This thesis presents geological, petrological, geochemical, and
zircon U-Pb-Lu-Hf isotopic field data for representative
Precambrian lithologies in the Western Liaoning-Northeastern Hebei
Provinces along the northern margin of the North China Craton
(NCC). It describes late Neoarchean (2.64-2.48 Ga) supracrustal
metavolcanic rocks and granitoid gneisses; late Paleoproterozoic
(1.72-1.68 Ga) Jianping alkaline plutons and Pinggu alkaline
volcanic rocks; and newly discovered ~1.23 Ga mafic dykes. The
nature of magma sources and genesis of each magmatic episode are
investigated, and the Precambrian (~2.6-1.2 Ga) lithospheric mantle
evolution and crust-mantle interaction processes are established
for the first time -aspects that provide important constraints in
our understanding of the Precambrian crustal evolution and
geodynamic processes in the region studied.
