Plutonic definition: noting or pertaining to a class of igneous rocks that have solidified far below the earth's surface.. See examples of PLUTONIC used in a sentence.
Machine learning-based prediction of trace element concentrations using data from the Karoo large igneous province and its application in prospectivity map... Wedemonstrate that a variety of trace elements, including most of the lanthanides, chalcophile, lithophile, and siderophile elements, can be pre...
Kalsilite-bearing igneous rocks are extremely rare, most known examples are volcanic. The few previously recorded kalsilite-bearing plutonic rocks are all Phanerozoic and mostly limited to the small ultrapotassic massifs of the Baikal–Stanovoi Rift in the Siberian Craton, the Greenland Batbjerg ...
The ever-growing roster of such examples indicates that they are the rule rather than the exception. Modern systematics of igneous rocks should have three, rather than two, main divisions: volcanic, plutonic, and volcano-plutonic. These three rock types reflect the overall progress of igneous ...
The latter rim is inter- preted as a metamorphic overgrowth on an igneous core. 5.2. Buck Ridge Volcanic Complex, BRVC (part of H6 or Noisy Complex) The unit is up to w2 km thick and consists of feldspar- and quartz-phyric igneous rocks that contain xenoliths of massive to pillowed ...
They have similar Sr–Nd isotopic ratios which lie in the range of I-type igneous rocks. Compared to the mafic samples from across the Turkish-Iranian Plateau, the mafic magmatic rocks (areas 6 and 7 in Fig. 9a) diverge from those fields defined by younger Eocene Mafic rocks from NW ...

Central Anatolia exhibits good examples of calc-alkaline and alkaline magmatism of similar age in a collision-related tectonic setting. Igneous enclaves are widespread in these calc-alkaline plutonic rocks of the CACC. Two types of igneous enclave have been recognized in the calc-alkaline Behrekdag...

The petrology of the last few decades considers two main divisions of magmatic associations: the volcanic and the plutonic ones. But new field data obviously show that modern systems of igneous rocks should have three, rather than two, main divisions: volcanic, plutonic and volcano-plutonic. ...
