A 200 KYR RECORD OF COSMOGENIC RADIONUCLIDE PRODUCTION RATE AND GEOMAGNETIC FIELD INTENSITY FROM 10BE IN GLOBALLY STACKED DEEP-SEA SEDIMENTS

Frank M.; Schwarz B.; Baumann S.; Kubik P.W.; Suter M.; Mangini A. (1997)

The reconstruction of geomagnetic field intensity variations during the last 200 kyr from paleomagnetic data is at present the subject of numerous studies and major debate. There is currently no generally accepted record. ...
CORRECTION OF IN SITU COSMOGENIC NUCLIDE PRODUCTION RATES FOR GEOMAGNETIC FIELD INTENSITY VARIATIONS DURING THE PAST 800,000 YEARS

Masarik J.; Frank M.; Schafer J.M.; Wieler R. (2001)

We present integrated relative production rates for cosmogenic nuclides in rock surfaces, which take into account reported variations of the geomagnetic field intensity during the past 800,000 yr. The calculations are based ...
LEAD ISOTOPES IN NORTH PACIFIC DEEP WATER - IMPLICATIONS FOR PAST CHANGES IN INPUT SOURCES AND CIRCULATION PATTERNS

van de Flierdt T.; Frank M.; Halliday A.N.; Hein J.R.; Hattendorf B.; Günther D.; Kubik P.W. (2003)

The sources of non-anthropogenic Pb in seawater have been the subject of debate. Here we present Pb isotope time-series that indicate that the non-anthropogenic Pb budget of the northernmost Pacific Ocean has been governed ...
NEW CONSTRAINTS ON THE SOURCES AND BEHAVIOR OF NEODYMIUM AND HAFNIUM IN SEAWATER FROM PACIFIC OCEAN FERROMANGANESE CRUSTS

van de Flierdt T.; Frank M.; Lee D.C.; Halliday A.N.; Reynolds B.C.; Hein J.R. (2004)

The behavior of dissolved Hf in the marine environment is not well understood due to the lack of direct seawater measurements of Hf isotopes and the limited number of Hf isotope time-series obtained from ferromanganese ...
THALLIUM ISOTOPE VARIATIONS IN SEAWATER AND HYDROGENETIC, DIAGENETIC, AND HYDROTHERMAL FERROMANGANESE DEPOSITS

Rehkamper M.; Frank M.; Hein J.R.; Porcelli D.; Halliday A.; Ingri J.; Liebetrau V. (2002)

Results are presented for the first in-depth investigation of Tl isotope variations in marine materials. The Tl isotopic measurements were conducted by multiple collector-inductively coupled plasma mass spectrometry for a ...
THE HF ISOTOPE COMPOSITION OF GLOBAL SEAWATER AND THE EVOLUTION OF HF ISOTOPES IN THE DEEP PACIFIC OCEAN FROM FE-MN CRUSTS

David K.; Frank M.; O'Nions R.K.; Belshaw N.S.; Arden J.W. (2001)

This paper presents a revised chemical purification method of Hf for the measurement of Hf isotope ratios of Fe-Mn crusts on a new generation of double focusing multiple collector plasma source mass spectrometer (MC-ICP-MS).By ...
