Age of the Jamaican Granodiorite
Geological Magazine, 1963AbstractGranodiorite intrusions in Jamaica were assigned by early workers to various ages from Pre-Cambrian to late Tertiary. Recent surveys have shown that the granodiorite intrudes Maestrichtian sediments and has provided material for pebbles in an Eocene conglomerate. Its age is therefore very late Cretaceous or very early Tertiary.

Pre‐Granodiorite dikes in granodiorite, Paradise Range, Nevada
Eos, Transactions American Geophysical Union, 1935In the course of the study of the deposits of magnesite and brucite in the Paradise Range by the Geological Survey In cooperation with the Nevada state Bureau of Mines, opportunity was afforded to map a part of a granodiorite stock and a swarm of dikes. Seven successive igneous intrusions, demonstrated by cross‐cutting relationships, occur in this area

Hydrothermal Alteration in Some Granodiorites
Clays and clay minerals (National Conference on Clays and Clay Minerals), 1957AbstractThe patterns of distribution of the mica and clay minerals resulting from alteration of feldspars are much less regular and well defined in the “porphyry copper” deposits than in the vein deposits such as those at Butte, Montana. There are, however, interpretative problems common to both.

„Der Granit war in den altesten Zeiten schon eine merkwurdige Steinart und ist es zu den unsrigen noch mehr geworden. Die Alten kannten ihn nicht unter diesem Namen. Sie nannten ihn Syenit, von Syene, einem Orte an den Grenzen von Athiopien. Die ungeheuren Massen dieses Steines flosten Gedanken zu ungeheuren Werken den Agyptiern ein.

Microanalysis of N.R.M. in a granodiorite intrusion
Earth and Planetary Science Letters, 1974The natural remanent magnetization (NRM) associated with individual oriented grains of the major rock-forming minerals of the Tatoosh granodiorite has been determined to establish the magnetic carriers of stable and unstable components of NRM. In addition, magnetic parameters such as weak field susceptibility, Konigsberger ratio, saturation isothermal ...

Hypersthene granodiorite in Virginia
Geological Society of America Bulletin, 1935Introduction The Blue Ridge-Catoctin anticlinorium extends for more than 300 miles across the State of Virginia, from the Potomac River to the North Carolina and Tennessee lines (Fig. 1). In northern and central Virginia it includes the Blue Ridge proper, which forms its northwestern border, and part of the Piedmont region of foothills, which lies ...

Strain analysis of a shear zone in a granodiorite
Tectonophysics, 1978Abstract A ductile shear zone in a late Precambrian granodiorite, from the Rouergue (southwest part of the French Massif Central) has been studied. A single episode of deformation is responsible for the formation of a foliation and a well-defined lineation which are localized into an elongated zone, a few decimeters wide. The strain features can be
