The present study aimed to evaluate the ability of a mixture gabbro powder and dacite promote plant growth, provide nutrients alter soil chemical characteristics. Two experiments were conducted under different field conditions, in which black oat beans added with increasing doses (0 10 t ha-1) rock blend. grain yield (beans), dry matter production (oats) nutritional status crops evaluated. At e...

In the Geologists and Miller Ranges of the central Transantarctic Mountains, mafic and ultramalic tectonic blocks occur in an Early Cambrian amphiboliteto granulite-facies lower crustal transpressional shear zone. Mafic blocks consist of garnet + clinopyroxene symplectite + hornblende + plagioclase + quartz + ilmenite f orthopyroxene f biotite;mineral compositions in these blocks generally refl...

The iron-titanium oxide minerals of three troctolites from the Freetown layered gabbro have been analysed using an electron microprobe. Comparisons of the analyses of the iron-titanium minerals with the data of Buddington and Lindsley (I964) provide temperature and oxygen fugacity information relating to particular magnetite-ilmenite grains. Magnetite-ilmenite grains occurring in different sili...
