Cl can chemically be extracted from any kind of rock or mineral that contains at least one of these target elements, such as limestone, Ca-/K-feldspar or Ca-pyroxene.
We try to avoid rocks with high chlorine concentrations because of the complex Cl).
The LDEO Cosmogenic Nuclide Group develops terrestrial cosmogenic nuclide techniques and applies those as chronometers and tracers in the Earth Sciences.
Terrestrial cosmogenic nuclides are produced by interactions between secondary cosmic rays and near surface rocks.
We are a collaboration of researches from the Devision of Geochemistry.
We use tracers that are naturally present in the envronment, deliberately-injected and transient tracers to investigate earth science problems in the areas of oceanography, continental waters, paleoclimatology, geochronology, and geology.
Our research subjects include paleocllmate provenance studies, volcanoes and deep earth time.Hella is currently visiting at Lamont-Doherty Earth Observatory (LDEO) for the whole spring while Aleksi just got a glimpse of the work and life around the NYC.Travelling to a different country always broadens your mind.Our research interests cover a wide spectrum of earth scientific disciplines and include timing of ice ages, subglacial erosion rates, uplift rates of Pleistocene terraces, and a better understanding of the production systematics of cosmogenic nuclides. Many of these processes occur so rapidly and unexpectedly that they have daunting consequences.Many of these processes occur so rapidly and unexpectedly that they have daunting consequences.We are poorly equipped to predict their nature and possible impacts due to the lack of scientific understanding.* Glacier and climate history of southern South America, New Zealand, Antarctica, and eastern North America.earth’s surface and Earth Surface Processes (ESP) are cornerstones defining fundamental boundaries for civilization.In particular, the impact of current environmental change on the nature of Earth Surface Processes is hardly predictable.It is a high priority challenge for modern earth sciences to better understand such processes. The extraction and cleanup lines were designed by Nat Lifton (U. Arizona), both of who have consulted with Brent during construction.In 2008, the lab obtained adequate space and cooling capacity in the new Comer Geochemistry Building to handle our thermal load during the extraction process.Even though Norway and the USA seem similar in many aspects, dipping into a new scientific environment, not to mention the exciting life in this huge city, literally opens our minds.
