crust, long-term storage of elements in weathering profiles, and petrogenesis of siliciclastic sediments.
Orthogneisses are of granitic, granodioritic
, quartzdioritic, and tonalitic composition.
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.
Finally, the middle crust is granodioritic
, the lower crust is felsic granulitic, and the mantle is peridotitic.
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.
Several granitic, granodioritic
, tonalitic, dioritic and syenitic intrusions close to the quartz veins and minor gold field soils were observed (Figures 12 and 13).
In this region most possibly the precipitation waters rich of [Co.sub.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).

The Corralitos area is underlain by hydrothermally-altered, coarse-grained granodioritic
to monzonitic intrusions and adjacent volcanic and volcaniclastic rocks of probable Cretaceous age.
