Thermal alteration of kerogen as an indicator of contact metamorphism to sedimentary rocks; 1H-NMR T1 and elemental composition
Geochemical Journal, Vol. 18, No. 3, P. 163-166, 1984
ABSTRACT
Kerogen in sedimentary rocks metamorphosed by an igneous dyke intrusion was studied by 1H-NMR and elemental analyses. The spin-lattice relaxation time (T1) of kerogen in 1H-NMR increases toward the contact of the dyke, and atomic ratios in H/C, N/C and O/C of kerogen decrease in the dyke proximity. 1H-NMR T1 of kerogen is a useful parameter for contact metamorphism.- Published : 1984-06-20
