The importance of this study is to identify the newly reordered and recognized basaltic intrusion for the first time in Maasser El Chouf in Lebanon. The recorded basaltic intrusion cut the Jurassic-Lower Cretaceous rock in this area. Necessary field inspection, geology, mineralogy and chemical tests were carried out on 8 basalt samples to determine their mineralogy, petrography and chemical composition. Representative samples have been tested with polarizing microscope, X-ray diffraction (XRD) and X-ray fluorescence (XRF). Petrographic and mineralogical studies show that the basalt is characterized by presence mainly of calcic-plagioclase feldspar, pyroxene-augite and olivine minerals. Secondary minerals of iron oxides also present (ilmenite and magnetite). The most appeared property is the alteration of olivine mineral to iddingsite that indicated highly weathered process. The composition of the basaltic samples reflects ultrabasic-basic type (Basanite-Tholeiitic basalt). The existence of volcanic activity occurred mostly with Pliocene age (< 2 Ma) as indicated by previous studies for similar basalt in Lebanon. Possibly, these boulders have been carried up from some deeper intrusive magmatic body under very active tension zones. Volcanism of Lebanon basalts belong to the alkaline olivine basalt, suite generally associated with tension, rifting and block faulting movements of the continental crust. Most of the volcanisms in Lebanon and in Harrat Ash Shaam Basalt from Syria and Palestine through Jordan to Saudi Arabia are related and connected to the opening of the Red Sea Rift System, making the area with tremendous volcanic tectonic activities.

Due to the mass demand for excellent construction materials for infrared and super structures in Jordan, intensive field and laboratory works were carried out to determine the quality of basalt as a source for construction uses or as aggregate materials. Representative basaltic samples were collected from four quarries in Harrat Ash Shaam Basalt (HASB), northeast Jordan (Al-Azraq, Tel-Hassan, Q’a-Khanna and Al-Aritayin). Necessary and accentual quality control tests were carried out on 17 samples of basalt to determine the physical and mechanical properties of target samples, whereas petrographic and chemical analysis for some representative samples have been carried out using a polarizing microscope and X-ray fluorescence (XRF). This study aims to focus on the main engineering characteristics of the basalt rocks and to shed some light on their properties. This work represents the results of petrographic and chemical analysis, tests of abrasion, absorption, specific gravity, unit weight and void ratio, sieve analysis (gradation), soundness, flakiness and elongation indices, pulse velocity and compressive strength. Petrographic studies show that the basalt is characterized by a presence mainly of calcic-plagioclase feldspar, pyroxene-augite and olivine. The composition of the basaltic samples reflects ultrabasic-basic (Basanite-Tholeiitic basalt type). The basalt is characterized by higher specific gravity, lower absorption and medium abrasion loss values, and resistance to corrosion, with medium to high compressive strength. The results of the studied physical and mechanical properties of the basalt that have been tested comply with the standard requirements. In most of the studies, basalt has good physical and mechanical properties that can be used for engineering applications.

Surface water quality is largely influenced by both natural processes and anthropogenic inputs. This study involves the characterization of the concentration of heavy metals of Cd, Cr, Cu, Fe, Mn, Ni, Pb, and Zn, and the sources of pollution in water and sediment of the Upper Litani River Basin (ULRB) in Lebanon. The investigation was performed during three seasons of rainy, mid-rainy spring and wet periods for two years during different flow rates. Sediments were characterized by a set of chemical analyses, cation exchange capacity (CEC), mineralogy of the sediments, X-ray diffraction (XRD), and Fourier transformed infrared spectroscopy (FTIR). To assess metal contamination in sediment, Consensus-Based Sediment Quality Guidelines of Wisconsin (CBSQG) were applied. The metals contamination in the sediments was also evaluated by contamination factor (Cf). The test results showed that the effect of seasonal variations was significant in the Upper Litani River Basin. Principal Compound Analysis (PCA) and Pearson’s correlation were also performed in this study to compare and determine the correlation between metals in water and sediments. The concentrations of Pb, Cd, Cu, Cr and Zn in all sediment samples are above the norms in winter, while Fe was increased in summer. The results showed that the importance of monitoring of changes of heavy metals values and physico-chemical characterization of different parameters could represent the possibility of a comprehensive assessment of negative pressures on the water and soil ecosystem of Litani River Basin during different seasons.

Open Journal of Geology 2016年第9期6卷 1137-1148页

作者： khaled Al tarawneh Civil Department Faculty of Engineering Isra University Amman Jordan

Jordan’s mining sector is considered the cornerstone to the Jordanian economy. It plays a vital role in growth of many other important sectors in the economy and contributes to the Jordan’s standard of living. The mining industry in Jordan is dominated by the production of phosphate, potash, building and decoration stones, glass sand and other nonmetallic resources. Recently, Jordan has been ranked as the sixth largest producer and the second largest exporter of phosphate, the fourth largest producer and the second largest exporter of potash, and has the 5th largest oil-shale reserves in the world. Also, Jordan has sustainable amounts of uranium around 3% of the world resources. The main objective of this research is to focus on the present status of mining industry in Jordan with the aim to emphasis the most important industries, and its effect on the economy of Jordan in order to generate new wealth depends on its mineral endowment. A literature review has been carried out by reviewing the most published articles and the publicly available reports published by various Jordanian Institutions as well as from the private sector. The author reveals that there are many positive outlooks which are looming with an increasing domestic added value along with investing in other areas, such as feldspar, clays, travertine, gypsum, zirconium, uranium, copper and rare earth elements (REE). This requires activating the exploitation of many other untapped mineral resources in the country to achieve a progress that works for meeting the global great demands worldwide. In this context, successive governments have put effort into policies that promote and facilitate investment in the mining sector in Jordan. A comprehensive outlook of the mining sector in Jordan has been discussed in this article. The author also highlighted the opportunities and threats in this sector and more important dilemmas focused on what needs to be carried out by the Jordanian government, including importan

