Nyquist L.; Bogard D.; Yamaguchi A.; Shih C.Y.; Karouji Y.; Ebihara M.; Reese Y.; Garrison D.; McKay G.; Takeda H. (2006)Low concentrations of Th and Fe in the Yamato (Y)-86032 bulk meteorite support earlier suggestions that Y-86032 comes from a region of the moon far distant from the Procellarum KREEP Terrain (PKT), probably from the lunar ...

Yamaguchi A.; Sekine T. (2000)Shock recovery experiments of plagioclase feldspar in contact with pyroxene, shock-loaded at 36-53 GPa, showed that monomineralic glass of plagioclase was mixed with brecciated pyroxenes with virtual absence of mixed-mineral ...

Yamaguchi A.; Taylor G.J.; Keil K.; Floss C.; Crozaz G.; Nyquist L.E.; Bogard D.D.; Garrison D.H.; Reese Y.D.; Wiesmann H.; Shih C.Y. (2001)We performed petrologic, radiometric (Ar-Ar, Sm-Nd, and Mn-Cr ages), and ion microprobe studies of the basaltic eucrite, EET90020. This is one of the few rare basaltic eucrites whose 39Ar-40Ar age has not been reset during ...

Misawa K.; Yamaguchi A.; Kaiden H. (2005)We have undertaken petrologic and SHRIMP U-Th-Pb isotopic studies on zircons from basaltic eucrites (Yamato [Y]-75011, Y-792510, Asuka [A]-881388, A-881467 and Padvarninkai) with different thermal and shock histories. ...
