This outcrop is unusually rich in magnesium-iron carbonate minerals
, a discovery made in 2010, researchers said.
While Comanche's carbonate minerals
were originally attributed to hydrothermal activity, the team's new analysis points to a different origin.
Raman spectroscopy provides a technique for rapid identification of carbonate minerals
and provides additional relevant information that facilitates interpretation of these rocks.
Meanwhile, Southam's UWO research group is studying the role of microbes in fixing CO2 and precipitating carbonate minerals
, in particular as sedimentary rock.
0 mm) carbonate minerals
are frequently surrounded by finer (<1.
Funded by the Engineering and Physical Sciences Research Council and the Natural Environment Research Council, the team analysed the geochemistry of the site in order to assess its potential to capture and store carbon as carbonate minerals
That is to say, the most probable mechanism of scale inhibition in carbonate formation is the precipitation mechanism, due to the in-situ generation of calcium ions as the acidic low pH inhibitor slug is injected down hole during "squeeze" treatment, which causes the dissolution of carbonate minerals
such as calcite to generate calcium and other divalent cat ions.
Finding only trace amounts of carbonate minerals
on Mars isn't the only strike against the hypothesis that most of the Red Planet was once wet and warm (see p.
If warm oceans had once washed over Mars they should have left large deposits of carbonate minerals
such as the limestone rocks on Earth.
Little carbonate would be available in the altered rhyolitic host rocks to fix copper in carbonate minerals
at the surface (most of the surface copper was in chrysocolla).
Acid treatment of the oil shale material would digest the carbonate minerals
and yield in a concentrate of combustible matter.
The province draws millions of Turkish and foreign tourists each year with its unique destinations such as Pamukkale which contains hot springs and travertines, terraces of carbonate minerals
left by the flowing water, as well as ruins of ancient cities of Hierapolis, Laodicea and Phrygia.