A semi-precious stone is known as a gem or gemstone (also a jewel, a gem, a precious stone), which is a portion of mineral in refined and cut form that could be used to create a jewelry or other embellishments. A gem also can be defined as any mineral that is highly prized for its beauty, durability, and rarity, is used for personal adornment and has been enhanced in some manner by altering its shape usually by cutting and polishing. Semi-precious stones occurred as xenolithes are widespread in Jordan within different source of rocks. High grade of copper as malachite and chrysocolla and plancheite?is?suitable for gemstone manufacture found in Finan area. High purity of garnet can be found in metamorphic rocks in Wadi Araba area, whereas xenoliths of pyroxene, olivine and spinel-perioditite and garnet are wide spread in basalt and pyroclastic materials in northeast Jordan. The studied semi-precious stones are part of the Miocene alkali basaltic rocks?that covered the northeastern part of Jordan within Harrat Al-Shaam?Basaltic Super Group Plateau concentrated mainly in volcanic centers and volcaniclastic materials of Aritian, Hassan, Ufiyahim?and Bishriyya formations. Some of these xenoliths and xenocrysts can be considered as semi-precious stones. This study is focused on characterization of petrography, mineralogy and geochemistry of these semi-precious stones like olivine, pyroxene and garnet xenoliths that have been collected from selected areas in northeast Jordan. The samples were analyzed by polarizing microscope, X-Ray Diffraction (XRD), X-Ray Fluorescence (XRF) and Scanning Electron Microscope (SEM). Cutting and polishing tests have shown that some of the studied xenoliths are suitable for manufacturing attractively colored gemstones and could be considered as semi-precious stones. The geological chances for the discovery of some hundreds of tons of these?gemstone-raw materials are considered to be good in volcaniclastic materials that are associated within

Characterization and Origin of the Miocene Mudawwara-Quwayra Basaltic Dike, Southern Jordan

引用

International Journal of Geosciences 2015年第8期6卷 869-881页

作者： Hani Alnawafleh khaled tarawneh Khalil Ibrahim Khitam Zghoul Awad Titi Rami Rawashdeh khaled Moumani Ahmad Masri Faculty of Engineering Al-Hussein Bin Talal University Ma’an Jordan Faculty of Engineering Tafila Technical University Tafila Jordan Faculty of Natural Resources and Environment Hashemite University Zarqa Jordan Geological Mapping Division Geology Directorate Natural Resources Authority Amman Jordan

Petrographic, mineralogical and geochemical investigations were carried out on representative?samples from the Mudawwara-Quwayra Dike (MQD) in southernJordan. The MQD intruded Paleozoic and Cretaceous rocks as sub-vertical basaltic plugs, striking NW-SE along a fault zone and extending for more than 100 km. The MQD forms irregularly positive features, and is represented by symmetrical, elliptical, elongated or circular hills. It comprises thin basaltic layers intercalated?with pyroclastics and inclusions of different size and lithology, including limestone, sandstone, phosphate, quartzite, and marble. Petrographically, the rock exhibits phyric, porphyritic, vitrophyric and locally glomerophyritic textures manifested by plagioclase, clinopyroxene and rare?olivine and set in a matrix of plagioclase, pyroxene, brown glass and opaque phases. Clinopyroxene?and olivine phenocyrsts show disequilibrium textures such as reaction/resorbed rims in the?forms of corroded ends. The paragenetic sequence shows that olivine is the first phase to be crystallized and coexisting with pyroxene at sometime, while pyroxene continues crystallization. Plagioclase might have crystallized in contemporaneous later than the pyroxene. The MQD rocks are classified?as basalt and exhibit a narrow range of silica with a unique subalkaline affinity. This is most?probably attributed to assimilation of the abundant siliciclastic inclusions by the ascending magma. Emplacement of the MQD is attributed to regional phase of magmatism in Jordan and Saudi Arabia, which is probably the peripheral extension of a large magmatic event widely exposed in the Red Sea realm.

Social distancing during COVID-19 has become one of the most important measures in reducing the risks of the spread of the virus. Implementing thesemeasures at universities is crucial and directly related to the physical attendance ofthe populations of students, professors, employees, and other members on campus. This research proposes an automated scheduling approach that can help universities and schools comply with the social distancing regulations by providingassistance in avoiding huge assemblages of people. Furthermore, this paper proposes a novel course timetable-scheduling scheme based on four main ***, a distance of two meters must be maintained between each student inside theclassroom. Second, no classrooms should contain more than 20% of their regularcapacity. Third, there would be no back-to-back classes. Lastly, no lectures shouldbe held simultaneously in adjacent classrooms. The proposed approach wasimplemented using a variable neighborhood search (VNS) approach with an adaptive neighborhood structure (AD-NS) to resolve the problem of scheduling coursetimetables at Al-Ahlyyia Amman University. However, the experimental resultsshow that the proposed techniques outperformed the standard VNS tested on university course timetabling benchmark dataset ITC2007-Track3. Meanwhile, theapproach was tested using datasets collected from the faculty of information technology at Al-Ahlyyia Amman University (Jordan). Where the results showed that,the proposed technique could help educational institutes to resume their regularoperations while complying with the social distancing guidelines.
