A NS trending Cenozoic fold-and-thrust belt has developed in the western part of the Hidaka Collision Zone (HCZ), central Hokkaido, Japan. A quantitative estimation of the late Cenozoic convergence rate at the front of the ...
OBSERVATION OF TWO 4-COORDINATED AL SITES IN MONTMORILLONITE USING HIGH MAGNETIC FIELD STRENGTH 27AL MQMAS NMR

Ohkubo T.; Ikeda Y.; Kanehashi K.; Saito K. (2003)

Analyses of the layer structure of Na-montmorillonite have been performed using 27Al MAS and 27Al MQMAS NMR techniques. Results of 27Al MAS NMR measurements at higher magnetic field strength (16.4 T) suggest that the ...
ORIGIN OF UREILITES INFERRED FROM A SIMS OXYGEN ISOTOPIC AND TRACE ELEMENT STUDY OF CLASTS IN THE DAR AL GANI 319 POLYMICT UREILITE

Kita N.T.; Togashi S.; Liu Y.; Morishita Y.; Ikeda Y.; Weisberg M.K. (2004)

Secondary ion mass spectrometer (SIMS) oxygen isotope analyses were performed on 24 clasts, representing 9 clast types, in the Dar al Gani (DaG) 319 polymict ureilite with precisions better than 1‰. Olivine-rich clasts ...
