hired is a large gold prospecting area which is located in south khorasan province, in the east of iran. gold mineralization is found in 4 target areas covering about 24 km2. the host rocks are mainly tertiary volcanics, some jurassic and cretaceous sediments. sub-volcanic rocks are of magnetite series (gabbros to diorite) and ilmenite series (granite-granodiorite-monzonite) which have intruded...

The Upper Kitsault River area lies approximately 23 to 30 km north of Alice Arm, in the Skeena Mining Division, British Columbia. Mineral occurrences are of three principal types: copper and gold-rich quartz-chlorite stockwork deposits, silver-rich quartz-sulphate-carbonate deposits; and molybdenum-rich quartz stockwork deposits (Alldrick et al., 1987). The first two types are hosted by lower J...

the arghash area is located 45 km to southwest of neyshabour. the subvolcanic rocks in the area consist of biotite hornblende quartz monzodiorite porphyry, hornblende biotite quartz monzodiorite porphyry, hornblende monzonite porphyry, biotite hornblende monzonite porphyry, monzodiorite porphyry and biotite quartz monzodiorite porphyry units. the volcanic rocks consist of hornblende biotite dac...

A megacrystal granodiorite, occurring in a pluton in the Monterey peninsula of California, is gradational south to quartz monzonite and then to tonalite and trondhjemite and southeast to granodiorite and then to tonalite. A primary magmatic origin for the pluton is indicated by normally zoned plagioclase crystals and by dikes that extend into biotite-hornblende quartz diorite southeast of Point...

Texada Island (Figure 2-5-1) is with.in Wrangellia. Calcalkaline plutonism of the Coast plutonic complex is superimposed on this terrane. The northern part of the island is made up mainly ct basaltic amygdaloidal flows and pillovr lavas of the ?exad1 Formation (Karmutsen Fbrmation) overlain by massibe grqi limestone and white marble of the Marble Bay Fonnatio I (Quatsino Formation). These Upper...
