils are mature, being of non-biodegraded and somewhat mixed organic matter origin. Low Pr/Ph values and high C₃₅ homohopane index for the Lockhart Formation oils suggest a source of anoxic environment with low Eh while oils from the Datta Formation and Dhak Pass Formation showed different trends, i.e., lower values of C₃₅ homohopane index indicating different depositional environment than oil from the Lockhart Formation. All three crude oils from the Upper Indus Basin are mature for the hopane ratios, i.e., Ts/Ts+Tm, C₃₂22S/(S+R) and C₃₀ αβ/(αβ+βα) and sterane ratios, i.e., C₂₉22S/(S+R) and C₂₉ββ/(ββ+αα) but oils from the Lockhart Formation seem to be less mature than those from the Palaeocene and Datta Formation according to plots like API° vs. homohopane Index, Pr/Ph vs. sterane. The relative composition of 5α(H), 14β(H), 17β(H)-24-ethylecholestanes and the C₂₉20S/20S+20R index, indicate that all three crude oils are equally mature, which makes it unlikely with respect to the above said plots. This difference is may be due to the migratory chromatography which alters the concentrations of sterane and hoapnes and hence gives different results. These oils do not exhibit UCM and have complete n-alkane profiles indicating non-biodegradation.     

恩怨未到了结时——针锋相对的印度、巴基斯坦海军

2008年11月26日发生的“孟买血案”震惊世界。据相关媒体报道，恐怖分子是从海上渗人发动袭击的。这次恐怖袭击事件背后的真相隐藏在层层迷雾之中，无法揭晓，给本来略有缓和的印巴关系又投下了一层浓厚的阴影。一时间印巴边境地区剑拔弩张，两国相邻海域更是战云密布。两国海军纷纷加强战备，南亚海域气氛空前紧张。     

天然与水合物勘探开发亚洲各国各领风骚

国土资源网消息 天然气水合物作为一种清洁能源，20世纪90年代，亚洲的日本、巴基斯坦、印度、韩国等国就开始进行此方面的调查与资源评估工作。作为一个资源极度贫乏的国家，日本目前正在竭尽全力为保障能源安全尽可能“多”地和尽可能“早”地求助于天然气水合物，并花大力气力求在勘探开发方面取得突破。     

南亚茶不可或缺的生活必需品

印度和巴基斯坦原本都不生产茶，英属印度(现在印度、巴基斯坦、孟加拉国和斯里兰卡的全部版图)的茶，是1780年由英属东印度公司从中国引进茶籽，并派人赴中国学习种茶、制茶技术，聘请中国技术人员，然后在这一地区开始推广种植的。     

卫星数据给出的2005年巴基斯坦地震快照

尽管众所周知欧亚大陆与印度次大陆的碰撞形成了喜马拉雅，但对这些板块的实时空间地壳运动进行观测是困难的。不过，科学家能通过合成孔径雷达（SAR）这只太空眼目睹喜马拉雅形成的部分过程。

巴基斯坦蛇绿岩及铬铁矿分布

巴基斯坦的蛇绿岩分布在南巴基斯坦,是洋壳碎片,它仰冲在印度-巴基斯坦次大陆之上(贝拉、穆斯林巴格、若布、瓦齐里斯坦)或侵位在俯冲杂岩内(拉斯戈).在北巴基斯坦蛇绿岩与主要的逆冲断裂带在一起(尚格拉),或者与欧亚板块和印度-巴基斯坦次大陆之间的印度缝合线在一起(达加、布尔齐尔、德拉斯).铬铁矿主要产在穆斯林巴格、若布、瓦齐里斯坦、达加等蛇绿岩体内.
