On the Hitokabe granodioritic mass, Kitakami mountainland

open access: yesThe Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1969
The Hitokabe granodioritic mass intruded into Paleozoic sediments and ultrabasic rocks in the Kitakami mountainland is studied petrochemically. The results of the modal analyses show that this mass is mainly composed of the granodiorite and subordinately quartz diorite, and inner facies of the mass are more basic than the outer facies.

Pegmatite Production by Geochemical Fractionation of a Granodiorite Pluton

open access: yes, 2016
Plutons are igneous systems in which magma crystallizes within the crust and does not erupt. Minerals record the chemistry of the magma as they crystallize and they change the composition of the residual liquid in a predictable way as the magma body ...

1.90-1.88Ga arc magmatism of central Fennoscandia: geochemistry, U-Pb geochronology, Sm-Nd and Lu-Hf isotope systematics of plutonic-volcanic rocks from southern Finland

open access: yesGeologica Acta, 2016
The earliest Svecofennian magmatism in southern Finland has been dated at 1.90-1.88Ga. As an example of this, the Orijärvi (ca. 1.89Ga) and Enklinge (ca.

Temperature dependence of mechanical properties and damage evolution of hot dry rocks under rapid cooling

open access: yesJournal of Rock Mechanics and Geotechnical Engineering
Understanding the differences in mechanical properties and damage characteristics of granitoid under high temperatures is crucial for exploring deep geothermal resources. This study analyzes the evolution of the acoustic emission (AE) characteristics and

COMPARATIVE ANALYSES OF PETROGRAPHIC AND PHYSICOMECHANICAL PROPERTIES OF SELECTED GNEISSES FROM OKENE, SW BASEMENT COMPLEX, NIGERIA

open access: yesAcademy Journal of Science and Engineering
In an attempt to determine the more suitable gneiss for foundation works (house, road, and dam construction), the need arises to search for geomaterials that will help to minimize the cost of executing durable engineering projects.

CHIME dating of monazite from pelitic hornfels of the Kurihashi Granodiorite, Kitakami Mountains

open access: yes
The Cretaceous Kurihashi Granodiorite in the Kitakami Mountains contains no monazite grain. To date the emplacement time of the Kurihashi Granodiorite by the CHIME method, monazite in a hornfels from the immediate contact of the granodiorite, instead ...
