Linear alkali correlation in oceanic alkali basalts

The carbon dioxide solubility in alkali basalts: an experimental study

Experiments were conducted to determine CO2 solubilities in alkali basalts from Vesuvius, Etna and Stromboli. The basaltic melts were equilibrated with nearly pure CO2 at 1200°C under oxidizing conditions, and at pressures ranging from 269 to 2060 bars. CO2 solubility was determined by FTIR measurements. The results show that alkalis have a strong effect on the CO2 solubility and confirm and re...

Alkali basalts and enclosed ultramafic xenoliths near Ushuaia, Tierra Del Fuego, Argentina

At the southernmost part of Tierra del Fuego a few outcrops and erratic boulders of alkali basaltic rocks with ultramafic enclaves have been studied. Alkali basalt plugs or pipes hitherto identified are scarce, and host rocks are constituted by slates that belong to Mesozoic deposition. The petrography, texture and composition of the basalt and xenoliths were investigated by petrographic micros...

Petrochemical Characteristics of Neogene and Quaternary Alkali Olivine Basalts from the Western Margin of the Lut Block, Eastern Iran

The Nayband strike-slip fault forms the western margin of the micro-continental Lut block in Eastern Iran. Neogene and Quaternary mafic volcanic rocks collected near Tabas, along the northern part of the fault (NNF; 15 Ma), and further to the south, along the middle part of the fault (MNF; 2 Ma), are within-plate sodic-series alkali olivine basalts with high TiO2 and up to >16% normative nephel...

Milk alkali syndrome.

The milk alkali syndrome was more commonly seen when milk and absorbable alkalis were the mainstays of treatment of symptoms due to acidrelated upper gastro-intestinal disease. The syndrome became rarer after the introduction of the non-absorbable alkalis and H2 receptor antagonists but it did not disappear altogether and should always be suspected when patients present with hypercalcaemia, ren...
