Isotopic Ages of the Penglai Group in the Jiaobei Belt and Their Geotectonic Implications1
Autor: Xu Jiawei, Zhu Guang, W.R. Fitches, C.J.N. Fletcher
Publikováno v: Acta Geologica Sinica - English Edition. 7:417-433
The Penglai Group in the Jiaobei Belt is the only remaining cover of the Archaean to Early Proterozoic crystalline basement in eastern Shandong. The ages of deposition of the Penglai Group and of its deformation and metamorphism have long been a subj

Is the Ogcheon metamorphic belt of Korea the eastward continuation of the Nanhua Basin of China?
Autor: Guang Zhu, W.R. Fitches
Publikováno v: Gondwana Research. 9:68-84
The Ogcheon metamorphic belt in central Korea has been interpreted to be the eastward extension of the Nanhua Basin (aulacogen) of southeast China. In this paper, comparisons are made between the two regions based on stratigraphic, thermal-tectonic a

Geological and isotopic constraints on the timing of movement in the Tan-Lu Fault Zone, northeastern China
Autor: W.R. Fitches, C.J.N. Fletcher, J.A. Evans, C.C Rundle
Publikováno v: Journal of Southeast Asian Earth Sciences. 11:15-22
The Tan-Lu Fault Zone forms part of a major fault system which can be traced for over 5000 km parallel to the present Asian continental margin. A sinistral displacement of about 700 km has been postulated on the zone, and it has been argued that this

Isotopic constraints on the Palaeozoic evolution of the Shandong Peninsula, N.E. China
Autor: C.J.N. Fletcher, Guang Zhu, C.R. Rundle, Jiawei Xu, J.A. Evans, W.R. Fitches
Publikováno v: Journal of Southeast Asian Earth Sciences. 9:241-248
The Ponglai Group, exposed in the Shandong Peninsula of N.E. China, is a low-grade metasedimentary cover to high-grade Archaean-Mid Proterozoic basement. The age of deposition of the Ponglai Group and of its tectono-thermal evolution have been the su

Transected folds from the western part of the Bala lineament, Wales
Autor: W.R. Fitches, W.T. Pratt
Publikováno v: Journal of Structural Geology. 15:55-68
Fold-cleavage relationships are described in the Cadair Idris area of the Lower Palaeozoic Welsh Basin, which includes the western part of the Bala Lineament. Many fold hinges are transected by the broadly contemporaneous Caledonian (Lower Devonian)

Chlorite-mica stacks in low-strain rocks from central Wales
Autor: J. Craig, A. J. Maltman, W.R. Fitches
Publikováno v: Geological Magazine. 119:243-256
SummaryWeakly deformed, low grade, Lower Palaeozoic metasediments from central Wales contain abundant stack-like intergrowths of chlorite and white mica that closely resemble stacks described from the Devonian Hunsruckschiefer of West Germany; the Or

Early veins as evidence of detachment in the Lower Palaeozoic rocks of the Welsh Basin
Autor: J. Craig, R. Cave, Alex J. Maltman, W.R. Fitches
Publikováno v: Journal of Structural Geology. 8:607-620
A suite of small-scale structures, mostly represented by veins, is widely developed in the Lower Palaeozoic elastic sedimentary rocks of the Welsh Basin. The structures were produced after considerable dewatering and diagenesis had taken place, but b

Late pan-african syenite-granite plutons in NW nigeria
Autor: I.G. Egbuniwe, M. Bentley, W.R. Fitches, N.J. Snelling
Publikováno v: Journal of African Earth Sciences (1983). 3:427-435
The Pan-African (800–500 Ma) Older Granite suite of Nigeria is dominated by calc-alkaline, I-type magmatism and is a product of subduction processes at the eastern margin of the West African craton. The Kanoma and Sabon Gida composite plutons of NW

A plutonic diorite complex in the north of the Fiskenæsset region
Autor: W.R Fitches
Publikováno v: Rapport Grønlands Geologiske Undersøgelse. 73:72-80
A thick diorite-monzodiorite sheet over 2 km in length and up to 600 m in width (fig. 35) is exposed at 50°25'E and 63°55'N, about 7 km south of Qeqertaussaq by Kangerdluarssûngûp taserssua. Several diorite dykes, some over 10 m in thickness, tie
