Finally, the middle crust is granodioritic
, the lower crust is felsic granulitic, and the mantle is peridotitic.
As illustrated in Figure 7, the analyses from the Skye Mountain Road pluton (data from Horton 1994) are similar to those from the other granitic and granodioritic
plutons, consistent with the interpretation that it is the same ca.
The Cienaga Marbles were affected by emplacement of granodioritic
rocks belonging to the Santa Martha Batholith, developing a skarntype mineralogy as suggested by Castellanos and co-workers (personal communication), which gives rise to thin reaction zones.
Near the eastern basement outcrop the granite has quite a range of the minor intrusions: 15 to 60 cm thick dykes of quartz-biotite (with or without hornblende) monzonite; strongly porphyritic hornblende granodioritic
dykes with up to 1 cm long plagioclase phenocrysts in a fine- grained dark matrix; and thin leucogranite dykes similar to those displayed in Figure 3.
2] have penetrated into depths through deep faults (especially Naein--Darouneh) and other minor faults and meanwhile increasing the temperature and escalating the geothermal gradient as well as the heat resulting from the magma activities younger than Cretaceous that has caused formation of Soheyl granite to granodioritic
plutonic mass, the evidences of metamorphism of which resulting from its penetration inside the Ophiolitic melange of northern Naein can be observed, a series of reactions have occurred under 150[degrees]C temperature causing alteration of the Ultramafic rocks and heightening its Mg and other elements' content.
The volcanic rocks exposed in this area belong to the Sinjrani Volcanic Group having extensive intrusions of granodioritic
and granitic rocks (Shah, 1960).
Tripathi JK, Rajamani V (2007) Geochemistry and origin of ferruginous nodules in weathered granodioritic
gneisses, Mysore Plateau, Southern India.
The mafic volcanic units of the Aurora Group are intruded by numerous porphyritic felsic dykes and dioritic magnetic dykes and by the synvolcanic granodioritic
The Corralitos area is underlain by hydrothermally-altered, coarse-grained granodioritic
to monzonitic intrusions and adjacent volcanic and volcaniclastic rocks of probable Cretaceous age.
This rock unit is characterised by grey foliated Biotite acid/Biotite Hornblende quartz feldspathic gneiss of tonalitic to granodioritic
composition ;Mafic to ultramafic component which outcrops as discontinuous boudinaged lenses or concordant sheet of amplibolites with minor amount of biotite-rich ultramafite; and Felsic component, a varied group comprised of pegmatite, aplite quartz-oligoclase veins, fine-grained granite gneiss, and porphyritic granite.
Current interpretation of these encouraging results indicates at least four mineralised zones within an intrusive body of granodioritic
to dioritic composition, a sheared ultramafic unit (9m @ 1.
This local name was given to unusual textured magmatic rocks of largely dioritic and granodioritic
composition occurred in area of the Marktredwitz.
