Different rock types (syenogranite, alkali feldspar granite and quartz syenite intruded by microgranite dikes veins) were investigated in the Nikeiba region Egypt. The main components of studied intrusive rocks, comprised granites syenite, are plagioclase, amphibole, biotite, K-feldspar different proportions. Ground gamma ray measurements show that syenogranite, have highest radioactivity (K, e...

The study of the O and C isotope composition calcite from nepheline syenites, ijolites carbonatites Chik intrusion intrusions Erzin–Tarbagatay group Sangilen (Eastern Siberia, Russia) showed derivation alkaline melts enriched with a carbonate component host marbleized sedimentary rocks. calculations that about 40% initial mass carbonates involved in interaction silicate have remained after deca...

The article is focused on the assessment of impact mining waste environment. Mining (MW) understood as mine (mining) dumps and processing plants (tailings dumps). also suggests considering MW technogenic deposits rare earth precious metals, development which will allow solving many environmental, social economic problems using natural resources in a sustainable manner. objects under study are l...

Syenites are relatively rare within the Nigerian Basement Complex. As a result of their rarity, these rocks have been given less research attention over time and consequently poorly understood. The syenitic at Igarra were studied to ascertain tectonic evolution using geochemistry. Sampling was carried out survey-type geological field mapping approach. A total 10 samples collected for laboratory...
