To interpret the provenance 0f Injana Formation, 20 sandstone samples of Formation were collected from Zawita and Dekala areas north Iraq (10 for each sections ), then thin section have been done sildes. The petrographic study showed that sedimentary, metamorphic igneous rock fragments, quartz (mono&polycrystalline) feldspars (microcline, orthoclase plagioclase) make up main grain component...

The Benue Trough Basin (BTB) of Nigeria is geologically and geo-morphologically subdivided into upper, middle, lower segments. BTB the subject geological research due to its rich coal deposits that have potential for oil gas. purpose present study examine origins, depositional environments, thermal history selected coals processes influence their quality. Coal samples from different open cast m...

Abstract Variable single and/or swarms of post-granitic dikes are widespread at Gabal Serbal, Southwestern Sinai, Egypt. The present article aims to identify and discriminate these multiphase through detailed geological, petrographical, geochemical examinations. These classified into two subphases: (1) acidic (porphyritic dacite, microgranite, granophyre, alkaline granophyre dikes); (2) basic (...

Exposed in large, continuous outcrops Provence, southern France, the Castellas fault formed as a normal Upper Cretaceous and was reactivated left-lateral Eocene. Structural, petrographical, isotopic, geochronological analyses shed light on sequence of deformational-diagenetic stages zone help identify properties that controlled fluid-flow behavior through time. Abrupt contrasts fracture abundan...

this is a descriptive field study. the aim of this study was to find personal, familial and socio-economical characteristics of children under five years old, and relationships between these characteristics with acute respiratory infection. the sample was 60 children with acute respiratory infection. data gathered by a questionair include 44 question about personal, familial and socio-economica...

chemical and morphological characterization of different parts of banana plant(musa paradisica) (peduncle, leaf stalk and pseudo stem) were carried out in orderto assess their potentiality for chemical pulp. each portion was tested forextractives, sodium hydroxide solubility, ash, lignin, cellulose and pentosancontents as well as their fiber length and width. these segmented parts werecharacter...

Many studies have shown that women are under-represented in tenured ranks in the sciences. We evaluate whether gender differences in the likelihood of obtaining a tenure track job, promotion to tenure, and promotion to full professor explain these facts using the 1973-2001 Survey of Doctorate Recipients. We find that women are less likely to take tenure track positions in science, but the gende...

In the Tethyan realm, leucocratic rocks were recognized as dikes and layers outcropping in ophiolitic of Western Alps, Corsica, Northern Apennines. Several authors have suggested that origin is associated with partial melting cumulate gabbro. Major trace elements composition paragenesis provided information about genetic processes. This research aims at disclosing, for first time, petrographica...
