Synthesis of Poly(amide-sulfide)s by Polyaddition of Dithiols to N,N′-Methylenebisacrylamide

1986 Values for Fifteen GSJ Rock Reference Samples, “Igneous Rock Series”

“…The Geological Survey of Japan (GSJ) had issued two rock reference samples, Granodiorite JG-1 and Basalt JB-1 in 1967 and 1968 (1)(2). In a series of papers (3)(4)(5)(6)(7)(9)(10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27), results and reports have been published on these two samples concerning their chemical and isotopic compositions, their geological ages and physical constants. However, the supply of these samples was exhausted in 1981, after settlement of 75 analytical components.…”
