| It is dominated by variably foliated, medium-grained, even-textured to porphyritic biotite hornblende tonalite and quartz diorite. |
|
| Small intrusions of mafic diorite and large intrusions of granophyric diorite cut the bedded sequence. |
|
| Partly granitized formations also occur in Terego County, which include porphyroblastic gneisses and quartz diorite. |
|
| At this location, a succession of chloritized volcaniclastic sedimentary rocks are over-thrust by a massive undeformed quartz diorite. |
|
| Permian and Triassic plutonic complexes comprise monzonite, granite, granodiorite or tonalite with minor gabbro and diorite. |
|
| Among the 30 different types of stone recognized are varieties of diorite, granite, bedded tuff, sandstones, limestones, and tufa. |
|
| If the magma is about 60 percent plagioclase feldspar and 35 percent mafic minerals, the intrusive rock diorite or the extrusive rock andesite will be formed. |
|
| The northwestern parts of La Hague comprise a suite of igneous units ranging in composition from diorite to granite monzonite collectively termed the Northern Granites. |
|
| The JQS prospect to the south is underlain by volcanic agglomerates which have been intruded by diorite dikes and stocks. |
|
| This area was the source of anorthosite gneiss and the gabbro or diorite gneiss from which many royal statues were carved. |
|
| The pits intersected the Chimu formation and bottomed in strongly altered diorite intruding the overlying quartzites. |
|
| The most common rock types in plutons are granite, granodiorite, tonalite, monzonite, and quartz diorite. |
|
| With an increase in calcic plagioclase and mafic minerals the rock type becomes a diorite. |
|
| Above the Bleng are large areas of diorite, while around Buckbarrow there are outcrops of the andesite Birker Fell Formation. |
|
| From 495m to end of hole at 500m a weakly altered and mineralized, late plagioclase hornblende diorite porphyry was intersected. |
|
| When the magma solidifies within the earth's crust, it cools slowly forming coarse textured rocks, such as granite, gabbro, or diorite. |
|
| Mineralization at Dreadnaught occurs within two zones of albitized, stockworked and sulphidized diorite hosted within amphibolite grade basalts. |
|
| The pavements on Queen Street are composed of the rock diorite and exhibit feldspar crystals, while those around Princesshay are composed of granodiorite. |
|
| From 88m to the current depth of 493m potassic altered and argillic overprinted, mineralized polymict breccia, diorite porphyry and diorite breccia was intersected. |
|
| Within the deeper diorite unit, some intense sericite alteration was observed with arsenopyrite, pyrite and pyrrhotite, generally as selvedges to quartz veins. |
|
|
|
| By contrast, more mafic rocks, such as tonalite, gabbro and diorite, have 1 to 5 ppm uranium, and limestones and sedimentary rocks usually have equally low amounts. |
|
| Gold mineralization occurs within quartz-pyrite veins occupying shear and dilatant structures within a 4 km diameter subcircular quartz diorite intrusion. |
|
| Seven diamond drill holes targeting zones of sub-cropping stockwork copper-gold mineralisation were completed at the Diorite Hill prospect. |
